A Marriage 41 Years in the Making

Susan and Dave
Dave O’Malley, the genius behind all of the marketing and branding at Vintage Wings, the man who has donated over 6,000 hours of volunteer time to Vintage Wings, the pen that writes most of the weekly articles you receive in your inbox, recently took the plunge and got married.
After a 41 year courtship (and a couple of marriages) Dave and Susan tied the knot on Saint Patrick’s Day - the day they met in 1971 (in a conga line!). Dave was 20 in 3rd year Architecture and Susan was 18 in Nursing school. They drifted apart then back together again.
Cool eh?
Many heartfelt congratulations to you both from your family at Vintage Wings.

Swordfish Gets a Torpedo

IMG290

Vintage Wings master painter Korrey Foisy is currently working on creating a mock torpedo for the belly of the Swordfish.

The torpedo will look like metal, but is actually fabricated from Divini Mat, a high-density foam with fibreglass scrim on the back. The foam is coated with 8.9oz 7781 8-harness fibreglass (a common type in aviation). This will make the torpedo extremely light and very strong.

The mould for the torpedo is an 89-inch circumference plastic tube. The Divini Mat was laid around the tube and coated with fibreglass and resin. It was then vacuum bagged overnight to remove any air and fully impregnate the fibreglass with the epoxy resin. A cotton breather was laid on top to absorb any excess resin.

After the epoxy had hardened and been vacuum bagged overnight, the torpedo was gently and oh so carefully removed from the plastic mould.

Hollywood Stars and Hangar Dump

 

This morning Chad Legault from Gloucester High School came with his wife Michelle to do some filming at the Vintage Wings hangar. Chad is studying to be a Tech teacher at Queens University, and is currently doing a co-op placement at Gloucester High School. He came to interview AMEs Angela Gagnon and Vanessa Lefaivre in hopes of motivating some of his female students, and students in general, to consider a career in aviation technology.

Angie and Vanessa will be signing autographs tomorrow at 10am.

This afternoon the whole hangar was dumped – the aircraft you want is always at the back, isn’t it?

The Swordfish and P40 got a thorough run up on this slate grey afternoon.

Monday Hangar Update

Mon, Mar 12, 2012

You know spring is in the air when the hangar doors do not remain tightly sealed against the bitter winds, but sit cracked open a few feet, allowing soft, warm breezes to percolate into Vintage Wings headquarters, flowing in and around the aircraft in various states of disrobement.

In a nutshell, here is the status of our aircraft:

F-86 – Waiting for ejection seat parts to arrive from Cold Lake, but other than that annual is almost done. Noise making (run-up) scheduled for tomorrow.

Spitfire Mk XVI – Currently sitting on jacks, without an engine. Spitfire is undergoing an engine swap (more on this in a later blog) – freshly-overhauled engine should arrive by end of month from P51 Factory down in California. Corrosion was found around rivets on the header (coolant) tank, along with signs of previous coolant leaks and wear. The header tank could not be repaired in house, so has been shipped to England for repair. During the annual inspection, some play was found in the gear, and we are currently waiting on non-destructive testing (NDT) results for the part that may need to be replaced. The seat has also been removed, and is currently being used to form a mold. This mold will be used to make a seat for the Mk IX Spitfire out in Comox. Other components being worked on include the gear legs, battery and pneumatic system.

P51 – Missing one bank of cylinders (B Bank), away being repaired. Like the Spitfire, a leak was discovered in the header tank (using tips from P51 Factory brought back from the Warbirds Operators Conference). Our in-house welding expert is currently working on the repair.

Mustang Header Tank

P40 – The radiator just came in and will be installed shortly. After topping up the coolant, the aircraft will be ready for a run-up, followed shortly (hopefully) by maintenance sign-off.

Hurricane – The annual inspection and run-up are complete. One outstanding issue is the intake box – it was cracked. It has now been repaired and is in the paint shop, awaiting sky blue paint.

Corsair – Annual still to be completed. A flat tire was changed, and the aircraft consequently requires a gear swing to ensure proper clearance – the new tube has a hard valve stem versus a rubber one.

Lysander – Changing over from pneumatic to hydraulic disc brakes. Currently sourcing calipers and discs. Annual to be completed.

Swordfish – Working on making a torpedo for the Stringbag. Getting details and info from our friends at the Canada Aviation and Space Museum.

Harvard – Annual complete. Flight to be done later this week to break in new cylinder.

Stearman – Paperwork is all that is left before she’s airworthy again.

Cornell – Waiting for oil cooler, gaskets and vacuum pump. Once those are installed, the annual will be complete. A new prop was put on.

Cornell items remaining

Finch – Kinner engine currently being overhauled. Due back at the end of the month.

Tiger Moth – Annual is done. ELT has been sent out for recertification.

The Story Below High Flight

Adapted from “High Flight: The story of John Gillespie Magee” by Richard P. Bentham, from the Summer 1996 edition of the Journal of the Canadian Aviation Historical Society, Vol. 34 No. 2.

All photos from the public domain.

“Nothing that John Magee was involved in was ordinary,” wrote R.P. Bentham.

 

John Gillespie Magee

“John Magee had ties with the United States, England, and Canada. He was an American citizen by birth, but was British to all appearances and in his heart. He was not claimed as one of their own by the British because he was an American citizen, and he was not embraced by the Americans because his ties to that country were tenuous to say the least. How appropriate then that with one uneasy foot in the USA and the other in England it would be the last 15 months of his life as a pilot in the RCAF where he would find a sense of belonging, fulfilment, and purpose – and the inspiration to write High Flight.”

John Gillespie Magee was born in China to American missionary parents. He was a mischievous, high spirited child. He attended public (private) school in England, where his housemaster described him as, “intelligent, volatile, emotional, untidy, thoughtless and keen.” He was usually at the head of his class, and at age 16 won a poetry contest while attending the famous Rugby School.

In 1939, Magee was sent to school in the United States. Having attended a British school and having great knowledge of Plato, Aristotle, English literature and the ability to read Greek did nothing to help him fit in with his new American peers. But there was little love lost between them, as Magee described his fellow students as “excessively characterless and unintelligent.”

While he may not have fit in well with the American boys, the attractive young man fared much better with the girls and was a regular at parties, dances and social events.

In the summer of 1940, Magee won the top scholarship to Yale University – but his passion lay elsewhere and he soon joined the RCAF. He was selected for pilot training in Jan 1941 and was overjoyed. He had never wanted anything so much in his life.

Magee’s Report on Pupil Pilot read: “Very good pilot prospect. Commission material. Keen, alert and conscientious. Deportment is excellent. Possessed initiative and ability.”

Being in the RCAF gave him a goal and purpose in life - he matured from a lost adolescent, disillusioned with “modern” society, to a happy, mature, focused young man. While his parents were initially less than thrilled at his abandoning university, they embraced his decision when they saw the positive changes the RCAF brought about in him.

Magee began his flying career in St. Catharines, Ontario, at No. 9 EFTS, on the finicky (though the British may call it forgiving) Fleet Finch; he soloed after six hours (the average was nine). He may have been an above-average pilot, but his flying training also noted that he was “somewhat overconfident.”

From St. Catharines, Magee continued his training at No.2 SFTS Uplands, Ontario, on Harvards and Yales, which he loved. He got a dose of humble pie when he ground looped a Harvard on May 13.

June 16, 1941, was a proud day for Magee - that is the day he received his wings. Again, his flying report was excellent (“Almost exception in aerobatics.”). Magee was also a hit with the ladies in Ottawa; he “apparently managed to meet most of the girls in Ottawa while still doing well enough on the SFTS course.”

Just 11 days after his 19th birthday, Magee was commissioned as Pilot Officer John G. Magee, making him one of the youngest officers in the RCAF. Shortly thereafter, he travelled to the United Kingdom, spending a week hiking in Iceland along the way. During the last part of the trip to the Pilot Reception Centre at Bournemouth, the trains were so overcrowded that Magee and his friends slept in the overhead luggage racks.

Every pilot wants to fly Spitfires, and Magee was no exception. Imagine his thrill when he was selected for Spitfires, an aircraft at the absolute leading edge of technology in 1941.

His assessment at the OTU was as follows: “Very keen. Might make a very capable leader. Very calm in the air. Has shown patches of brilliance in his flying in contrast to moments of carelessness. An inclination to overconfidence which squadron experience should help eradicate. Will develop into a very capable pilot. Good average.”

From the OTU, Magee was posted to 412 Squadron on September 16, 1941. It was shortly after his first Spitfire flight that he penned High Flight. In a letter home he wrote, “I am enclosing a verse I wrote the other day. It started at 30,000 feet and was finished soon after I landed. I thought it might interest you.” On the bottom corner of the page is noted, “PTO for ditty.”

High Flight Original

Copy of the original High Flight

This poem went on to become one of the most loved and well-known poems in aviation history. It has been recited at thousands of aviation events, been set to music, has shown up in Hollywood movies, and been quoted by Presidents and astronauts alike. It has captured the imagery and magic of flight felt by all aviators.

Magee’s letters home at the time also indicate that he was having the time of his life: “My squadron contains surely the grandest bunch of people that ever lived. I am sure I am going to be very happy here. It’s an all-Canadian squadron. The squadron leader is a peach, quiet but efficient and thoughtful.”

Magee’s first introduction to combat was a sobering one: six Spitfires took off and only three returned. Magee was the sole survivor of his section of four. He flew the mission in Spitfire AD291 – the same aircraft in which he would end his life on December 11.

He wrote to his parents: “I have at last been in action. I was flying in the leading section of 4 as the new CO’s wing man. I was the last man to see him alive, as just before we took off, he was giving me a little fatherly advice as it was my first action and I was a little uneasy!! We were jumped by 10’s coming in swarms out of the sun. We turned into them immediately but I turned so violently that I spun down a good many thousand feet and got away. I was the only one to avoid getting hit. The CO and two others (in my section) were all shot down. The CO Kitt Bushell was one of the grandest men I have ever known. The mess has an air of forced cheerfulness just now. Our losses (the first we have sustained) were pretty hard to take but we needed some waking up. Everyone is determined to get something next time.”

Towards the end of November 1941, Magee was flying twice a day, practicing gunnery, formation and night flying. In a letter to a friend he wrote, “Really you have no idea how terrifying – and yet how marvellous – it all is….I have never had such fun in my life.”

While Magee may have been having fun, he was not immune to the sobering reality of life as an operational fighter pilot. He wrote to a friend, “Frankly, however, I do not expect to last. It’s not a very sensible thing to talk about on the whole, but to be good you’ve got to take your chances and you can’t win all the time. I expect to end my days here in England…”

On December 11, 1941 at 10:40am, 19-year-old P/O Magee took off in a Spitfire Mark VB in a section of four to practice cloud flying, formation and combat.

An hour later the section was returning to base, diving down through a hole in the clouds in a loose line-astern formation. Magee was third in the line and collided with an Airspeed Oxford trainer flying just under the cloud deck. He was seen struggling to get clear of his aircraft but both aircraft hit the ground near the village of Scopwick in Lincolnshire. Both pilots were killed.

R.P. Bentham wrote that, “A mid-air collision is one of the cruellest tricks that fate can play on a pilot.”

Magee’s grave marker in Scopwick village cemetery reads:

“Oh! I have slipped the surly bonds of earth

Put out my hand and touched the face of God.”

Pressure Systems: From High to Low

clip_image002

Note: all pictures from the public domain

The atmosphere has weight. Put another way, the air exerts a pressure on the surface of the earth. How much? Per square inch, the air weighs 14.7lbs at sea level. Or, the weight of the air causes a column of mercury (mercury barometer) to rise 29.92” at sea level. Or, for you metric folks, the air exerts a force of 1013.2 kilopascals or mb.

Imagine a column of air. The higher you rise in that column, the less air there is above you pushing down on you, or the less pressure exerted. The average decrease in pressure is 1”Hg per thousand foot ascension.

Now this of course is in an ideal world. In reality, the air pressure is continuously changing at various rates at various locations – and this information can tell us a lot about current and future weather conditions.

For this reason, pressure readings are taken at weather reporting stations, and transmitted to forecasting stations where they are plotted on maps. Areas of like pressure are joined by lines called isobars. When these isobars are drawn, they form patterns on the map. They never cross, but form concentric circles depicting areas of high and low pressure. Like lines on a contour map, high pressure areas correspond to hills and low pressure areas to valleys. It is important to note that high and low pressure systems are only high or low relative to the air surrounding them – thus a low could be 1012mb or 992mb, depending on the air surrounding it.

clip_image004clip_image005

But what exactly is a low pressure area? A low pressure area is defined as a cyclone, depression or simply as a low. It is a region of relatively low pressure, with the lowest pressure at the centre. Lows are areas of ascending air, with the air churning inwards towards the centre of the low in a counter-clockwise fashion. As we learned from Weather 101, rising air expands, cooling as it does so, and often condensing. As a result, lows are often associated with low cloud, poor visibility and precipitation. Just remember this: lows = bad weather.

clip_image006

A high pressure area conversely is defined as an anti-cyclone or a high. It is a region of relatively high pressure, with the highest pressure at the centre, decreasing towards the outside. The winds around a high travel clockwise, spinning into the centre. The air in a high is descending, increasing in pressure and consequently warming. This means that the saturation point increases (the air can hold more moisture) and there is very little, if any, precipitation. High pressures are associated with weather that is fair and clear, with light to moderate breezes. Highs tend to move slower and remain more stationary than lows. Just remember this: highs = good weather.

So the next time you’re flipping channels, stop for a just a moment longer at The Weather Network. See if you can make a bit more sense of the weather man’s forecast. And then wait and see if he’s right!

The Adjutant’s Boots

A follow-up to a recent post about veteran Bob Buckles, from our dear friend Bill McRae. Reprinted from the May 2003 issue of the Observair. Thank you to Timothy Dube of CAHS.

“When I was posted out of No. 132 RAF Squadron in the spring of 1942, the Adjutant – whose name I regretfully cannot recall – presented me with a new pair of pre-war RAF all-leather flying boots.  At the time we were flying in an economy, canvas-topped, version of the all-leather boot.  The Adjutant’s boots travelled with me to West Africa, where I hung them up to keep the scorpions from using them as a home and protected them as well as I could from the ravishes of the humid climate.  It was never my intention to fly with them, but rather to bring them home eventually to exhibit in my den as a memento of the war years and No. 132 Squadron in particular.  In Africa, I flew with either ankle-length desert boots or my calf-length mosquito boots.

Returning to the UK and joining No. 401 Squadron in the spring of 1943, I was issued with the new flying boots, with insulated suede tops which could be torn off to leave a sturdy, Oxford-type, walking shoe.  This was much more practical should an airman find himself walking around in enemy territory.  In the meantime, my all-leather boots went back into temporary storage.

On 20 December 1943, on leaving the briefing tent following briefing for a wing sweep, I was approached by Bob Buckles, another 401 pilot, who asked if he could borrow my ‘spare’ pair of boots, since his were in the shoemakers.  Without thinking (I should have given him the issue boots and worn my good ones), I answered “Sure,” adding in jest  “but don’t get shot down.”  It was a high level sweep to Eindhoven, twenty miles from the German border, then around Brussels and back out.  Just north of Brussels, 411 Squadron saw a Do.17, which they destroyed.  Then we spotted a Ju.88; the recently-appointed 401 Squadron ‘A’ Flight Commander, Lorne Cameron, and his number two for the day, Buckles, went down to attack.  Cameron gave Buckles a crack at the target, but I guess he did not go about it the right way, because the next thing I saw was the telltale stream of glycol, which indicated Buckles would not be coming home that night.  I must confess that I only vaguely saw Cameron finishing off the Ju.88; I was focussed on the parachute, on the end of which was Buckles, and on the end of Buckles – my boots!

With the Wing reassembled for the return trip, we were almost at the coast when the wing leader – for reasons I have never been able to determine – called for a 360 degree turn.  Turning thirty-six Spitfires – flying in loose formation at staggered heights and with some close to cloud – could be a bit dicey.  When we straightened out again two of our pilots – Maybee and Morrisey – had collided and were now on their way down in their ’chutes.  It was not until thirty years later, when I met Maybee at a reunion, that I learned why the collision had occurred.  He told me that in the turn he had unexpectedly found himself in cloud; there was a loud bang as he collided with Morrisey who was in the same cloud, and they were both fortunate in being able to get out.  The CO was furious when we landed after 2 hours 15 minutes.  It was not good on our record to have lost three pilots and three recently-received Spitfire Mk. IXs, with only one Ju.88 to show for it.

At the same reunion thirty years later, I met Buckles.  Of course, the first thing I said was “Where are my boots?”  Each time we ran into each other again I would kid him about my boots, until his wife, tiring of this little game, presented me with a tiny pair of souvenir mukluks, saying: “Here are your boots, now don’t bug Bob again.

So, with no all-leather RAF flying boots to display in my den, there sits in a prominent spot in front of my aviation books, the little mukluks; reminding me of those far away days – and the Adjutant’s boots.

It's the Harvard's turn

By B.Reid

As the winter progresses, the annual inspections at Vintage Wings of Canada progress. One by one, the aircraft are taken apart to a certain extent and looked over in accordance with manufacturers recommendations and government directives for any evidence of deterioration.

Overall, the aircraft, which flew extensively, last year across Canada on the Yellow Wings program, was in very good shape with one exception. One of the cylinders in the Pratt & Whitney R-1340 engine is in need of replacement.

Of the five Yellow training aircraft in the Vintage Wings collection, the Harvard is easily the most powerful. It was the aircraft that students went to for advanced training and on which they earned their coveted pilot’s wings. And advanced it is. With retractable gear, a constant speed prop and many other much more complicated systems, there is plenty to keep a pilot busy both on the ground and in flight.

The Harvard is not known for its docile handling characteristics. Stalls are abrupt, ground loops are not uncommon for the unwary and even taxiing can present challenges for the neophyte. All this and more created excellent training for students progressing to the even greater challenges of a high speed fighter aircraft. Harvard was definitely an appropriate name for this school of higher learning.

Actually, it all started back in the early 1930
s with North American Aviation. Originally a holding company for several well known airlines and aircraft manufacturers, the Airmail Act of 1934 broke up these holding companies. North American decided to become an aircraft manufacturer itself through its General Aviation manufacturing division in Maryland in the former Curtiss-Caproni facilities.

One of its biggest successes would be the trainer that eventually became the Harvard aircraft that we in many Commonwealth countries know. The original aircraft, known as the NA-16, was rolled out with an open cockpit and fixed gear. Various different models (with a canopy) were delivered to the Army Air Corps and the Navy. One might notice that the bolted-on wings to the centre section resemble the DC-3. This was no coincidence as Los Angeles based North American had recruited engineers from Douglas in nearby Long Beach.

As time progressed, so did the aircraft with retractable gear and more powerful engines. Difficult handling characteristics were tamed somewhat with redesigned wings and tail surfaces. In fact, some very early models even had slats on the wings.

Designations for the aircraft became quite complicated with various charge numbers from the manufacturer(such as NA-16 for the prototype) various air forces and navies around the world applied their own designations. To the United States Army Air Corps (USAAC) she was originally known as the ‘BC-1’ (Basic Combat - 1) and later as the ‘AT-6’ (Advance Trainer - 6). After the USAF became a separate service – this remarkable trainer was re-designated as the ‘T-6’. For the United States Navy (USN) – they were known as the ‘SNJ.’ In Canada and Commonwealth service, it was called the ‘Harvard.’ In Australia, a licence-built derivative was called the ‘Wirraway.’ The earlier fixed gear versions called the ‘Yale’ by Commonwealth air forces, were known as the ‘BT-9’ and ‘BT-14’ (Basic Trainer - 9/14) by the USAAC and called the ‘NJ’ by the USN. In all, over 18000 of these  aircraft were built.

Canadas experience with Harvards started out in July 1939 with the Mk. I delivered from the expanded production facilities in Los Angeles. In fact, the RCAF had an office at the plant(North American later opened a second plant in Dallas). After Canada’s war declaration, many deliveries were flown to the border and towed across in order to comply with Americas Neutrality Act. The Mk. I was easily identified by its rounded rudder and its fabric fuselage. RAF ordered versions were NA-49's while RCAF ordered versions were NA-61's but they were virtually the same. The Mk I Harvards would last in flying service only until 1943. None exist today.

Mk. II versions for the RCAF were produced by North American as well as by Noorduyn with final assembly at the Cartierville facility in Montreal. These had metal skin, a stretched fuselage and the familiar triangular fin. Handling characteristics were improved with a redesigned wing and tail which included less sweepback and more of a tapered shape.

In 1940, the RCAF also received fixed gear models diverted from delivery to France after its downfall. They were designated as the Yale. Upgrades to Canadian standard included adapting metric instruments to imperial measurement and redesigning the reverse operation throttle installation.

The Harvard was such a success as a trainer during WWII that in 1952, Canadian Car & Foundry which had taken over the Noorduyn company was awarded a contract for 270 upgraded Mark 4 Harvards which were built in what is now Thunder Bay. Many of them were assembled from spare Mk. II components, however, in its final form the Mark 4 had a 24 volt electrical system and greater fuel capacity among other improvements. Its most visible difference is the redesigned canopy.

The Vintage Wings of Canada Harvard is a Mark 4 version painted in Mk. II colours in honour of John Gillespie Magee, and is known as the High Flight Harvard in honour of the man and his poem.





North American’s decision to no longer produce fabric covered Harvard's was of great convenience for maintenance personnel as the side panels can be quickly removed for interior inspection. They have been removed from both sides in this picture. This allows a great view of the inside. The circular pieces are the trim wheels for the rudder and elevator. The red topped handles in between the wheels are the wobble pump handles. Normally only used for start, they will be used continuously for the rest of the flight if you lose your engine driven fuel pump. The long red handles are the fuel selectors. If you look closely, you can see the rods from them angling down and meeting at the selector valve.




A closer view of the trim wheels with their yellow painted notches to be used as a reference for the takeoff setting. The trim wheels, wobble pump handles, fuel selectors throttle quadrant levers and gear handles are all interconnected between the two cockpits.




With panels removed, you can see the tailwheel declutching mechanism. For taxiing the pilot can steer the tailwheel (15° left and right) through the rudder pedals. However, for very sharp turns the pilot disengages the tailwheel steering and the tailwheel castors freely. This is done by pushing the control column fully forward (to disengage the tailwheel clutch) – and then using power and differential brake to turn sharply. Whenever towing the Harvard(or the P-51), make sure the controls are locked. That way, the control column is fully forward and you won’t damage the tail wheel unit if it tries to swivel.

Looking at the back side of the engine mount you can see that the oil tank on the upper left is well separated from and aft of the Pratt & Whitney R-1340 Wasp engine. Three exhaust pipes can be seen entering a round circular unit which is a heater muff. Air in this muff is heated by the exhaust tube and is available as carb heat.


The non-geared version of the Pratt & Whitney R-1340 Wasp supercharged engine was used on the Harvard. The Yale uses a Wright Whirlwind engine. There are several intake pipes for ducting air around the engine. The two most noticeable ones at the 9 and 2 o’clock positions are to direct cooling air to the magnetos. At the top of each cylinder is a smaller hole directing air through a tube to its rear spark plug.




Forr those into finer details, here is a difference between the Harvard Mk.I/Yale wings(top picture) compared to Harvard Mk. II /4 wings(bottom picture). On the later aircraft, the sweepback was reduced on the wings and horizontal tail by about 2.5° for better stall characteristics. In order to maintain a similar wing area, the trailing edge was swept forward. The rod you see in each picture is for the aileron tab. It has to be attached to a non-moving portion of the wing in order for the tab to deflect with aileron movement. This silver piece in the top picture is actually fixed to the main portion of the wing, one of three aileron attachments The ailerons on the newer wings had a different style of wing attachment. In the lower picture, you can see that an arm was attached to the bottom of the wing to reach back and function as the fixed airframe part attached to the trim tab rod.



Out with the old cylinder, one of nine on the Harvard engine. The R-1340 Wasp was the first engine developed by Pratt & Whitney. It was classified as a top-secret design when it was developed in the 1920’s. It was the first American radial engine to use a forged crankcase resulting in a much stronger engine. Other P&W engines named after stinging insects were the Hornet and the Yellow Jacket. On this cylinder, the exhaust port on the far side of the cylinder is the one surrounded by more cooling fins.


This picture really shows the exhaust routing clearly. From each cylinder into an exhaust ring and the into an extended tube. The extended tube is specifically for the heating pipe that you can see at the front of the exhaust pipe where fresh air enters and at the rear of the exhaust pipe where the now heated fresh air is directed into the cabin. This extended pipe was only installed on Mk. II and later Harvards. Early Harvards and all the other named types of this aircraft from North American and licenced producers had a short pipe with no heater.



The heater system for the Harvard taken apart. Hot exhaust air flows through the large pipe. Fresh cold air flows through the dimpled small pipe which runs though the large pipe allowing the cold air to be heated prior to being routed into the cabin. Early Harvards did not have this heating system and instead had a short exhaust pipe which on occasion due to overpriming created a localized fire on fabric  covered aircraft.


 View of the back side of the piston which has 5 rings, consisting of two oil rings and 3 compression rings. The machined holes on the interior of the piston line up with the oil rings allowing oil to return from the cylinder back into the engine. The fins are for cooling and to provide lightweight strength.
