F4U-4 Corsair Picture from RC Model |
The Vought F4U Corsair is an American fighter aircraft that saw service primarily in World War II and the Korean War. Designed and initially manufactured by Chance Vought, the Corsair was soon in great demand; additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A.The Corsair was designed and principally operated as a carrier-based aircraft, and entered service in large numbers with the U.S. Navy and Marines in World War II. It quickly became one of the most capable carrier-based fighter-bombers of the war. Some Japanese pilots regarded it as the most formidable American fighter, and U.S. naval aviators' claims suggested an 11:1 kill ratio. Early problems with carrier landings and logistics led to it being eclipsed as the dominant carrier-based fighter by the Grumman F6F Hellcat, powered by the same Double Wasp engine first flown on the Corsair's initial prototype in 1940. The Corsair's early deployment was to land-based squadrons of the U.S. Marine Corps and U.S. Navy.The Corsair served almost exclusively as a fighter-bomber throughout the Korean War and during the French colonial wars in Indochina and Algeria. In addition to its use by the U.S. and British, the Corsair was also used by the Royal New Zealand Air Force, French Naval Aviation, and other air forces until the 1960s.From the prototype delivery to the U.S. Navy in 1940, to final delivery in 1953 to the French, 12,571 F4U Corsairs were manufactured in 16 separate models. Its 1942–1953 production run was the longest of any U.S. piston-engined fighter.

| 1923 Dunelt 499cc Two Stroke Motorcycle |

| Dunelt two-stroke cylinder with stepped piston – Montagu Cars and Motor Cycles |
The patented Dunelt 499cc engine had a cylinder barrel with different upper and lower bore diameters, in which slid a ‘stepped’ piston with two matching diameters.
The pistons were double diameter and also bi-metallic, with an iron/steel section cast in for the ring grooves – not cheap to make.
Where a standard-bore engine had 499cc-limited mixture induction and transfer ability, the Dunelt engine could suck into its crankcase and transfer into the cylinder about 770cc of charge petrol-air mixture.
A deflector piston ensured that most of that mixture remained in the combustion chamber.
This basic form of supercharging had the desired effect and, in conjunction with a heavy flywheel, earned the Dunelt a reputation for being a torquey, ‘slogging’ engine that lent itself to sidecar applications, including commercial service and delivery tasks.
Also, a Dunelt motorcycle was the first to cross the desert from Cairo to Siwa Oasis and back in 1924.

The oasis is in a deep depression that reaches 62 ft below sea level. . . . The depression is fertile due to both natural flowing artesian wells and irrigation. . . . The oasis supports the cultivation of thousands of date palms and olives. - Wikipedia

| 1965 DMW Typhoon 500 |
Spurred on by Metal Profile's enthusiastic boss, Harold Knock, DMW created its 500 racer by the simple expedient of joining two Hornet engines together, an arrangement that afforded the prospect of 60-70bhp at a time when a good Manx Norton managed around 52 horsepower. A pair of Alpha crankcase assemblies was used, sandwiching a special straight-cut primary transmission. The latter consisted of a jackshaft in an oil bath, from which drive was taken to a secondary transmission and thence to the Albion five-speed gearbox via a Royal Enfield Interceptor clutch. Ignition contact breakers were mounted at one end of the jackshaft but were later moved to the crankshaft end.
This bike had problems: vibration and weak brakes. People fiddled with it, but it never became the world beater they were hoping for,

| 1946 White WA22 Semi-Tractor |
1946 White WA22
Engine: 386 Cubic Inch White 6-Cylinder Gasoline
Transmission: 4-Speed, 3-Speed Auxiliary
Top Speed: 55 MPHThis 1946 White WA22 was originally used as a moving truck. It rolled off the assembly line in Cleveland, Ohio in April of 1946. Its original owner lived in Beaver Dam, Ohio. This truck was licensed and used by Mayflower Transit until 1979; it had only one primary driver for 33 years. It has been in the Iowa 80 collection for a number of years, but was newly restored in 2012. The truck can get up to 55 mph, which was more than sufficient given that the speed limit where it mainly operated didn't exceed 45 mph. This White has one of the first integrated sleepers seen in production, and it is only 18 inches wide. Still, that's wider than the truck's narrow cab. To add the sleeper, they had to angle the doors out. If you stand in front of the truck and look at the side you can see that when the windows were open, bugs would come through; if someone was in the sleeper, they'd get hit in the face by bugs as the driver traveled on down the road. The windshield wipers are air-operated; air from the brake system is used to power them. That is how it was done until the ‘90s. The truck does have a heater which is a bit unique for the time. This truck also has one of the last wood-structured cabs that White ever made; in 1947, all cabs produced were steel. Truck driving was - and still is - a hard job. However, running a truck like this made it harder. It has a crossover gas tank which holds about 100 gallons of highly flammable gas and sits right behind the cab. Diesel fuel can catch fire, but not nearly as easily as gas. Drivers that got into a wreck would burn up instantly.

| 3 cylinder compound locomotive steam engine This is only image I could find of a three cylinder engine. Sad, very sad. |
The three cylinders are high on my list of unique designs that never took off over here in the US.
3-cylinder locos had a speacial exaust chuff as well, from the four chuffs per driver revolution on normal engines, 3 cylinders had six chuffs, making for some very interesting “stack talk”
While here in the US they never really took off, they became fairly common across Europe. Among some notable European 3 cylinders is the A4, thats right, the “Mallard” was 3 cylindered, along with her sisters who still operate today!
[3 tiny pictures that purport to show the center cylinder of 3 cylinder locomotive. They made no sense to me. Perhaps they would if you were familiar with these locomotives.]
The center cylinder yielded more power in a smaller locomotive, the #12 (pictures above) is an 0-8-0, but still produced more than 60,000 lbs tractive effort! Thats more than some 4-8-2’s and 4-6-4’s of the time period!
Unfortuantely, the 3rd cylinder was difficult to service, and the costs related to maintenance outweight those saved by fuel economy. These engines became known as “Roundhouse Queens” as they sometimes spent longer under repair than in operation.
This is probably more than you wanted to know,
