Simon Paul flies the Sopwith Pup from it's home base at Omaka in New Zealand. Take off - 0:56 Airstrip fly by - 2:47 Approach & landing - 5:58 I apologize for the Audio quality. Taken and Recorded by Gavin Conroy.
For a moment, I thought they were flying the old airplanes at Meadowlark Field again. That looks just like coastal Northern California in the summer. I had to look closely to see that it's not the Livermore Valley.
Reverend Henry Kane Oh! So..The trigger is placed there when the pilot shoots the MG?,Or he uses one hand to steer and one hand to fire at the same time to focusly lock on the target?
+Mudkow Must be a replica. According to Wikipedia there is only one original flying and that is at the Shuttlewoth Collection. en.wikipedia.org/wiki/Sopwith_Pup#Survivors
The only rotary engines that couldn't have throttles were the Gnome Monosoupappe series. This was because the exhaust valve was also the air intake, while the fuel and oil was sucked in through ports at the bottom of the cylinders. Pretty much every other rotary was of a conventional design where air/fuel/oil was injected through the back of the crankshaft by a carburetor, which the rotating action of the crank case would mix and sling the mixture through induction tubes to the tops of the cylinders and be sucked into the engine through poppet valves. Early rotaries didn't have throttles because the carburetors were primitive and didn't really allow it. Later carburetor designs had proper throttles and gave many rotaries proper throttle controls, although they maintained the blip switches.
GGigabiteM The Gnome Monosoupappe series had an inlet valve in the piston crown. The fuel/air mix was drawn into the crankcase and then, through the valve, into the cylinder. The exhaust valve was operated by an external push rod.
MarsFKA Sorry but that's incorrect. The monosoupape series only had the fuel and castor oil enter through the ports at the bottom of the cylinder. The air charge was inducted through the valve at the top of the cylinder. This is why no monosoupape engine had a throttle, because it was impossible. Varying the fuel/oil mixture without varying the air charge can lead to severe engine damage. If the engine was run too lean, the cylinders could be blown off or the engine would severely overheat. Too rich and the engine would hydrolock or foul out. Variable valve timing was also tried, but the valves would burn frequently due to improper settings. The valve was a dual purpose air intake and exhaust valve using a push-pull rod operated by a complex series of guides inside the engine. This is why the valve doesn't have a return spring, because the rod both pushes the valve in and pulls it out of the cylinder.
Just a small thing, "Monosoupape" means one valve, Obviously mono means one and valve in French is soupape, amazing engineering,...love to hear the respectful and knowledgeable banter, very good, thanks
