Certain propeller driven aeroplanes are equipped with piston engines whose fundamental "firing"-frequency coincides with the rotational frequency of the propeller. Taking the two sources as a system ...
Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these characterful machines; the final fighters were over six times faster and ...
The A-1, a piston-engine propeller plane, held its own even as the US embraced jet-powered aircraft. When the A-1 left US service in the 1970s, about 30 variants had been used for different missions.
Speed, efficiency, and altitude are the name of the game when it comes to aircraft; all of which benefit from smaller engines. "There's no replacement for displacement" applies less to piston-engine ...
