Most of us fly aircraft powered by
piston engines, a basic technology dating back to the late 19th century.
The new engine would weigh a fraction of
piston engines in the 100 horsepower class and have 10 times the life span, according to the Air Force.
A free
piston engine is a heat engine with pistons that move back and forth to extract work from a fluid, or to act as a pump.
Propeller drive units with four-stroke
piston engines are mainly used for the propulsion of UAVs weighting more than 50 kg.
Typical was the O-1E, powered by the 435-horsepower Curtiss V-1150-5
