The latter design employs a co-axial rotor combined with a pusher propeller
that has its origins in Sikorsky's X2 and S-97 Raider technology demonstrators.
The PT6A engine's flexible architecture and modular reverse-flow design simplify installation in both single- and twin-engine installations as well as tractor and pusher propeller
Because of the clearance required between the pusher propeller
and the ground, the pilot or passenger used to be seated quite low to the ground, which by default meant that the thrust line was much higher than is safe or practical.
The PT6A is not just one engine it's a family of engines using an innovative, modular and flexible reverse flow design which simplifies installation in both single engine and twin engine installations, as well as, in tractor and pusher propeller
The S-97's coaxial counter-rotating main rotors and a pusher propeller
are expected to provide cruise speeds up to 240 knots.
The coaxial counter-rotating main rotors and pusher propeller
provide cruise speeds up to 220 knots (253 mph).
2 kg (5 lb) with a 1-m wingspan, the "Wing" uses a battery-powered pusher propeller
to fly at up to 80 km/h (50 mph), with a 45-minute flight endurance.
Like the X2 demonstrator aircraft, the single engine S-97 RAIDER helicopter will feature coaxial counter-rotating main rotors and a pusher propeller
to provide cruise speeds up to 220 knots (253 mph) with dash speeds up to 240 knots (276 mph) or higher.
The German warplanes feature innovative technology, including electrically operated flaps and landing gear on the Focke-Wulf Fw 190 F; the first ejection seats, in the Heinkel He 219 A Uhu; and a rear pusher propeller
in addition to a conventional front propeller on the Dornier Do 335 A Pfeil.
Taylor and his team came up with a design that allowed a small, two-seat car to be converted into flight mode within five minutes by attaching a pusher propeller
It is powered by a UAV Engines Limited (UEL) AR731 rotary engine driving a pusher propeller
A pusher propeller
driven vehicle, launched from a hydro-pneumatic rail launcher, the Nishant carries electro-optic payloads of up to 45 kg and can fly just over four hours.
