The Defiant has more of a traditional helicopter look but with counter-rotating coaxial main rotor blades and a "pusher propeller
" at the rear to increase airspeed and maneuverability.
0 VTOL concept has two electrically driven rotors to ensure safe vertical take-off with horizontal thrust being provided by an electric powered, rear mounted pusher propeller
, the company writes in its press release.
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.
A larger pusher propeller
in the plane's tail serves at its primary propulsion unit.
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
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).
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
