The thing I love about Gyro's; because the rotor is just a free-wheeling rotating wing during normal flight, if the engine fails during flight, the craft still continues to fly, with the rotating wing still providing lift, and the pilot gently manoeuvres it to the ground under full control.
Providing that air is passing over and under the rotor blades, it will continue to rotate freely, providing lift!
The engine is only used
to pre-rotate the rotor on the ground via a flexible drive; once the rotor is up to speed it is disconnected from the engine (gearbox), and then the engine merely provides forward thrust!
There is no direct connection between the engine and the rotor, as there is in a Helicopter!
...fascinating little machines!
Well worth trying out in the Flight Sim!
...go on...your will love it!...trust me...
