Very close.......What's the principle
The Gyroscopic Principal, which allows it stable flight as it glides to the ground. The machine is the Gyrocopter.
Near enough.
I was after auto rotation.
I am a old gyrocopter pilot from way back.
Auto rotation of a spinning air foil only occurs with certain designs of air foil and only at a air flow angle of incidence of less than 2 degrees.
The idea of rotary wing flight came from a sycomore seed and without auto rotation helicopter flight would be deadly if the engine fails.
A helicopter with enough height can glide to a safe landing without the engine.
Provided it still has a Tail Rotor.
Its still your go R I need to sleep.
Don't need a tail rotor for autorotation as there is no drive and therefore no torque reaction though the air frame.
Gyrocopters have no tail rotor, only a rudder to steer and in a vertical decent don't even really need that just the same as the sycamore seed.
I realise I forfeited my go before, but I'm going to jump in anyway. [bigwhistle]

Have a crack at this one ladies and gents.
[edit] and why is it so 'different' to what has been 'normal' in this application ?
semisealed compressor?
Of a type, but semi-hermetics have been around since Moses, this is different, very 'Jetsons'.Quote:
