A daft question about helicopters
I watched a documentary of some sort a couple of days ago about autogyros, with Ken Wallis, and I got to wondering if something like that could be used with regular turbine helicopters?
I mean in the unfortunate event of losing the tail rotor, if you could decouple the turbine engine and rev it right up to use the thrust from it to either prolong the glide or perhaps even have some level flight, to give you options as to where to land. The rotor would stay spun-up just like a regular autogyro, etc.
But I suspect there wouldn't be anywhere near enough thrust to get any useful forwards speed ... ?
