    I’m terribly sorry that I pointed out conservation of momentum in a thread where you want to imagine helicopter rotors can just stop. I know that reality is inconvenient.

      You are failing to ask him a question: how does he know what he’s talking about?

      His phrase was “we teach” which implies he’s an instructor. You should ask him if he is.

      Being wrong is the issue.

      Rotors can add have seized, rotor failure is actually one of the more common modes of failure in a helicopter. Also notably I didn’t say it had to stop just that the rotor is no longer effective, like catastrophic blade loss.

        You said helicopters “just fall” when they lose power. That’s what spawned this tangent. You didn’t specify anything about the engine being seized, which is an additional issue.

        You are moving the goalpost, and asked someone to apologize to you for it. You’re a clown mate.

          Autorotation relies on one main thing, air being forced past a freewheeling rotor… Air that is being forced past because you’re falling.

          Notice the immediate loss of attitude? It’s because they’re falling, unlike planes which can generally glide after an engine failure.

          Specifically we’re speaking about helicopter ejection which in most cases means total loss of power or control or both. The only known helicopter eje tion seat(to me at least) to operate currently in modern combat is the ka 50/52.

          One like this one which happens to eject and notably falls like a stone.
