      Heck if accelerating to Mach 19 in about 2 meters is acceptable you could just disable the rotors and only experience an acceleration of less than Mach 1 in just a few meters.

        What about that fancy thing that stops table saws when you touch them? Just get one of those and stop the rotors. I’m certain there’s no physical reason this wouldn’t work.

          The energy will have to go somewhere, so the passengers can stand up with their arms stretched, and when the rotating energy reaches them they can jump out and they will start spinning and their arms will act as rotors keeping them in the air long enough to reach land safely. You just need to make sure there aren’t a lot of people on board because the energy will have to be divided on all of the passengers, if there isn’t enough for everyone, they will fall to their death.

            The energy can go in to ejecting the seat!

            If it requires the energy of the rotors being stopped suddenly to eject, there’s no chance of getting filleted

      When helicopters lose power they just fall. If the rotor head isn’t decapitated then when you get ejected sideways there’s s no zero chance you’ll be julienned on the way down.

      It’s why the most (only version currently in operation) common method of helicopter ejection severs the head or blades while it’s still rotating so it/they spin off and hopefully away and then the seat rockets away.

          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.

              Tell me you didn’t read the root comment without saying you didn’t read the root comment.

              Losing altitude can be described as falling because the fucking thing is unpowered.

              Agreed, though irrelevant.
