I'm going to go on a limb here, you'd need to put enough energy into the rotors of: helicopter weight * recovery time (so distance * descent rate) * gravity². that is a big number to get rotor mass * rpm to equal.
- TeMPOraL 7y agoAutorotation is already the standard emergency landing practice in case of loss of engine power mid-flight; I'm only guessing that landings could be performed in such a way as to maintain the capability for autorotation throughout the maneuver.
- Already__Taken 7y agoThat's what I was trying to explain, that energy to maintain rotor speed in an autorotation is stored in the height. To replace that is a damn big number you're putting somewhere else. Maybe landing rockets like the soyuz.
