Matthew,
Without wanting to start a debate on this, I think rudestuff was actually refering to SWP due to Vortex Ring State.
Rudestuff, you are saying,
Imagine you drop vertically in autorotation, aiming to pull collective really aggressively to reduce your rate of descent to a survivable rate...
I guess it could be possible to do given the right equipment and pilot...
I don't think that VRS would develop fast enough in this short timespan to be of consequence
...the deceleration required to reduce the decent rate to a survivable one is quite a lot. This would sup a great deal of Nr, so could only realistly be done with a high-inertia rotor system or with absolutely split second timing and a sharp yank on the collective.
Well, in practice the timing would need to be so perfect that it's not a method to count on as a means of surviving an engine failure...As Nick posts below, an experienced pilot with 'split' second accuracy in timing and the right helicopter could pull this one off
So no, I'm not going to try that any time soon!
