Not to mention all the trash he was throwing into the other guys tail rotor. Quote Link to comment Share on other sites More sharing options...

Gomer Pylot Posted June 2, 2010 Report Share Posted June 2, 2010 You don't want to get too vertical in a tilt-rotor. VRS onset can be sudden, and in that configuration it's completely non-recoverable, one rotor stalls and the aircraft just turns over and crashes.

Vindicated0721 Posted June 3, 2010 Report Share Posted June 3, 2010 (edited) You don't want to get too vertical in a tilt-rotor. VRS onset can be sudden, and in that configuration it's completely non-recoverable, one rotor stalls and the aircraft just turns over and crashes. "V-22, once it has encountered Settling With Power (Army) or Power Settling (Navy), has a unique ability to get out of it. It does so without aggravation of the situation that normal helicopters do not have. The nacelles have a control switch which can be "Beeped" (Quick pressing of the switch to make small movements) up or down to change the angle of the nacelle. This can increase forward airspeed quickly without changing the pitch of the prop-rotors. Increasing airspeed and flying into clean air is the way to get out of the Vortex Ring State which is responsible for the "Settling" issues. The V-22 has the unique ability to increase airspeed without changing rotor pitch and can accomplish the airspeed increase much faster than any normal rotary wing aircraft." I agree getting too vertical with that kind of dual tilt rotor system wouldn't be the safest approach (especially with a cross wind), but that is technically true with all helicopters. But it is possible for the V-22 to recover from VRS. Of course not if you have over a 1000ft decent rate and you are only 150 ft off the ground like the ill fated V22 "test" flight.
