Hawk Military Helicopter Military helicopter tail rotor solutions?
Is anyone working on solving loss of tail rotor function from RPG's as seen in the movie "Black Hawk Down"? I've wondered this for many years, whether or not it's possible to design a system whereby tail rotor loss of function could be minimized by some kind of emergency jet propulsion in the tail section to produce the necessary thrust for safe control of the helicopter or by directing engine exhaust in a sidewards manner much like an engine reverse thruster to minimize or eliminate torque thrust. I'm also wondering why the military does not employ the NOTAR system in combat zone helicopters to mitigate being brought down by RPG's. Any helicopter engineers or pilots wish to comment?
A helicopter will streamline straight if you have enough forward airspeed, in most cases 60-70 knots. The only good things about the NOTAR are that it's quiet and it minimizes tail rotor strikes. Other than that, it is too slow to respond. Once you put in pedal, it hesitates before it reacts.
