Web14 mrt. 2014 · $\begingroup$ In some helicopters with high inertia rotor systems (basically heavy and store a lot of energy simply through rotation), auto rotations can be non-events. The B47 could be landed, picked up, turned through 180 degrees and put down again all without the engine. The other great thing about engine failures in many helicopters is … WebWhen a helicopter overpitches, the power is not enough to overcome the drag created by the main rotor blades as they turn and this causes the main rotor rpm to drop. …
Loss of tail-rotor effectiveness (LTE) occurs when the tail rotor of a helicopter is exposed to wind forces that prevent it from carrying out its function—that of cancelling the torque of the engine and transmission. Any low-airspeed high-power environment provides an opportunity for it to occur. WebEfforts were directed to the failure of one of the main rotor blades that had apparently separated in the air. The apparent failure of a blade integrity monitor (BIM) system was …
