    摘要: A flight control system for a helicopter having a main rotor and a tail rotor is provided. The flight control system includes an automatic rotor speed control being configured to transition the main rotor and the tail rotor between a high speed and a low speed based upon a plurality of received information without requiring any pilot action, the plurality of received information comprising height above ground level, knot indicated air speed, outside air temperature, barometric altitude, pressure altitude, density altitude, and an engine operational status.

    摘要: A bearing assembly which spaces bearing elements in an unequal relationship from one bearing element pocket to the next. The spacing minimizes the likelihood that the bearing elements will rest in the exact same location on an inner and outer race to reduce the potential for false brinelling. The net result is a decreased depth of false brinelling in any one location and an increased bearing life.
