TAIL ROTOR AUTHORITY CONTROL FOR A HELICOPTER

摘要

An apparatus for interconnection in a helicopter tail rotor control linkage(32) for changing the pitch of the tail rotor blades (36) inresponse to predetermined inputs is provided. The apparatus comprises alinkage member (46) having a variable geometry, an actuator (54),and a control unit (56). In a preferred embodiment, the control unit (56)utilizes a microcontroller (216) to monitor inputs correspondingto ambient air condition and automatically vary the maximum tail rotor pitchso as to provide maximum tail rotor authority over a rangeof altitudes.
