<p>An apparatus for interconnection in a helicopter tail rotor control linkage (32) for changing the pitch of the tail rotor blades (36) in response to predetermined inputs is provided. The apparatus comprises a linkage 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 corresponding to ambient air condition and automatically vary the maximum tail rotor pitch so as to provide maximum tail rotor authority over a range of altitudes.</p> |
