HIGH AUTHORITY STABILITY AND CONTROL AUGMENTATION SYSTEM

摘要

A method of increasing the control authority of redundant stability and control augmentation system (SCAS) actuators by utilizing feedback between systems such that one system may compensate for the position of a failed actuator of the other system. Each system uses an appropriate combination of reliable and unreliable inputs such that unreliable inputs cannot inappropriately utilize the increased authority. Each system may reconfigure itself when the other system actuator fails at certain positions so that the pilot or other upstream input maintains sufficient control authority of the aircraft.

1. A rotary aircraft, comprising:
a fuselage; a rotary system carried by the fuselage; a control input; a first flight control computer carried by the fuselage; a second flight control computer carried by the fuselage; a first actuator commanded by the first flight control computer; a second actuator commanded by the second flight control computer; and a third actuator; wherein an output of the first actuator is summed with an output of the second actuator and summed with the control input for manipulating the rotary system in a first axis by controlling the third actuator.
