TESTED, DISSIMILAR HELICOPTER STABILITY AUGMENTATION

摘要

- 24 -Tested, Dissimilar HelicopterStability AugmentationAbstractThe main roll and yaw axes of a helicopter havinga main rotor operative in response to cyclic and col-lective pitch commands and a tail rotor operative inresponse to pitch commands, include stability inputsto actuators which are selectively provided by ananalog channel, a digital channel, or one half byeach, the digital channels being manifested in adigital computer system which includes programs ofself-test, in-flight comparison between the inputsand outputs of corresponding analog and digital chan-nels, and ground tests of testable rate gyro inputsto the various digital and analog channels and theoutputs thereof.
