飞机滚转运动的控制余度与重构效能

论证了独立操纵的左右平尾使飞机滚动运动具有较大的控制余度，它增加了飞机正常飞行时的滚转力矩，在飞行中副翼出故障时可进行补偿重构，从而提高了滚动通道的余度等级和飞行的安全性，为减少滚转通道的余度配置提供了依据，通过针对操纵面失效和卡死两类故障的重构设计和仿真也证实了上述结论，同时，初步比较说明了自修复飞控系统在上述故障下的任务可靠性和基本可靠性均高于传统控制系统。

The Control Redundancy and Reconfiguration Benefit for an Aircraft's Roll Motion

In this paper it is discussed that the aircraft's roll axis has a control redundancy through the individual control tail surfaces. The roll moment is increased in the normal flight and the aircraft becomes reconfigurable when any failure of the ailerons appears.Then the safety, redundancy level and reliability of the aircraft can be increased. It allows a simplification of the redundant actuators. An example of an aircraft with 2 typical failures is illustrated and the above result is proved. At last,the reliabilities of the normal aircraft and the self repairing flight control system(SRFCS) under the above 2 failures are calculated and compared to prove the benefits of the SRFCS.
