The invention relates to a tailless layout large maneuvering flight course stability augmentation design method, belongs to the technical field of aircraft flight control, and solves the problems of control surface failure, multi-control surface coupling and sideslip angular velocity estimation error in the prior art. According to the tailless layout large maneuvering flight course stability augmentation design method, tailless layout course stability augmentation is carried out based on vector thrust, the course control torque generation mode is stable and reliable, the method is still effective during large-attack-angle flight, a control instruction is simple and single, and the problems of control surface failure and multi-control-surface coupling existing in a traditional pneumatic control surface are solved; when the sideslip angular velocity is estimated, a small-attack-angle hypothesis is not applied, lateral force estimation is performed through a lateral acceleration sensor, the sideslip angular velocity estimation method is suitable for a large-maneuver flight state of a tailless layout aircraft, and the problem of estimation errors of a common estimation method in a large-attack-angle flight state is solved.
本发明涉及一种无尾布局大机动飞行航向增稳设计方法,属于航空器飞行控制技术领域,解决了现有技术中舵面失效、多舵面耦合和侧滑角速度估计误差的问题。本发明的无尾布局大机动飞行航向增稳设计方法,基于矢量推力进行无尾布局航向增稳,其产生航向操纵力矩的方式稳定可靠,大迎角飞行时依然有效,控制指令简洁单一,避免了传统气动舵面存在的舵面失效和多舵面耦合问题;进行侧滑角速度估计时没有应用小迎角假设,且通过侧向加速度传感器进行侧向力估计,该侧滑角速度估计方法适用于无尾布局飞机大机动飞行状态,弥补了一般估计方法在大迎角飞行状态的估计误差问题。
