舵面故障情况下推力矢量在飞艇中的应用研究

推力矢量控制技术是一种先进的推力控制方案,将其应用于飞艇的飞行控制,可以在飞艇低速气动舵面失效或者舵面故障等特殊情况下,辅助甚至替代舵面控制飞艇正常飞行。建立了考虑推力矢量的飞艇数学模型,增加了飞艇的控制余度,分析了飞艇常见的舵面故障形式,研究了推力矢量对飞艇舵面故障的补偿和重构。仿真结果表明,推力矢量可以在舵面故障情况下对飞艇进行有效的控制,提高飞艇飞行的安全性和可靠性。

The Application Of Thrust Vector In Airship With Control Surface Failure

Thrust vector control technology is an advanced thrust control program,and can help or even replace control surfaces to accomplish certain flight purpose when applied in airship.In this paper,the mathematical model of airship with thrust vector was establishied, common failure forms of control surfaces was analysed and the compensation and reconfiguration of thrust vector against control surface failure was researched.Simulation result shows that the thrust vector can control airship with control surface failure effectivelly ,as a result,the security and reliability of airship was enhanced.
