Wind tunnel test research of lateral-directional control effect of plane-symmetric hypersonic vehicles

  • 摘要: 面对称高速飞行器在大攻角机动过程中存在气动耦合性强、稳定性弱及非线性、非定常特征显著的问题,这给飞行器气动特性研究、控制系统设计和地面验证提出了新的挑战。本文针对新型高速飞行器控制特性评估需求,以面对称高速飞行器模型为研究对象,在1 m量级高速风洞进行了虚拟飞行试验,设计了低阻尼滚转-偏航两自由度运动机构、小型化舵控装置和高性能无线测控系统,成功完成了多种控制策略下的倾斜转弯(Bank-to-turn, BTT)机动试验,实现了控制特性评估与控制律对比、验证,为飞行器气动和飞控设计提供了可靠的试验依据和验证平台。

     

    Abstract: Plane-symmetric hypersonic vehicles suffer from high aerodynamic coupling, weak stability and strong nonlinearity problems during large-angle-of-attack maneuvering flight, which poses a challenge to aerodynamic characteristics research, control system design and ground validation. To meet the coupling characteristic evaluation requirement of next-generation hypersonic vehicle, an innovative virtual flight test system has been established for the first time in a 1m-scale high-speed wind tunnel. The system incorporates customized components such as a low-damping rig, a compact helm gear, and a high-performance control module. Utilizing the Bank-to-Turn control strategy, the test system has successfully simulated the vehicle's maneuvering flight under three control laws in the hypersonic wind tunnel. The test system offers a suitable solution for the coupling characteristics evaluation and control law validation, and provides a universal verification platform for aerodynamic design and flight control optimization.
