摘要:

集群飞行器协同打击能增加整体作战效能,然而飞行器密集飞行面临机翼尾涡导致的飞行安全问题。针对集群协同打击过程中尾涡气动耦合效应会引起邻机产生过大诱导滚转力矩所导致的飞行安全问题,提出了一种机翼尾涡作用下能够满足飞行器集群飞行安全约束的协同打击策略。建立了飞行器集群密集飞行过程中机翼尾涡效应危险区域模型,并分析了尾涡诱导速度及其导致的诱导滚转力矩规律,在此基础上设计了基于改进人工势场斥力函数的尾涡危险区域规避机动策略;基于预估攻击时间一致性误差变量,设计了分布式时间协同制导律,保证所有飞行器的打击时间能够在有限时间内达到一致,并基于李雅普诺夫稳定性理论给出系统攻击时间误差的稳定性证明。仿真结果表明,所提出的考虑尾涡效应飞行安全约束的协同打击策略能够有效降低飞行器密集飞行时受到的尾涡干扰,既保证了飞行器集群飞行安全,又确保了集群协同打击的时空一致性。

Abstract:

The cooperative attack of clustered aircraft can increase the overall combat effectiveness, however, the dense flight of aircraft faces the flight safety problem caused by the wing wake vortex. Aiming at the aerodynamic coupling effect of the wake vortex in the process of cluster cooperative attack, which can cause the flight safety problem caused by the neighboring aircraft generating too large induced rolling moment, a cooperative attack strategy under the effect of wing wake vortex that can meet the safety constraints of the flight of the aircraft cluster is proposed. A dangerous area model of the wing wake vortex effect during the dense flight of aircraft clusters is established, and the induced speed of the wake vortex and its resulting induced roll moment law are analyzed, on which a wake vortex dangerous area avoidance maneuver strategy based on an improved artificial potential field repulsive function is designed. Based on the consistency error variable of the estimated attack time, the distributed time cooperative guidance law is designed, which ensures that the attack time of all the aircraft can reach the consistency within a finite time, and give a stability proof for the attack time error of the system based on the Lyapunov stability theory. The simulation results show that the proposed cooperative attack strategy considering the flight safety constraints of the wake vortex effect can effectively reduce the influence of the wake vortex interference during the dense flight of the vehicles, which not only ensures the safety of the flight of the aircraft cluster, but also ensures the temporal and spatial consistency of the cooperative attack of the cluster.
