直升机着舰降落操纵与动态响应研究

Research on manipulation and dynamic response of helicopter landing on ship

直升机在舰船上降落是一个非常复杂的过程,因此有必要对着舰降落阶段直升机的动态响应进行研究。首先,建立了直升机/舰船动态适配仿真模型。然后,通过UH-60A直升机的配平和操纵响应计算结果与飞行测量数据的对比,验证了仿真模型的准确性。最后,对直升机舰面降落操纵与动态响应进行了仿真计算与分析。研究结果表明:舰载环境对直升机着舰降落过程中的机体姿态变化有显著的影响;合理的操纵速率能控制直升机触舰时刻的机体姿态和角速率,减缓对甲板的冲击,保证直升机降落在限定着舰区域。

As it is a very complex process for helicopter landing on ship, it is nessary to research the dynamic response of helicopter during landing. Firstly, a helicopter/ship dynamic interface simulation model was proposed. Then, the results of trim and manipulation response of UH-60A helicopter were compared with flight test data to validate the proposed model. Finally, the simulation on manipulation and dynamic response of helicopter landing on ship was calculated and analyzed. The results show that the shipborne environment intensifies the variety of the body attitude angles in landing, reasonable push stick rates take advantages to the control of body attitudes and angular rates in touching on the deck, to reduce the impact on flight deck, and to ensure the helicopter landing on the limited landing zone.
