针对直升机-舰船动态配合研究的需求,开发了一种舰载直升机-舰船动态配合耦合模型。该模型以直升机飞行动力学模型为主体,包括了几个子系统模型,同时考虑了子系统间的相互影响与耦合作用。以UH-60A直升机与某型舰船的动态配合为例进行了着舰降落仿真研究。结果表明:流场、舰效和舰船运动等舰载因素加剧了直升机着舰过程中的机体姿态变化,增大了触舰速度,加大了着舰风险。
Aiming at the demand of helicopter-warship dynamic coordination research, a ship-helicopter-warship dynamic coupling model was developed. The model is based on the helicopter flight dynamics model and includes several subsystem models, taking into account the interaction and coupling between the subsystems. Taking the dynamic coordination between a UH-60A helicopter and a certain type of ship as an example, a landing landing simulation study was carried out. The results show that the ship-based factors such as flow field, ship effect and ship movement aggravate the attitude change of helicopter during the process of landing, increasing the speed of the ship and increasing the risk of landing.
