The invention discloses a helicopter suspension anti-swing design method, and relates to the field of helicopter suspension design, and the method comprises the following steps: firstly, carrying out plane projection on a suspension system; assuming that the cargo swings at an angle at the lower end, and projecting again; determining an equivalent swing center of the cargo according to the two projection results; according to the relation between the distance delta r between the equivalent swing center and the vertex of the hanging system and the design parameters of the hanging system, the design parameters of the hanging system are adjusted, and delta r is made to be equal to the distance between the vertex of the hanging system and the gravity center of the helicopter; finally, the projection plane is adjusted, the steps are repeated, design parameters are integrated, the hanging system is designed according to the design parameters, and a hanging system product is obtained. According to the invention, by adjusting the design parameters of the suspension system, the negative influence of cargo swing on the helicopter can be reduced to the minimum or even eliminated, the burden of observers or pilots is reduced, and the flight safety is improved.
本发明公开了一种直升机吊挂消摆的设计方法,涉及直升机吊挂设计领域,包括:首先将吊挂系统进行平面投影;然后假设货物在下端摆动一个角度,并再次进行投影;进而根据两次投影结果,确定货物的等效摆动中心;然后根据等效摆动中心与吊挂系统顶点之间的距离Δr和吊挂系统的设计参数之间的关系,调整吊挂系统的设计参数,使Δr等于吊挂系统顶点到直升机重心的距离;最后再调整投影平面,重复上述步骤,并将设计参数进行整合,并以此进行吊挂系统的设计,得到吊挂系统产品;本发明,通过调整吊挂系统的设计参数即可将货物摆动对直升机带来的负面影响降到最低,甚至消除,减轻观察员或飞行员的负担,提升飞行安全。
