本文运用PAM-CRASH软件对吊挂进行了应急断离工况下的仿真研究。仿真结果标明:飞机在混凝土地面工况、0度仰角时可以成功的实现吊挂和发动机的安全抛离工作。仅通过改变销钉的尺寸很难保证在不同的工况条件下都实现成功的断离,还需要通过设计吊挂的结构以及吊挂与机翼或者吊挂与发动机之间的连接形式来实现。
This article uses PAM-CRASH software to simulate the suspension under emergency off condition. Simulation results show that: the aircraft in the concrete ground conditions, 0 degree elevation angle can successfully achieve the safety of the car and the engine to leave. Just by changing the size of the pin is difficult to ensure the success of the disconnect in different working conditions, but also through the design of the suspension structure and the suspension and the wing or the connection between the suspension and the engine to achieve.
