首先建立了舰载机滚转时拦阻钩触舰碰撞和反弹过程的动力学模型。讨论了碰撞过程中飞机滚转角、下滑角的影响,分析了反弹过程中,拦阻钩缓冲器初始充气压力和油液阻尼孔大小对缓冲性能的影响。结果表明,随着滚转角的增大,拦阻钩横向受力骤增;随着飞机下滑角的增大,其弹起角速度和所受冲量呈线性增加。缓冲器油孔的缩小和充气压力的增大能减小拦阻钩的弹起高度和回落时间,改善其拦阻性能。
First of all, a dynamic model of the collision and bounce-back process of a ship-based aircraft when hovering on a carrier-based aircraft is established. The influence of roll angle and glide angle of the aircraft during the crash process was discussed. The influence of the initial inflation pressure of the blocking hook buffer and the size of the oil orifice on the cushioning performance was analyzed. The results show that as the roll angle increases, the lateral force of the barricade increases sharply. With the increase of the aircraft slip angle, the bounce rate increases linearly with the impulse. The reduction of the bumper hole and the increase of the inflation pressure can reduce the pop-up height and fall time of the blocking hook and improve the blocking performance.
