摘要: 支柱式沉浸水橇可降低水陆两栖飞机着水运动中的冲击载荷,其降载效果与水陆两栖飞机的运动参数有关。利用一般耦合算法对水陆两栖飞机着水运动进行仿真,并将结果与相关试验值比对以验证仿真方法的有效性。采用此方法研究了水橇着水角、飞机着水水平速度与飞机着水垂向速度对支柱式沉浸水橇降载性能的影响。结果表明:水橇着水角、飞机着水水平速度与飞机着水垂向速度对水橇降载性能影响显著,合理地控制水橇的着水角与速度,可获得良好的降载效果。

Abstract: The impact load of amphibious aircraft could be reduced efficiently by use of hydro-ski, and the load reducing effect of hydro-ski is obviously relevant with some motion parameters of the aircraft. General coupling method was used to simulate the water landing performance of an amphibious aircraft and the comparison between the calculated results and the model test ones was carried out to prove the effectiveness of the simulation method. The study analyzed the influence of hydro-ski touch attitude angle,aircraft touch horizontal velocity and vertical velocity on load reducing performance of the hydro-ski. Conclusion could be obtained that the influence of the above three factors on hydro-ski load reducing performance is relatively remarkable, and the impact load could be reduced more efficiently with the proper hydro-ski attitude angle and velocities.

Key words: amphibious aircraft, load reducing performance, hydro-ski, touch velocity, numerical simulation
