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。
The strut-type immersion skid can reduce the impact loading of amphibious airplanes during watering, which is related to the amphibian’s motion parameters. The general coupled algorithm is used to simulate the water landing movement of amphibious aircraft, and the results are compared with the relevant experimental values to verify the effectiveness of the simulation method. Using this method, the influence of the water-skimmer angle, the horizontal speed of the waterplane and the vertical speed of the waterline on the drop-off performance of the strut-type immersible water-ski was studied. The results show that the influence of water-skiing angle, the horizontal speed of aircraft water and the vertical speed of water landing on the water-ski load-carrying performance are significant. The water-carrying angle and speed of the water-ski can be rationally controlled to obtain a good load-lowering effect.
