以某型舰载飞机为研究对象,建立舰载机拦阻着舰动力学模型,考虑了拦截索拉力、气动力和发动机推力。对模型进行数值求解,分析在拦阻过程中发动机推力及拦阻力对起落架缓冲器轴力的影响。结果表明:在舰载机着舰前0.3 s内,发动机推力和拦阻力对起落架缓冲器轴力影响很小;0.3 s后发动机推力会同时增大起落架缓冲器轴力峰值;拦阻力会增大前起落架缓冲器轴力峰值,减小主起落架缓冲器轴力峰值。
Taking a certain type of carrier-based aircraft as the research object, a model of ship-borne aircraft blocking the ship’s dynamics was established, and the cable pull, aerodynamic force and engine thrust were considered. The model was solved numerically to analyze the influence of engine thrust and blockage on the landing gear bumper force in the blocking process. The results show that the thrust and drag of the engine have little effect on the axial force of the landing gear bumper within 0.3 s before the landing of a carrier-based aircraft. After 0.3 s, the thrust of the engine will increase the peak value of the landing gear’s bumper force at the same time. Increase the front landing gear damper axial force peak, reducing the main landing gear shock absorber peak force.
