| 摘 要： | 根据动力学原理，建立了考虑起落架变形运动影响的飞机在甲板上的运动方程，提出了舰载飞机滑跃起飞斜板形状的最优化数学模型性能指标，约束条件和目标函数。其中，引进了罚函烽，把有约束的极值问题化为无约速的极值问题，并采用Ｐｏｗｅｌｌ法以及用商代替导数的ＤＦＰ方法进行了优化计算。计算结果表明，对斜板形状进行优化后，可以在很大程度上提高舰载机的斜板滑跃起飞性能。

| Abstract: | Based on principle of dynamics, this paper established dynamics equations of aircraft sking on deck taking into account landing gear deformation. Set up the optimum mathematical models of ski jump ramp (performance index, constraint and object function), and solved it by Powell method and DFP method. The results shows, after optimization, the ski jump take-off performance is improved to a great extent. |
