基于安全准则的拦阻着舰参数适配特性研究

Parameter Matching Characteristics of Carrier-Based Aircraft Model during Landing Process Based on Approach Criteria

基于相关安全准则,对飞机着舰的开环参数适配特性进行了分析,推导出适用于着舰适配包线求解的数学解析式,进一步解算出载机质量与速度的适配曲面,并搭建了1套全量动力学数学仿真模型对其有效性进行了验证。在此基础上,分析了影响适配包线范围的多种影响因素。结果表明,适配包线范围由驾驶员视野、载机失速速度、拦阻装置特性及载机轴向过载等约束决定;最小着舰速度由驾驶员视野准则及载机特性决定,最大着舰速度则根据拦阻装置特性及轴向过载约束确定;减小下滑角或增大襟翼偏角可以有效提高载机低速着舰性能,增加舰船航速则可扩展最大着舰速度的范围。

Based on the approach criteria, the parameter matching characteristics of openloop parameters for carrier landing process of aircraft were analyzed, and then the matching envelope of the landing mass and speed was solved. In order to verify the validity of the massvelocity matching curve, a complete mathematical model was constructed. Several influencing factors of the parameter matching envelope are analyzed on this basis. The results indicate that the parameter matching envelope is decided by the pilot field of view （ FOV ） , stalling speed, characteristics of Mk73,axial overload and so on. The minimal engaging speed is determined by FOV and stalling speed, while the maximal engaging speed is determined by the axial overload and characteristics of Mk73. Landing performance of the carrierbased aircraft with the low speed can be effectively improved by decreasing the angle of glide. The result of increasing the angle of flap can give the same effect. Increasing the speed of carrier can extend the range of the maximal engaging speed. The proper value of these parameters should be obtained through tradeoff.
