舰载飞机着舰过程的参数适配特性

 舰载飞机着舰过程的参数适配特性对于着舰安全性有着重要的影响.基于着舰安全准则,研究了无风和平静海况下驾驶员视野、着舰下沉速率和拦阻距离对舰载飞机参数适配特性的影响,给出了一定初始状态下舰载飞机的着舰质量和着舰速度的适配包线,分析了影响最大着舰质量的因素并对适配包线的扩展方法进行了研究.结果表明,适配包线由最小着舰速度和最大着舰速度封闭而成.其中,最小着舰速度主要由驾驶员视野准则决定;对于最大着舰速度,当着舰质量较小时主要由着舰下沉速率准则决定,当着舰质量较大时主要由拦阻距离准则决定;最大着舰质量由拦阻系统性能和驾驶员视野共同决定.通过增大拦阻力、改善飞机的低速气动特性可以有效扩展适配包线范围,增加许用的最大着舰质量,但下滑角大小的改变对其影响不大.

Parameter Matching Characteristics of Carrier-based Aircraft During Deck Landing Process

The parameter matching characteristics of a carrier-based aircraft are important factors influencing landing safety.Based on the approach criteria,this paper studies the influence of the pilot field of view,the approach descending rate and the arresting distance on aircraft parameter matching characteristics under windless and calm sea conditions.The mat-ching envelope of the landing mass and speed on an initial state is given.The factors influencing the maximal landing mass and the methods of enlarging the parameter matching envelope are analyzed.The results indicate that the parameter match envelope is composed of the minimal and maximal landing speeds.The minimal speed is chiefly determined by the pilot field of view,while the maximal speed is primarily confined by the descending rate when the landing mass is small,and by the arresting distance when the landing mass is large.The maximal landing mass is mainly determined by the arresting system performance and pilot field of view.Increasing the arresting force and improving low-speed aero characteristics can increase allowable maximal landing mass with an enlarged envelope area,but changing the glide slope angle has little effect.
