舰—机适配条件对舰载机滑跃起飞性能的影响

Influence of Carrier-Aircraft Adaptation Condition on Performance of Carrier-Based Aircraft Ski-Jump Takeoff

针对不同舰—机适配条件下舰载机起飞安全性的问题,建立了飞机滑跃起飞动力学分析模型,用数值方法分析了飞机起飞质量、甲板参数、舰船航行速度等因素对飞机滑跃起飞性能的影响。仿真结果表明:舰载机起飞质量增大会减小其离舰爬升率;平直甲板越长或斜甲板出口倾角越大,离舰爬升率越大;但是出口倾角太大时,会使飞机离舰迎角超出限制;增大舰船的行驶速度,可以缩短舰载机起飞所需甲板的长度。

In order to research the security of the carrier-based aircraft takeoff in different carrier-aircraft adaption condi-tion, a dynamic model of aircraft ski-jump takeoff was presented. And the influences of takeoff weight, deck parameters and carrier speed were analized by numerical simulation. The simulation results showed that the increase of takeoff weight could induce the decrease of aircraft’s rate of climb, and the extend deck length and ramp angle could help to increase the aircraft’s rate of climb. But too large ramp angle could make the aircraft’s angle of attack exceed its limit. The heigher car-rier speed contributed to a short deck length of aircraft ski-jump takeoff.
