某型无人机滑跃起飞性能分析

Research on the Ski-Jump Takeing off Performance for a UAV

摘要:

针对舰载无人机滑跃起飞性能参数的选择问题,文章采用 Matlab/Simulink建立了滑跃起飞模型,分析了不同推重比、停机角、甲板风速、纬度和环境温度时无人机滑跃起飞性能的变化情况。计算结果表明:停机角和甲板风速对起飞性能影响大,应着重关注；低纬度地区比中纬度地区需要更大的推力保证起飞安全。文章结论对后续 无人机的滑跃起飞试验有借鉴意义。

Abstract:

For selection problem of carrier-based unmanned aerial vehicle’s (UAV) ski-jump taking-off performance pa.rameters, in this paper, a model with Matlab/Simulink was established, the performance change of the UAV under differentsituation of thrust-weight ratio, ground angle, wind-over-deck speed, latitude and ambient temperature was analyzed. Theresults showed that firstly ground angle and wind-over-deck speed had a greater effect on takeing-off performance, somore efforts should be made on these two aspects, and secondly low latitudes needed more thrust than high latitudes to en.sure the safety of taking-off. The results could be used as reference for the future ski-jump testing of the UAV.
