舰载飞机纵向逃逸性能仿真研究

Simulated Investigation for Carrier-Based Airplane Longitudinal Go-around Performance

摘要:

建立了舰载飞机的逃逸动力学分析模型,对飞机在不同着舰条件下的逃逸性能和起落架载荷进行了数值仿真。结果表明,着舰速度越大、发动机推力加速性越好,对飞机的逃逸越有利；舰艇运动会使飞机着舰点偏离理想着舰点并增大起落架载荷；舰尾流对逃逸性能的影响不大,但会使飞机着舰点偏离理想着舰点,不利于飞机的着舰安全。

Abstract:

A flight dynamic model of carrier-based airplane go-around was presented. Go-around performances and loads of landing-gear were simulated for various carrier landing conditions. Results show that larger approaching speed and engine-power acceleration are benefits for go-around performance. Due to carrier vertical and pitch motions, the landing point on deck may depart from the designated touch point (DTP), and the landing-gear loadings rise for some increments. Carrier air wake seems a little affect airplane go-around performance, but makes the landing point apart from the DTP which will affect the airplane landing safety.
