典型舰载预警机复飞特性

Wave off Capability of A Typical Carrier-Based AEW

摘要:

舰载预警机复飞时,需要通过加大发动机推力提高飞行速度,从而增加其升力以使航迹下沉量减少,避免与舰尾相撞。在分析舰载预警机复飞准则的基础上,通过建立舰载预警机着舰复飞时的非线性动力学方程,计算分析了不同速度、不同下沉率时舰载预警机的复飞轨迹和复飞边界。仿真结果表明:适当的复飞决策距离和较大的发动机推力,可保证舰载预警机安全复飞。

Abstract:

When the carrier-based(Air Early Warning), AEW waves off,the engine thrust should be increased to achieve high velocity. And then the AEW has enough lift to avoid collision with the carrier. The wave off rules and decision system for wave off were established to improve the landing safety of the AEW. The wave off capability of the carrier-based AEW. Based on nonlinear flight dynamic model, the wave off track and bor. derline were analyzed according to the various velocity and sinking rate of the AEW was deal with. The results of the simulation in this paper showed that the proper wave off decision distance and the powerful engine thrust could ensure wave off safety of the carrier-based AEW.
