舰载机着舰航线侧方计时建模与分析

为了提高航母回收舰载机的成功率,针对舰载机在着舰航线的顺风飞行距离精准问题,进行侧方计时研究。考虑航母航行使下滑道距离变长,舰载机顺风边飞行时自然风速使地速变大,自然风对舰载机下降转弯产生漂移影响,基于飞行动力学理论,建立了舰载机在着舰航线上侧方计时的数学模型,并对此模型进行数值模拟分析。结论如下:本模型适合于不同重量、不同挂载、不同型号的常规起降方式的固定翼舰载机在着舰航线上进行侧方计时的计算。

Analysis and modeling of timing abeam on landing pattern for embarked aircraft

For the sake of successful recovery of the embarked aircraft, the research of timing abeam is carried out to solve the problem of accurate distance on the downwind leg in the landing pattern. The glide slope distance of the aircraft can be extended for the motion of the sailing carrier, the ground velocity of the aircraft is naturally increased on the downwind leg and the flight path of the aircraft could be shifted when turning down in the landing pattern because of the natural wind. The factors above have great impact on recovery and should be taken into consideration, thus a model of the timing abeam for the aircraft on landing pattern is presented based on the flight dynamics theories and the numerical analysis is conducted with the model. The numerical simulation suggests that the method of the model is suitable for different types of the conventional take-off and landing fixed-wing carrier aircraft with different weights and munitions, and reasonable results can be obtained through the model.
