着舰飞机舰尾净空建模与分析

Analysis and modeling of stern clearance for aircraft landing

飞机着舰下滑受航母运动影响较大。为了分析飞机着舰下滑时的舰尾净空,采用基于功率谱的航母运动模型,考虑光学助降系统中基本角和横摇角的设定,考虑光学下滑道稳定模式的类型,考虑飞机的钩眼距,建立着舰飞机的舰尾净空模型。以此模型开展飞机理想着舰下滑的仿真分析,讨论航母纵摇、横摇、垂荡等扰动运动对舰尾净空的影响,并提出应对舰尾净空减小的措施。结果表明,本模型适合于不同海况、不同下滑道稳定模式、不同光学基本角和横摇角的固定翼飞机在着舰下滑时进行舰尾净空的计算。研究结果对于提高飞机的着舰安全有一定的参考意义。

The landing glide of carrier based aircraft is greatly affected by the movement of aircraft carrier.In order to analyze the stern clearance of shipborne aircraft when landing and sliding,the aircraft carrier motion model based on power spectrum is adopted,the setting of optical basic angle and ideal landing point position and the type of optical glide path stability mode are considered,and the stern clearance model of shipborne aircraft landing is established.Based on this model,the simulation analysis of ideal landing and sliding of carrier aircraft is carried out,the influence of aircraft carrier pitch,roll and heave on ship stern clearance is discussed,and the measures to reduce ship stern clearance are put forward.The results show that the model is suitable for the calculation of stern clearance of fixed wing shipborne aircraft with different sea conditions,different glide path stability modes,different optical basic angles and different ideal landing points.The research results have certain reference significance for improving the landing safety of shipborne aircraft.
