Analysis and modeling of stern clearance for aircraft landing
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 sta-bility mode are considered,and the stem 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 stem clearance are put forward.The results show that the model is suitable for the calculation of stem clearance of fixed wing shipbome aircraft with different sea condi-tions,different glide path stability modes,different optical basic angles and different ideal landing points.The research res-ults have certain reference significance for improving the landing safety of shipborne aircraft.
