Study on Application of High-aspect-ratio Axial-symmetrical Aerodynamic Configuration
摘要
Abstract
In order to study the high-aspect-ratio axial-symmetrical aerodynamic configuration of small am-munition,the lift-drag characteristics of the aerodynamic configuration and the force on elastic wing were obtained by mathematical simulation and wind tunnel test. Taking into account the effect of the elastic wing on the aerodynamic load, the effects of the wing turning over 5° and 10° on the whole spring resistance were analyzed. Aiming at the characteristics of the folding wing assembly,the impact of the de-ployable mechanism on the aerodynamic characteristics of the projectile was analyzed. The results show that the effect of the wing turning over on the lift force is great, and the effect on drag force can be neglected. The non synchronization of missile wing has little influence on the aerodynamic characteristics of the whole missile. Based on the operational mission of the small unmanned aerial vehicle,the use of the high-aspect-ratio axial-symmetrical aerodynamic configuration on the UAV ammunition was proposed.关键词
