Influence of Booster on Aerodynamic Characteristics and Stability of Cruise Missile
In response to the influence of the shape of the booster separation chamber on the aerodynamic characteristics and static stability of cruise missiles,this article analyzes the mechanism of improving aerodynamic characteristics and stability by studying the stern contraction ratio and the shape design of the separation chamber,and forms the design concept of"increasing the stern contraction ratio and refine the curvature". The results indicate that the stern contraction ratio is the main factor af-fecting flow and aerodynamic characteristics. Increasing the stern contraction ratio can effectively reduce the area of local sepa-ration and improve flow conditions,which can reduce 1. 5％～2％ zero lift drag coefficient and improve 1％～3％ longitude static stability. Under a specific stern contraction ratio,the curve transition between the stern and the propulsion separation chamber has a certain improvement effect on resistance characteristics and static stability.
