Research on Aerodynamic Characteristics of Missile With Fins Under Low-speed Rotation
摘要
Abstract
In order to research the effect of low-speed rotation on aerodynamic characteristics of missile with fins,the flow-field around the missile with fins under small attack-angle and total Mach number was simulated by applying 3D unsteady N-S equations and slide mesh technology. The Army-Navy Basic Finner Missile was used for verifying the validity of the numerical simulation method. The results show that this method has high accuracy. The results under different Mach numbers,rotation speed and roll angle show that the longitudinal aerodynamic characteristics( lift,drag,pitching moment) is independent of spin. The average rolling-moment-coefficient is contantly proportionate to rotation speed,and the average Magnus-force-coefficient exhibits a nonlinear change with the rotation speed.关键词
