Abstract: Based on the aerodynamic configuration of New Javelin light antitank missile, a series of wind tunnel experimental model was designed with the component build-up method. Six-component force experiments were conducted for Mach numbers ranging 0.3 — 0.5 and angles of attack — 1° — 15°. The experimental results show that, while the wing number increases from four to eight, the experimental configurations are static stabilization and the normal force and normal overload increase more than 40 %，but the increase of zero-lift drag is under 5 % . The experimental results also indicate that eight wing configuration maybe is the best configuration.
