Abstract

A numerical computational investigation of applying vortex generator to conventional figuration aircraft for directional stability improvement at medium angle of attack was conducted in this article. Results showed that vortex generator can put off the critical angle of directional instability from 22°to 29°, in addition, vortex generator also had a very little influence on the lateral aerodynamic characteristic. The flowfield was simulated under the condition of 4° angle of sideslip, Mach number of 0.0882, and Reynolds number of 0.466 million.
