Study on the effect of different nose tip on the yaw characteristics of aircraft at high angles of attack
摘要
Abstract
The test study on the effect of different nose tip on the yaw characteristics of aircraft at high angles of attack is introduced.It is shown that different nose surface roughness and nose tip have great influence on the yaw characteristics of aircraft at high angles of attack, with bluntness of nose tip, the magnitude of the side force and yawing moment decrease obviously.The small particle and minute asymmetry of the nose tip have great micro perturbation effect on the yaw characteristics and determinate the side force and yawing moment.关键词
