计算了复合材料机翼的翼尖挠度和静气动弹性稳定性导数随海拔高度、速压及马赫数的变化。经研究发现:静稳定性导数随马赫数和速压的增大而减小,但其随马赫数的变化比较缓慢,而随速压的变化比较显著;翼尖挠度随海拔高度的升高逐渐变小,随马赫数的增加虽略有增长但比较小,随配平攻角的增加增长速度变化迅速。
The variation of wing deflections and static aerodynamic elastic stability derivatives of composite wing with altitude, velocity and Mach number were calculated. The results show that the static stability derivative decreases with the increase of Mach number and velocity, but its change with Mach number is relatively slow, but with the change of velocity pressure is more obvious. The deflection of wing tip gradually increases with altitude Smaller, with the increase of Mach number slightly increased but relatively small, with the increase of the angle of attack increases the growth rate changes rapidly.
