According to the results,the changes of angle of attack and stabilizer angle for a RLSS aircraft in trimming and its basic performances are calculated.
讨论了某机放宽纵向静稳定度后,重心后移量对飞机纵向气动参数的影响,以及由此所引起的飞机配平迎角、平尾偏角及基本飞行性能的变化,为我国未来民机实施放宽纵向静稳定度功能的验证提供了理论依据。
5) Tail fin deflection
尾翼偏角
6) boattail angle
尾锥角
1.
On condition that the shape of front-body of projectile is fixed and the air density is constant, a method is put forward to determine the optimal boattail angle with muzzle Mach number and vertex point Mach number of trajectory.
在弹丸前体外形和外界大气密度不变的条件下，提出了利用弹丸炮口马赫数和顶点马赫数确定旋转弹丸最佳尾锥角的方法。
2.
On condition that the front body shape of the projectile is unchangeable,a formula is obtained for determining the relation between the optimum boattail angle and the supersonic flight region.
用近似方法分析了超音速弹丸尾部和底部流动,在前体外形不变的条件下,得到了最佳尾雏角与弹丸超音速飞行区间的关系式,质点弹道计算结果表明,最佳尾锥角的确定方法是合理和有效的,而且尾锥角选取的差异将会引起射程等弹道参量的显著变化。
