| 摘 要： | 对某型教练机以风洞试验数据为基础，考虑支架干扰修正、进气影响修正、喷流影响修正、雷诺数修正、寄生阻力、静弹性效应等对零阻作出修正，同时考虑高度修正、分离阻力系数、升致阻力因子、配平阻力增量的影响，最后得出用于实际飞行使用的Cy大于0.3非线性平衡极曲线，并作出极曲线修正前后对性能影响的比较。

| Abstract: | By consideration of correction for jamming,air inlet effect,jet flow effect,Reynolds number,parasite drag and static elastic effect,as well as the correction for altitude,separated drag coefficient,drag due to normal force,the effect of trim drag increment,the paper presents the correction for zero drag based on wind tunnel test data from certain type of aircraft.Finally,the Cy used in real flight be greater than 0.3 of nonlinear balance polar curve is obtained,and the paper makes out comparison for the effect on the performance between fore and aft correction for the polar curve. |
