| 摘 要： | 从外侧缝翼缝道参数、内侧缝翼分离面、缝翼与挂架间隙以及后缘襟翼缝道参数等方面考虑，分析了民用飞机失速特性和失稳特性的影响因素.结果表明，前缘缝翼根部和梢部细节对力矩特性有较大影响，缝翼挂架堵缝可提高升力，不影响力矩特性，调整襟翼偏角，可改变机翼有效弯度，不改变主翼分离特性.

| Abstract: | To detect factors of affecting stall characteristic and stability of aircraft, slot parameter of outboard slat, separation face of inboard slat and fuselage, slot between slat and pylon, and slot parameter of flap were investigated. The results indicate that, root and tip of slat may affect pitching moment characteristic, slot between slat and pylon may improve lift coefficient, but no contribution for pitching moment characteristic, and, adjusting deploy angle of flap may not improve separation characteristic on main wing, because effective camber of wing is not changed. |

| Keywords: | civil aircraft high lift device stall instability pitching moment |
