民用飞机失速特性研究

Stall Characteristic Investigation of Civil Aircraft

民用飞机失速特性和失稳特性的优劣直接影响飞机的安全性。从平尾修形、外侧缝翼缝道参数、内侧缝翼分离面等几个方面考虑,深入研究了失速特性和失稳特性的影响因素。本研究结果,为一般民用飞机失速特性设计提供切实有效的措施。

Stall characteristic and stability are vital for the security of civil aircraft. To detect factors of affect Stall characteristic and stability of aircraft, modifying aerofoil and area of the horizontal tail, slot parameter of outboard slat, separation face of inboard slat and fuselage are investigated. Based on research results, practicality and effective measurements are taken to improve aerodynamics characteristic of aircraft.
