使用等效系统评价方法 ,根据数值计算结果分析了全权限电传操纵飞机从小迎角到失速迎角横航向飞行品质对于气动参数变化的灵敏度。结果表明飞行品质对操纵效能变化很灵敏 ,对横向气动导数变化又较航向灵敏 ,特别对于高增益、强调横向操纵飞机更为如此。同时建议飞控系统横航向通道随迎角调参 ,以确保在更宽的迎角范围内具有满意的飞行品质。 Based on the numerical results, the sensitivities of the flight quality of full-flight telemanipulator to changes of aerodynamic parameters from small angle-of-attack to mid-flight at stalling angle of attack are analyzed using the equivalent system evaluation method. The results show that flight quality is sensitive to changes in maneuvering performance and is more sensitive to lateral aerodynamic derivative changes, especially for high gain and emphasis on transverse maneuvering aircraft. At the same time, it is suggested that the flight control system should adjust the lateral direction of the tunnel to the attack angle so as to ensure satisfactory flight quality over a wider angle of attack.
