大型民用运输机全发失效后的飞行品质研究

Study on flying quality of large civil transport aircraft with all engines failed

详细论述了适航对民用大型运输机全发失效后的操纵系统及飞行品质的基本要求,讨论了全发失效后飞行品质的计算方法,并建立了飞机仿真模型。通过仿真计算和分析,验证了某型飞机全发失效后的适航符合性。该项研究对今后同类飞机的初步设计及适航符合性研究具有一定的理论指导意义和实际的工程应用价值。

The paper is to give details about the airworthiness authority’s basic requirements for the control system and flying qualities of a large civil transport aircraft after all engines fail,discuss the calculating method for the flying quality after all engines fail,establish the aircraft simulation model and verify the airworthiness compliance after all engines fail through the simulation calculation and analysis,thus providing certain theoretical and practical value to the similar aircraft in the preliminary design and airworthiness conformity study in the future.
