民用运输机全发起飞地面加速段计算方法研究

Research on AEO Takeoff Ground Acceleration Segment Calculation Method of Civil Transport Airplane

给出了起飞离地点的判断方法、建立了全发起飞地面加速段计算模型。以某民用运输机为例,对该机的全发起飞地面加速段数据进行分析计算,将计算结果与飞行试验所测的结果和设计方的理论推算结果进行了比较。结果表明,该计算方法正确可靠,而且比理论推算结果更加准确,可用于对设计方理论数据的修正,并可为其它飞机的全发起飞性能计算提供方法参考。

Based on the AEO takeoff ground acceleration segment calculation method of civil transport air plane, presents the unstick point estimation means, foundation the AEO takeoff ground acceleration segment compu tation module. Take some airplane for example, the AEO takeoff acceleration segment data is analyzed and cdculat ed, and the results are compared to the results measured during flight test. the calculation method is proved that is right and reliable , also more accuaracy than academic prediction results,this method can be used for amending the disigner＇ s conception datas, and for another airplanes＇ calculation.
