摘　　要：根据通勤类飞机适航条款CCAR23部的相关要求,分析了影响起飞性能的因素,提出起飞性能飞行试验测试需求;然后考虑全发起飞,以Y12×型机为例,采用"分段系数法"将连续的起飞过程划分为三个阶段,根据各阶段受力和运动特点建立不同阶段的数学模型并简化出相关特征参数;最后用符合数据相关性检查的特征参数进行起飞性能扩展计算,并以Y12×型机为模型给出了起飞性能飞行试验数据处理步骤,讨论了起飞性能的主要影响因素。Factors influencing takeoff performance was analyzed and the corresponding flight test requirements were put forward based on relevant airworthiness requirements CCAR23. Then,means of ＂ Subsection Coefficient Method＂ was adopted by considering takeoff with all-engines operative and taking aircraft Y12 × as an example,which divides a continuous takeoff phrase into three sections with different mathematical model because of their individual force and motion characteristics,and relevant characteristic parameters were developed by rebuilding and simplifying those mathematical model. Finally,these parameters which were identified and proved by data correlation check were used to extend the aircraft takeoff performance. Meanwhile,the steps for takeoff performance flight test data processing of aircraft Y12 ×was provided and the main influence factors on takeoff performance were discussed.
