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。
According to the relevant requirements of CCAR23 part of Commuter Airworthiness Clause, the factors that affect the take-off performance are analyzed and the test requirements of take-off performance flight test are proposed. Then, considering the full take-off, taking Y12 × type machine as an example, "The continuous take-off process is divided into three stages, according to the various stages of force and movement characteristics of different stages of the mathematical model to establish and simplify the relevant characteristic parameters; Finally, consistent with the characteristics of the data correlation check takeoff performance expansion calculation, Taking the model of Y12 × as a model, the flight test data processing procedure of take - off performance is given. The main influencing factors of take - off performance are discussed.
