空中最小操纵速度VMC的确定是民机适航符合性验证的一项重要内容,其取值大小是飞机方向舵与发动机布局设计的重要依据之一.基于对飞机空中最小操纵速度的适航符合性验证试飞过程的物理认识,提出了初步确定VMC的数学仿真计算新方法.根据VMC验证试飞过程中驾驶员的操纵行为特点,建立了驾驶员的数学模型,进而构建了相应试飞任务的人机闭环飞行数学仿真模型.通过对飞机的VMC验证试飞过程进行准确的数学仿真模拟,可得到不同验证条件下的空中最小操纵速度.该方法对于指导飞机的方案设计与适航符合性验证试飞等都具有一定的理论指导意义与实际的工程应用价值.
The determination of VMC is one of the important contents of airplane airworthiness compliance verification, and the value of VMC is one of the important bases for aircraft rudder and engine layout design.According to the airworthiness compliance Verify the physical understanding of the flight test process and put forward a new method to determine the VMC mathematical simulation.According to the characteristics of the pilot’s manipulation in VMC during the flight test, the mathematical model of the pilot is set up, and the man-machine loop of the corresponding test mission Flight math simulation model.According to the accurate mathematical simulation of VMC flight test, the minimum flight speed under different verification conditions can be obtained.This method has the advantages of both flight design and airworthiness compliance flight test, Certain theoretical guidance and practical value of engineering application.
