摘要: 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.Abstract: The determination of the air minimum control speed VMC is an important content in the civil aircraft airworthiness compliance verification. The value of VMC is one of the vital bases to design the rudder and engine layout of an aircraft. Based on the physical understanding of the VMC airworthiness compliance flight test, a method to calculate VMC by mathematical simulation was proposed. According to the behavior characteristics of the pilot in the VMC flight test, the mathematical pilot model was established. Then, the pilot-aircraft closed loop flight simulation model for the VMC flight test was set up. Based on the accurate mathematical simulation of the VMC flight test, the value of VMC under different test conditions can be obtained. The method to calculate VMC proposed has important theoretical and practical value to guide the aircraft design and airworthiness compliance flight test.
