Mathematical simulation method to calculate air minimum control speed

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