摘　　要：本文基于虚拟数值仿真技术建立了一种地面最小操纵速度(V MCG)临界性评估方法,并利用该方法对某型飞机不同重量、重心条件下的V MCG进行了仿真计算和评估,给出了进行V MCG试验时更为临界的重量、重心状态,可为其他飞机的V MCG临界性评估及V MCG飞行试验提供参考。Based on virtual numerical simulation technology,this paper establishes a criticality evaluation method for minimum control velocity on ground(V MCG),and V MCG of an aircraft under the conditions of different weight and center of gravity is simulated and evaluated by using this method.According to the evaluating results,the more critical weight and center of gravity in V MCG test is given,which can provide reference for criticality evaluation of V MCG and V MCG test of other aircraft.
