飞机气动载荷的获取一般要根据多项实验结果,经过飞行参数的仿真模拟,实验结果的处理等过程才能获得,而在飞机的初步设计阶段不可能进行大量的实验,但需要计算飞机的载荷和寿命。本文提出了一种利用数值模拟来确定基本气动载荷的方法,对于偏副翼的情况,用工程计算方法获得偏转引起的附加量,加到基本气动载荷上得到偏副翼时的气动载荷,该方法已用于某飞机型号设计。
Aircraft aerodynamic load acquisition generally based on a number of experimental results, through the simulation of flight parameters, the experimental results of the process can be obtained, and in the initial design phase of the aircraft can not be a large number of experiments, but the need to calculate the aircraft load and life. In this paper, a method of numerical simulation to determine the basic aerodynamic load is proposed. For the case of partial aileron, the aerodynamic load obtained when the aileron is added to the basic aerodynamic load is obtained by engineering calculation method. The method has been applied to the design of an aircraft model.
