摘　　要：提出了外挂副油箱中油液惯性特性的工程处理方法。在不同的油箱细长比、尺度比、油液深度和振荡频率下进行了系统的试验 ,得出了比较简单的油液在不同运动状态下的当量惯性系数。用这些当量系数对某型飞机进行了机翼 -外挂副油箱的动力特性计算 。An engineering approach to the determination of the inertia properties of the fuel in external tanks is presented. Systematic experiments were conducted for a range of slenderness and scale of the tank,depth of the fuel and vibration frequencies. Simple equivalent inertia coefficients of the fuel in different motions were obtained. Applying these coefficients to the calculation of the structural dynamic characteristics of the wing\|external tank of an aircraft, good correlation with the results of ground resonance tests was obtained.
