翻译后摘要：在飞机动力学的问题，如稳定性和响应的刚性飞机可能会受到影响的油箱中的燃料运动。导弹方面也可能出现这种问题。本文研究了燃料对矩形贮箱作平移、俯仰和偏航简谐运动的响应。得到了自由表面的形状以及力和力矩的值。利用力和力矩的表达式，构造了与燃料等效的简单力学系统。这些系统以与燃料相同的方式对罐壁的运动做出响应，产生相同的力和力矩。借助于这种机械类比，整个动力系统可以用任何所需的过程来处理。
Abstract : Problems in aircraft dynamics such as stability and response of the rigid airplane may be affected by fuel motion in the tanks. Such problems might also arise in connection with missiles. In this report the response of the fuel to simple harmonic motions of a rectangular tank in translation, pitching and yawing is studied. The shape of the free surface and the values of forces and moments are obtained. Using the force and moment expressions, simple mechanical systems equivalent to the fuel are constructed. These systems respond to motions of the tank walls in the same fashion as the fuel, producing identical forces and moments. With the aid of this mechanical analogy the complete dynamic system can be handled by any desired process.
