摘要
介绍了在飞行中精确测量燃油量的方法。燃油量是液位的非线性函数 ,并与飞行姿态有关。将液面变换到机体坐标系中 ,再通过数值积分 ,可以精确计算出油箱中的燃油量。算例计算了椭球形油箱 ,将计算结果与理论计算结果进行了比较 ,表明此方法有很高的计算精度。
A accurate measuring method of fuel quantity in flight is introduced in this paper.The fuel quantity is a nonlinear function of the liquid level which is affected by the flight posture.Transforming the liquid surface into the on\|board coordinate,the fuel quantity in the tank can be calculated by means of numeral integral.As an example an oval\|shaped tank is calculated.Comparing the result with the theoretical result,it shows that this method has high calculation precision.
