Abstract:Based on the CCD image technology,this paper proposes a new kind of image contour aiming system which has realized image contour aiming of general optical instrument and modern digital instrument and resolved the problems of low automation degree,aiming accuracy affected by operator heavyly,intensive labour and not easy to be computerized etc.The construction and principle of the new system are presented and the data processing method of the image contour is analized emphatically in this paper. The experimental research has been done at last.

Abstract: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，表明此该有很高的计算精度。
