摘要
本文对实用的阻力系数飞行测定法进行了较系统的研究和应用分析。首先研究分析了现行测定法,从现行各法的公式,到推导出拓广公式,揭示各法的联系与数学实质,指出存在的问题和误差,以及设计测定方案时的注意事项。其次研究新的测定法,提出样条函数法。它能得出连续光滑的阻力系数曲线,有较高精度。
Practical flight-determinatlon methods for the drag coefficients of projectiles are systematically studied in this paper and its applications analyzed.The methods presently in use are studied first, from the formulas used to the further generalized cases. Connections between the various methods and their mathematical essentials are explicated and the existing problems and their errors, as well as the points to be noticed in designing their measurement schemes are enumerated.A new approach, the Spline Function Method, is then put forward. The method is capable of giving continuous and smooth curves, assuring a high precision.
