由炮膛磨损规律确定火炮初速减退量的方法

A Method for Determining the Decrement of Muzzle Velocity of Gun Base on the Law of Bore Wearing

根据炮膛磨损规律讨论了确定火炮初速减退量的方法,建立了火炮初速减退量与炮膛磨损规律关系的数学模型,利用该模型求出火炮的不同磨损曲线及每一条曲线所对应的初速减退量、曲线上各段的权重系数,用检测仪测出炮膛的磨损曲线后,即确定出火炮的初速减退量。

A method for determining the decrement of muzzle velocity of gun is discussed. The mathemat- ic models considering the relationship between the law of wear bore and the decrement of muzzle velocity are set up. The wear curves of the bore, the decrement of muzzle velocity correspondent to each curve and the weight coefficient of each section on the curve can be obtained by use of the established mathematic models. After the wear curve of the bore is measured by the detector, the decrement of muzzle velocity can be determined.
