本文介绍了航空炮射弹道的一种近似求解方法。过去,航空炮射弹道(又称航空射击弹道)的简化求解方法,一直沿用查弹道函数表的“表解法”,即:事先把某些弹道参量的函数关系,经计算后编制成《空中射击弹道函数表》,求解弹道诸元时,用简化解析式经查上述《函数表》,再经线性插值而得。本文介绍一种既可省去编算、查弹道函数表与插值等大量工作,又可应用於火控计算机的“直接解析式方法”。它是将弹丸的空气阻力系数C_(xo)与马赫数M的表格函数事先处理成函数解析式,然后积分求解直接得到求解弹道诸元的解析式。
This paper presents an approximate solution to airborne projectile trajectory. In the past, the simplified method of solving aeronautical projectile trajectory (also known as air-launched ballistic trajectory) has been to use the “table solution” of the ballistic function table, that is, the function relationship of some ballistic parameters is calculated in advance, Ballistic function table “, when solving ballistic elements, with a simplified analytical method through the above” function table “, and then by linear interpolation derived. This paper introduces a ”direct analytic method" that can save a lot of work such as calculating and checking ballistic function tables and interpolation, and can also be applied to fire control computer. It takes the form function of air resistance coefficient C_ (xo) and Mach number M of the projectile in advance as a function analytic formula, and then obtains the analytic formula of the solution of the ballistic elements directly by integral solution.
