130mm固冲增程制导炮弹内弹道计算
针对固体燃料冲压发动机内弹道的特点，将内弹道的计算分为四个部分：1、圆锥绕流计算，包括求解激波角、穿越斜激波的计算、从斜激波后到锥面的等熵压缩过程的计算；2、进气道内部流动的计算，包括正激波前和正激波后的一文变截面等熵流动和穿越正激波的计算；3、燃烧室的计算，包括燃烧室热力计算、等截面加热管流计算；4、喷管流动的计算，包括收敛段的计算，扩张段的计算。
用VB编写了具有计算上述过程的软件，可以迅速得出四个部分所需的参数，对固冲压增程制导炮弹的相关设计提供指导和参照。

Title The Internal Ballistics Calculation of 130mm Solid fuel ramjet
Abstract
Solid fuel ramjet is a carrying fuel, the use of oxygen in the air of the new air-breathing combustion engine, This study 130mm solid fuel ramjet extended range projectile on the use of solid fuel ramjet, it can greatly improve the artillery range, and has a higher flight speed, thus shortening the whole trajectory of flight time, having broad application prospects. In this thesis, internal ballistics 130mm solid fuel stamping Extended Range Guided Munition were studied.
For within the solid fuel ramjet ballistic characteristics of the interior ballistics calculation is pided into four parts: 1, the conical flow around computing, including the solution of the shock angle, through the oblique shock wave calculations, from the oblique shock wave to the cone isentropic compression calculation process; (2) the calculation of the internal flow inlet, including the entropy flow and the calculation of normal shock through a normal shock dimensional change before and after the normal shock cross section; 3, the calculation of the combustion chamber, including combustion thermodynamic calculation, and other cross-sectional heating pipe flow calculations; 4, nozzle flow calculation, including the convergence of computing segment, the expansion segment.
VB prepared by the software has calculated the above processes, the required parameters can be quickly drawn into four parts, the relevant design solid fuel stamping Extended Range Guided Munition provide theoretical guidance and reference.
