TY - JOUR AU - J. Kapur PY - 2014/05/26 Y2 - 2024/03/29 TI - The internal ballistics of a high: low pressure gun JF - Defence Science Journal JA - DSJ VL - 7 IS - 2-3 SE - Research Papers DO - 10.14429/dsj.7.7560 UR - https://publications.drdo.gov.in/ojs/index.php/dsj/article/view/7560 AB - In the present paper the system of equations for the Non-Isothermal Model for a H/L gun has been developed and from this, the systems of equations for Isothermal and Non-isothermal models for orthodox gun and solid fuel rockets have been deduced. The Non-Isothermal Model for H/L gun has been integrated for a tubular charge. For isothermal model, reduction to an equivalent non-leaking problem has been discussed and the partially non-isothermal model has been integrated for the linear law. After all-burnt modification needed in Corner's energy equation is obtained. ER -
