Bhattacharyya PY - 2014/01/01 Y2 - 2024/03/29 TI - Piezometric Efficiency in an Orthodox Gun JF - Defence Science Journal JA - DSJ VL - 21 IS - 1 SE - General Papers DO - 10.14429/dsj.21.6229 UR - https://publications.drdo.gov.in/ojs/index.php/dsj/article/view/6229 AB - It has been shown that the muzzle velocity and the piezometric efficiency have greater values in case of a suitable moderated charge than in case of a single charge. The suitable moderated charge should consist of two components such that the pressure driving the shot remains absolutely constant throughout the period when the second component burns, the constant pressure being equal to the pressure at the burnt of the first component.
