The simulation of interior ballistic performance of guns by digital computer program

Description

(Баэр Пауль Г., Франкл Джером М. Моделирование внутренней баллистики орудий с использованием цифровой компьютерной программы).— Aberdeen proving ground, Maryland. Ballistic research laboratories, 1962. – 66 p.When non-conventional guns are to be considered or when detailed design information is required, interior ballistic calculations become more difficult and time-consuming. To deal with these problems, the equations which describe the interior ballistic performance of guns and gun-like weapons have been programmed for the high-speed digital computers available at the Ballistic Research Laboratories. The major innovation contained in the equations derived in this report is the provision for use of propellant charges made up of several propellants of different chemical compositions and different granulations. Results obtained by the method described in this report compare favorably with those of other interior ballistic systems. In addition, considerably more detail is obtained in far less time. A comparison with experimental data from well-instrumented gun-firings .is also presented to demonstrate the validity of this method of computation.Contents: Introduction Interior ballistic theory Computation routine Discussion
