Otto K. Heiney. Analytic and experimental interior ballistics of closed breech guns
Report. Air force armament laboratory. 1969, - 46 p.
A closed breech incremental interior ballistic formulism is presented along with a Fortran '» computer program which utilizes the system. Typical input and output data, both plotted and tabular, are included. A unique characteristic of the system is that it avoids the inaccuracies associated with approximate analytic propellant regression expressions in that regression rates are determined by a tabular routine. Various pressure gradient expressions are investigated. Correlation of the mathematical model and computer predictions to experimental device firings are presented. A shock-driven deflagration effect which may be initiated during the ignition transient is described and a postulated correlation parameter defined.
