Report. Aberdeen proving ground, Maryland: Ballistic Research Laboratory. 1993. -157 p.A lumped parameter model is described in which the working fluid is assumed to decompose at a finite rate. The model is used to explore the sensitivity of maximum pressure and muzzle velocity to the failure of the rate of decomposition to keep pace with the rate of injection of energy. The influence of initial ullage as a desensitizing parameter is discussed, as is the use of the model as a means of determining the rate of decomposition given the history of plasma flux and chamber pressure.
Second, modifications to the XNOVAKTC Code (XKTC), a one-dimensional two-phase model of solid propellant gun interior ballistics, are described to represent a class of ETG devices in which a central ullage port is initially present. The code is used to explore further the ballistic consequences of nonuniform mixing. Finally, we present the formulation of a two-dimensional model of the ETG which is intended to address those processes which are outside the scope of the two simpler models.Другие работы Gough Paul S.:
