Abstract

The article is dedicated to the theoretical study of the non-stationary Combustion Velocity of Solid Rocket Fuel (CVSRF). To calculate the Internal Ballistic Characteristics (IBC) of solid fuel missile engines, combustion velocity laws are used. These laws represent stationary relationships between the Combustion Velocity of Solid Rocket Fuel (CVSRF) and initial pressure and temperature. These relationships are experimentally determined under “stationary” conditions, i.e., by burning fuel samples in stationary conditions.
