Intracameral processes in solid propellant rocket engines of various designs are considered. Methods of calculation of intraballistic parameters, stress-strain state of charges rigidly fastened to the housing and solid-propellant rocket engine housings are described. Methods for studying the processes of solid fuel combustion and experimental development of solid propellant rocket engines are analyzed. The book is designed for specialists whose professional activities are related to the development of solid propellant rocket engines and its structural units. It can be useful for graduate students, students and university teachers.
