Introducing students to the fundamentals of determination of rocket engines performance parameters. Introducing students to the design of rocket engines with liquid and solid propellants, as well as special units of liquid rocket engines. Fundamentals of thrust vector control of rocket motors. Introduction to methods of rocket engines testing.

After successful completion of the course, students should be able to: - define the performance parameters of rocket engines, - independently calculate the main structural parts of solid propellants rocket engines, - analyze all subsystems of liquid propellants rocket engines, - understand different concepts of the thrust vector control systems of a rocket, - apply the acquired knowledge in the field of experimental work on the tests of rocket engines.
