Experimental study of the propulsion system demonstrator with a central body

The paper presents results of testing the propulsion system demonstrator with a central body consisting of sixteen chambers of the low-thrust rocket engines positioned around the central body. Peculiarity of a propulsion system with the central body lies in the presence of self-regulation properties depending on the external environment pressure. Processes were analyzed arising in the propulsion system operation in various modes, including vibration state, thrust control, assessment of the structure natural vibration frequencies and analysis of the sound pressure.
