A laboratory stand for studying the effect of accelerations on the linear burning rate of solid rocket propellants comprising a DC electric motor (1) with an encoder (2), an energy storage module (8), an igniter power supply system (B), an electronic pressure measuring system (44) in a combustion chamber (22) and a solid rocket micromotor (A), characterized in that:
- the electric motor (1) is connected to the encoder (2), at the same time the electric motor is connected to a main shaft (5) by a bellows coupling (4), and an energy storage module (8) is placed on the main shaft (5),
- on the opposite side of the solid rocket micromotor (A) body (21) located on the main shaft (5) by a fastener (20) there is an igniter power supply system (B) mounted on the main shaft (5) comprising a power supply system sleeve (9) on which conductive rings (10) and insulating rings (11) are placed, terminated with a closing ring (12) and carbon brushes (16),
- the electronic pressure measuring system (44) in the combustion chamber includes a pressure sensor (36) located in a pressure sensor (36) socket (35) connected to the solid rocket micromotor (A) body (21) by means of a pressure measurement port (33),
- and, in addition, on the threaded end of the main shaft (5) there is a solid rocket micromotor (A) body (21) mount (20) containing the combustion chamber (22) with an internal collector groove (30) and the pressure measurement port (33) and a safety valve port (24) with a safety valve (26) together with an outlet socket (27) on the side of the solid rocket micromotor (A) body (21).
