BALLISTIC PENDULUM FOR DEMONSTRATION OF OPERATING MODES OF A ROCKET ENGINE FOR SOLID FUEL

摘要

The task of the utility model is to expand the visual capabilities in the study of the processes occurring inside a solid propellant rocket engine through the implementation of the study of the influence of the geometric characteristics of the nozzle on the rocket engine thrust.;Changing the length of the nozzle and the cross-sectional area at the outlet at a constant pressure in the combustion chamber, the change in the thrust of the test engine 1 is experimentally determined from the angle of rotation and the length of the trace of a piece of chalk 12 on track 13 of the base 14, while investigating the influence of the geometric characteristics of the nozzle or the degree of its expansion , for the thrust of the rocket engine.
