Abstract: A test bench and technique for experimental investigation of thrust performance of a hybrid rocket motor are described. A configuration of a rocket motor operating on a solid fuel (polymerized unsaturated hydrocarbon C$_4$H$_6$) and gaseous oxygen is proposed. Measured results for motor thrust are given. It is demonstrated that injection of a swirled oxygen flow into the motor duct increases the thrust performance of this kind of motors.

Keywords: test bench, hybrid rocket motor, solid fuel, swirled oxidizer flow, thrust performance.
