An experimental study was made of the flowfield and the side force when a secondary fluid is injected into a supersonic nozzle. Main motor was a small solid ropellant rocket motor. Fluids studied were water, Freon-113 and oxygen. The flowfield around the secondary injection port was observed by means of a Schlieren system. Shape of shock wave generated by various injectants was measured and was compared to that by solid bumps. It was shown that the penetration height is dependent on the injection momentum, and that the shock angle is dependent on the injectant flow density. The side force was measured directly with a force transducer. Data on the relationships of side force to injectant flow rate and to momentum are presented. The effect of injectant property and the effect of injection condition are discussed.
