VARIABLE FLOW GAS GENERATOR

ROCKET ENGINEERING'S OBJECTIVE IS TO FORMULATE AND PRODUCE A CLEARBURNING, LOW FLAME TEMPERATURE PROPELLANT. THIS PROPELLANT WILL THEN BE USED IN AN ENGINE THAT WILL HAVE THE CAPABILITY OF BEING CYCLED A NUMBER OF TIMES FROM NORMAL OPERATING PRESSURES TO IDLE PRESSURES. THE PROPELLANT PORTION OF THE EFFORT WILL INCLUDE PURIFICATION OF THE AMMONIUM NITRATE OXIDIZER AND THE USE OF PRIMARILY ORGANIC CATALYSTS TO ELIMINATE METALLIC RESIDUES FROM THE EXHAUST PRODUCTS. THE THROTTLE PORTION OF THE EFFORT WILL KEY ON TWO DESIGNS: 1) A DESIGN EMPLOYING A SINGLE ORIFICE THAT MAY BE VARIED IN EFFECTIVE THROAT DIAMETER AND, 2) A SECONDARY ORIFICE THAT MAY BE OPENED AND CLOSED UPON COMMAND TO CONTROL CHAMBER PRESSURE.
