SYSTEM AND METHOD CONTROLLING PRESSURE OSCILLATION HYDRODYNAMICALLY GENERATED IN SOLID PROPELLANT ROCKET ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a system passively controlling pressure oscillation hydrodynamically generated in a solid propellant rocket engine 61. SOLUTION: This solid propellant rocket engine having a body 62 storing a loading material 63 of solid propellant is characterized in having, at least, a single inclusion 100 laterally positioned to the flow direction E of combustion gas of the solid propellant in the body of the rocket engine. The inclusion is provided with an opening part 101 having a non-axisymmetrical shape for producing a three-dimensional effect to the flow and preventing the formation of a turbulent flow mode in the rocket engine. Such a system can be applicable to an existing rocket engine. COPYRIGHT: (C)2004,JPO
