Effect of cyclic loads on structural damage of rocket propellant grain [PDF]
Rocket motor propellant grain, cast or bonded into the motor chamber or solid coating, is exposed to various loads during its service life. Rocket propellant is a viscoelastic material, whose mechanical properties strongly depend on temperature and ...

Combustion Modeling in Solid Rocket Motor Plumes
The thermo-chemistry of plumes emanating from solid rocket motors (SRM) is strongly influenced by hydrogen/oxygen/chlorine chemistry. These after-burning reactions have a significant impact onto the infrared signature, as well as on chemical and thermal loads within the propulsion system.

Modal Analysis of Solid Rocket Motor
How to avoid the natural frequency closing to the environment disturbance frequency is a very complicated problem in the solid rocket motor engine .Once the resonance phenomenon happened, Solid rocket motors will be subjected to a larger dynamic stress environment, resulting in engine damage.

Solid propellant rocket motor and method of making same [PDF]
A method is described for making a solid propellant rocket motor having a specific concavity formed within the fuel charge. A mandrel with an aperature wider than that of the casing is inserted within the motor casing and a solidifiable propellant cast ...

Solid rocket technology advancements for space tug and IUS applications [PDF]
In order for the shuttle tug or interim upper stage (IUS) to capture all the missions in the current mission model for the tug and the IUS, an auxiliary or kick stage, using a solid propellant rocket motor, is required.
