Effect of cyclic loads on structural damage of rocket propellant grain [PDF]

open access: yesScientific Technical Review, 2019
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 ...

Evaluation of elastomeric heat shielding materials as insulators for solid propellant rocket motors: A short review

open access: yesOpen Chemistry, 2020
This review addresses a comparison, based on the literature, among nitrile rubber (NBR), ethylene-propylene-diene-monomer rubber (EPDM), and polyurethane (PU) elastomeric heat shielding materials (EHSM).

Burning Rate Enhancement Analysis of End-Burning Solid Propellant Grains Based on X-Ray Real-Time Radiography

open access: yesInternational Journal of Aerospace Engineering, 2020
Unexpected pressure rise may occur in the end-burning grain solid rocket motor. It is generally believed that this phenomenon is caused by the nonparallel layer combustion of the burning surface, resulting in the increase of burning rate along the ...

Combustion Modeling in Solid Rocket Motor Plumes

open access: yes, 2019
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.

Solid propellant rocket motor and method of making same [PDF]

open access: yes, 1977
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]

open access: yes
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.

Assessing the Metrological Reliability of Static Firing Tests of Rocket Motors Through the Evaluation of Thrust and Total Impulse Measurement Uncertainty

open access: yesApplied Sciences
A solid propellant rocket motor is a propulsion system used in missiles and rockets that burns a propellant, typically composed of a mixture of fuel and an oxidizer, to generate the thrust necessary to propel the vehicle.
