Thermally Initiated Venting Systems (TIVS)

Solid Rocket Motor (SRM) self-detonation is an unacceptable and highly dangerous occurrence. A system that would reduce the likelihood of this occurring would be highly beneficial to the Missile Defense Agency (MDA). Midé proposes to design a Thermally Initiated Venting Systems (TIVS) that will decrease the likelihood of SRM premature detonation in its canister. When the temperature and pressure inside an SRM canister rise too high, it can cause the SRM to detonate, possibly resulting in a loss of life. Midé has previously designed and flight qualified a Positive Pressure Relief Valve (PPRV) that is currently in use on the International Space Station. The valve will work on the same principal as the valve used in the space station. Given a rise in pressure or temperature inside the canister above a pre-determined level, the valve will be automatically be triggered open and quickly reduce the pressure inside the canister, helping to prevent premature detonation.
