Abstract
A system is disclosed for relieving excessive pressure within a combustion chamber of a spin-stabilized, jet-propelled missile launching system. An annular passage surrounds an exhaust nozzle, the passage being in communication with the chamber. A unitary valve ring closes the passage. Frangible pins hold the unitary valve ring in its closing position. An exhaust vent slaving cavity is provided for capturing the unitary valve ring upon rupture of the frangible pins. Exhaust vent ports communicate the slaving cavity with atmosphere, whereby the slaving cavity operates to capture the entire unitary valve ring bodily upon rupture of the frangible pins in response to excessive pressure within the chamber to relieve the pressure as the exhaust vent ports exhaust the chamber.
