An ordnance venting system is provided to reduce the danger of explosion in rdance items exposed to fires and includes an ordnance item having a number of holes in the ordance casing, each hole being covered by a bimetallic patch which will deform when subjected to high temperatures, and each patch being attached by means such as brazing, soldering or adhesive bonding.

Bending type ordnance venting device

An ordnance venting system is provided to reduce the danger of explosion in rdnance items exposed to fires and includes an ordance item having a number of holes in the ordnance casing, each hole covered by a metallic patch having a different differential expansion in relation to the casing to provide shearing forces when subjected to high temperatures, and a means of attaching the patches to the casing over the holes.

Shearing type ordnance venting device

A drogue parachute deployment system for an ejection seat comprises a dro parachute mounted in a bag on the seat, a rocket motor, and a tow line attached between the parachute and the rocket motor. Upon firing of the rocket motor, the bag is caused to rip and the parachute is deployed.

Drogue chute extraction

A rocket motor assembly for a rocket motor utilized for towing a load or racting an aircrew member from an aircraft. The rocket motor is formed in two separate sections, a casing portion and a unitary nozzle igniter housing portion. The nozzle and igniter housing portion has a circumferential portion that mates with the internal surface wall of the casing portion. A seal and fastener holds the housing in place whenever the rocket motor is assembled. A shackle secured to the igniter mechanism is fastened to a tow line extending to a load to be towed.

Rocket nozzle multi function

An igniter mechanism for a rocket motor utilized for towing a load or extting an air crew member from a disabled aircraft. The mechanism operates whenever a sufficient force is exerted on the tow line to shear a pin allowing closure of the switch. Electrical energy coupled to the switch is conducted to a squib which ignites a charge to cause ignition of the rocket motor propellant. The electrical switch mechanism can only be actuated by a predetermined pulling force on the tow line thereby causing the electrical contacts to be brought positively together.
