  • Shearing type ordnance venting device
    Patent number: 5035180
    Abstract: 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.
    Type: Grant
    Filed: March 28, 1984
    Date of Patent: July 30, 1991
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Nick L. Purcell, Joseph A. Schmidt, John A. O'Malley
  • Bending type ordnance venting device
    Patent number: 5035182
    Abstract: 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.

  • Drogue chute extraction
    Patent number: 4004764
    Abstract: 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.

  • Rocket nozzle multi function
    Patent number: 3952664
    Abstract: 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.

  • Load actuated electro-ignition circuit switch
    Patent number: 3949676
    Abstract: 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.
