Patent number: 6869043Abstract: The center of pressure of a projectile is caused to move upon the occurrence of an event that changes the static margin, such as the jettisoning of a body previously attached to the projectile, as noted above. In particular embodiments, this is achieved by a flare disposed toward the rear of the projectile. The flare has petals that deploy from a first, stowed position to a second, deployed position upon the occurrence of the event. In the stowed position, the petals are aligned with the air stream, in order to minimize drag. In the deployed position, the petals project into the air stream in such a way as to move the lift center rearward. A slide ring within the flare has sufficient inertia that it shifts aft in response to an acceleration that occurs when the attached body and the projectile are separated from one another. The slide ring is linked to the petals in such a way that the petals are deployed by the displacement of the slide ring. Detents lock the slide ring in its displaced position.Type: GrantFiled: March 24, 2003Date of Patent: March 22, 2005Assignee: AT&T Corp.Inventors: John Daryl Carlyle, William Hall, Hartley Hughes King, Thomas Louis Menna, Lawrence Steven Romero

Patent number: 5551345Abstract: A smoke screen shell is provided having a rapidly burning decoy charge that generates a spontaneous fog and a slowly burning camouflage charge that generates a lasting fog. The decoy charge and camouflage charge are fired from a canister sleeve by an ejection charge. Upon firing, pressure from the ejection charge is communicated through a channel to a relief chamber positioned between the decoy charge and the camouflage charge. This results in an accelleration difference, causing a separation and slightly different trajectories, the decoy component accelerating at a higher rate. The decoy charge takes effect in the air prior to the camouflage charge. The collocation of the spontaneous fog and of the lasting fog essentially occurs in the target. The decoy charge and the camouflage charge land within a proximity at a target area such that a collocation occurs between the spontaneous fog and of the delayed lasting fog. The ignition and relief chambers, the channel therebetween, the charges, etc.Type: GrantFiled: November 3, 1994Date of Patent: September 3, 1996Assignees: Buck-Werke GmbH & Co., SM Schweizerische MunitionsunternehmungInventors: Norbert Wardecki, Herwig Feldmeier

Patent number: 5044281Abstract: A flare (1) for submarine use. The flare (1) is caused to be deployed from a submarine location where it will rise to the surface of the water because of its buoyant casing. A hydrostatic valve means (147) is provided within the casing and it opens when the flare is at or near the surface of the water to render said flare ready to project a flare composition (5) into the air. The hydrostatic valve means (147) is held inoperative by a latch mechanism (51) which is tripped as the flare is deployed from a firing tube at the submarine location. The flare composition (5) cannot be projected into the air until the flare (1) is within a range of vertical attitude determined by inclination means (13). The flare composition (5) cannot be projected into the air until the nose is above water. The flare (1) thus has a sensor (23) at its forward nose to determine that the nose is above the water.Type: GrantFiled: February 21, 1989Date of Patent: September 3, 1991Assignee: The Commonwealth of AustraliaInventors: Peter Ramsay, Brian W.

Patent number: 5003881Abstract: Illuminating flare has an igniter in which a two-part inertial mass is gud for relative aftward movement from a safe position to an armed position under launching forces. One part of the mass undergoes relative forward movement to an ignition position under parachute-opening, deceleration forces while the other part of the mass is restrained from moving as far forward as the first part. This separation of the parts of the mass releases locking balls to unlock a firing pin, which stabs a primer and initiates ignition of the flare. The primer is contained in a rotor, and as the mass traverses from the safe position to the armed position it rotates and the rotor rotates with the mass. In the safe position the primer is out of communication with an ignition passage through which ignition of the illuminant composition occurs. Rotation of the rotor as the mass traverses to the armed position places the primer in communication with the ignition passage where it remains until activated by the firing pin.Type: GrantFiled: August 7, 1990Date of Patent: April 2, 1991Assignee: The United States of America as represented by the Secretary of the NavyInventors: Stanley J.

Patent number: 4499829Abstract: An explosively separable casing including a cylindrical afterbody and a circular cover for one end of the afterbody is disclosed. The afterbody has a cylindrical tongue extending longitudinally from one end which is matingly received in a corresponding groove in the cover. The groove is sized to provide a pocket between the end of the tongue and the remainder of the groove so that an explosive can be located therein. A seal is also provided between the tongue and the groove for sealing the pocket from the atmosphere. A frangible holding device is utilized to hold the cover to the afterbody. When the explosive is ignited, the increase in pressure in the pocket causes the cover to be accelerated away from the afterbody.Type: GrantFiled: March 8, 1983Date of Patent: February 19, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventors: Albin K. Jacobson, Raymond E. Rychnovsky, Cornelius N. Visbeck

Patent number: 4335656Abstract: A signaling device to be launched underwater having a fuze body, a time dy element, an ejection charge and at least one carrier having a pyrotechnic composition attached to a parachute. The ejection charge is ignited by an electric squib which is detonated by voltage from a sea water battery. The battery is sealed from sea water until a valve opens to permit entry of water into the fuze body. An electronic deplay module is electrically connected between the sea water battery and squib to delay detonation of the ejection charge until the signaling device has assumed a stable vertical position at the water surface.Type: GrantFiled: July 31, 1980Date of Patent: June 22, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventors: Bobby D. Beatty, Russell D. Daniel, Billy J. Humerickhouse, Richard Williams

Patent number: 4333402Abstract: A projectile (1) containing particles of interference material is fired pneumatically from a launching tube (2). Compressed air, which is supplied to the launching tube and acts on the rear face of the projectile during firing, is conducted both to a loading chamber (19) wherein the air pressure is maintained even after the projectile has left the firing tube, and also via the loading chamber to an expansion chamber (20) in which, after a specific time-lag corresponding with a certain launch height on the trajectory of the projectile, an over-pressure builds up which causes the expansion of the chamber to be initiated with simultaneous expulsion of the interference material from the projectile. The compressed air may also be conducted to the chamber (10) in the projectile wherein the interference material is accommodated, tightly packed, in order to enhance the dispersion thereof.Type: GrantFiled: October 23, 1979Date of Patent: June 8, 1982Inventors: Sven Landstrom, Kaj Lundahl
