Patent number: 5445078Abstract: Payload delivery of a payload compartment containing a delivery device is initiated by a suitable fusing device which ejects the delivery device from a payload section by firing a gas generator in the section base to propel the delivery device forwardly, thereby shearing retaining pins and ejecting the delivery device from the payload section. The fusing device concurrently fires a time-delayed mechanism leading to a second gas generator in the center of the delivery device. The gas generator ignites after the chaff dispenser is clear of the payload section. The ignition reaction pneumatically blows chaff (e.g. metallized dipoles) out of wrapped bundles, leaving the wrapper bonded to the delivery device and disseminating the chaff in a cloud of hot gas and air turbulently mixed in the wind shear occurring in the wake of the delivery device. The delivery device survives the dispensing and dissemination processes without losing structural integrity. Thus, no harmful debris is ejected into the chaff cloud.Type: GrantFiled: July 12, 1994Date of Patent: August 29, 1995Assignee: Universal Propulsion Company, Inc.Inventor: Frank A. Marion

Individual targets can then, without necessitating the technological demands for evaluating a target signature, be easily found by guided projectiles or missiles possessing target seeking devices which are directionally oriented towards the radiation energy of the marker, and homed thereon precisely targeted even when the target objects are already dispersed in a looser formation over a larger area.Type: GrantFiled: February 11, 1988Date of Patent: September 19, 1989Assignee: Diehl GmbH & Co.Inventors: Bernhard Trosky, Clemens Wolfschmitt

Patent number: 4722282Abstract: A payload-carrying projectile 1 includes a sensor 16 and a sensor carrier 15 disposed in a launch-resistant manner in a recess 14 in the tail section 11 of the projectile 1. After impact of the projectile, which is stabilized by extendable vanes 12, in the target area, where it may penetrate the ground as necessary, the object is to deploy the sensor from its protected position inside the projectile 1and to place it as high as possible above the surface of the ground. For this purpose, the sensor 16 is connected with a concertina bellows 15 which for its part leads into a reservoir 13a which is disposed in the projectile, and which is filled with polyurethane foam mixed with a propellant gas under high pressure. The connection of the reservoir 13 with the concertina bellows 15 is made via a valve 13c which is regulated by an electronic control element 13a containing, for instance, a timer switch.Type: GrantFiled: November 10, 1986Date of Patent: February 2, 1988Assignee: Rheinmetall GmbHInventors: Reinhard Synofzik, Rolf Hellwig

Patent number: H770Abstract: A tracer training bullet which can be assembled into a conventional cartre case and fired in a conventional M2 machine gun is disclosed. The bullet consists of a main body of relatively low strength material which is segmented so that, if not restrained, it will bend under the centrifugal rotational force imparted to the segments by the spinning action of the projectile when fired. The bending of the projectile segments away from their central axis is ordinarily prevented by a retainer in the form of a spider. The spider is made of a relatively low temperature melting material, preferably aluminum, having a given thermal mass. The burn of the tracer material during the flight of the bullet toward a target weakens the retainer to the point of rupture after the bullet has travelled a given distance toward a target position. After the target position is passed, the securement member is destroyed by the high temperature burning action and the segments of the projectile bend or flex apart.Type: GrantFiled: August 11, 1989Date of Patent: April 3, 1990Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Roy W. Kline, Sung-Kwong Chung
