摘要:
A tactical missile includes a heat pipe connecting heat sources with heat sinks within the missile. The system includes a removable external heat dissipation device that connects to the heat pipe while the missile is being tested or reprogrammed. The external heat dissipation device draws heat out of the heat pipe and so maintains the electronic components acceptably cool during extended testing or reprogramming. During the relatively short tactical flight, the heat pipe transfers heat from the electronic components to the heat sinks within the missile. The high heat transfer rate of the heat pipe enables elements such as structural members and propellant to be used as heat sinks, elements not heretofore incorporated into thermal management of the heat generating electronic components.

A projectile for missile intercepting machine guns or the like having a hollow projectile body which includes a front end part having an inside thereof shaved taperingly to make a wall thickness becoming smaller and smaller toward a front end, thereby forming a thin wall part. An outer edge of the front end of the thin wall part is cut to form an acute angle part. The acute angle part of the projectile body is adapted to bite and stick into a flying object or the like to surely shoot down the latter.

A smooth bore barrel system utilizes an ammunition round capable to provide the projectile, covered with predetermined usually spiral grooves (44) and lands (42) congruently engaged in the rifled by the same manner inner surface (30A) of the cartridge case (30). When fired the rifled cartridge case serves as a short disposable rifled barrel spinning the projectile. A front short non-rifled part (40B) of the cylindrical portion of the projectile is extended into the smooth bore barrel (20) having sliding fit within. Alternatively, spinning momentum is provided by having the grooves tapering to narrow channels extended through the short cylindrical portion of the projectile forming jets (48), which rotate the projectile by jet propulsion forces. Spinning momentum is gained by two independent approaches which effect could be combined or used separately.
摘要:
A hardened subminiature telemetry and sensor system for a ballistic projectile having a radome, antenna, steel insert, S-band transmitter circuit board, data recorder, sensor or measurement device and battery. The entire assembly is contained in such a way that the assembly can be threaded into the existing tracer well of a kinetic energy projectile.
摘要:
A device including a ring for linking a case and a projectile carrying a sealing band having a rear skirt providing low pressure sealing and a front rib lodged in a first groove in the projectile. The ring has a flared rear part connected with the case and a front part connected with the projectile by attachment means. The front part of the ring is lodged between the rear skirt of the band and the projectile and has a lip co-operating with the first groove or with a second groove in the projectile. A process for mounting the sealing band and ring to link the case and projectile includes sliding the sealing band and ring along the projectile in a single operation.
摘要:
The invention provides a combination of a gun having a barrel and a propellant for launching a projectile from the barrel; and a non-lethal projectile; characterized in that the non-lethal projectile comprises a hollow outer casing formed from a resiliently deformable material, and a plurality of balls within the casing, the outer casing being deformed as it travels along the gun barrel under pressure from the propellant but being sufficiently resilient to resile to a substantially undeformed state upon leaving the gun barrel.

A spin-stabilized projectile adapted to be fired from a weapon barrel, includes a projectile body having a length dimension, a rear length portion, an ogive-shaped front length portion and an intermediate length portion situated between the rear and front length portions; a metal guide band circumferentially mounted on the projectile body; and an undercut provided circumferentially in the intermediate length portion to define an annular chamber with an inner surface of the weapon barrel during travel of the projectile in the weapon barrel upon firing for effecting a pressure equalization of propellant gases flowing past the metal guide band to center the projectile within the weapon barrel.

A switch key tool for setting the pulse repetition frequency code on a laser guided bomb. The switch key tool allows the user to set the pulse repetition frequency code when the laser guided bomb has its switch knobs and also when the laser guided bomb is missing its switch knobs.
摘要:
A method for creating coherent masses of burning matter for countermeasures purposes such as for protecting an aircraft and other vehicles from infrared “heat seeking” hostile missiles and also from high power Laser beams and Laser radar. One or more spurious sources of radiation are created controllably in the general vicinity of the aircraft being protected; in missile countermeasures, each of these spurious sources is capable of emitting infrared energy comparable in wave length and at a higher intensity than that emitted by the target aircraft itself such that the hostile missile will be decoyed away from its intended target by the spurious radiation sources. In this method, the spurious source of radiation is created by igniting a small amount of aircraft fuel that is gelled and controllably ejected from the aircraft. Protection against Laser weapons and radar is provided by interposing the burning mass of matter in the Laser beam so that combusion products in the burning mass serve to degrade beam power. Apparatus for practicing the method is disclosed comprising means for withdrawing a small quantity of fuel from the aircraft fuel tank, means for adding a gelling agent to the quantity of fuel, and means for simultaneously igniting and ejecting the quantity of gelled fuel such that a persistent source of radiant energy that can be used for decoy purposes and attenuating Laser beams is produced.
摘要:
A modular crowd control munition 10 fires a large number of non-lethal soft pellets into a crowd 100 using an explosive charge. The munition 10 contains a pellet matrix 22 that houses the soft pellets 40, and uses a low energy explosive sheet material 50 at the back of the munition 10 to disperse the soft pellets 40. The munition 10 is used for close-in, “last resort”, crowd control to replace the necessity of using deadly force.
