| A projectile deployment system includes an entangling projectile including a pair of pellets and a tether connecting the pellets. A projectile casing includes a pair of sockets, each socket sized to carry one of the pair of pellets and a selectively activatable pressure source, carried by the projectile casing. The pressure source is capable of expelling the entangling projectile from the projectile casing toward a subject. A launcher carries an activator operable to activate the pressure source to expel the entangling projectile from the projectile casing toward the subject. The projectile casing is removably engageable with the launcher to allow removal of the projectile casing from the launcher after expulsion of the entangling projectile from the projectile casing. | ||||||

| Disclosed is a high altitude space launcher system for transferring payloads from surface to orbit at a significantly lower cost than conventional rockets. It comprises a aerostat lifted one stage light gas gun operating in stratosphere that shoots rocket assisted projectiles containing payload at near orbital velocities to a low angle trajectory. Alternatively, to launch acceleration sensitive payloads such as astronauts the light gas gun is replaced with a muzzle loaded conventional gun that shoots a single stage rocket at a much lower velocity. The system is mostly static structure, attached to a tether-elevator that moors it to land or a ship and provided it with electricity and lifts the projectiles to the gun. | ||||||

| A pyrotechnic drive device includes a housing (3) provided with a combustion chamber (5) having pyrotechnic material (15) as well as an activation device (13).

Each pressure-receiving impact of a pressure-receiving element (17, 35) is impacted after the activation of the pyrotechnic material (15) in such a way by the gas pressure generated in this manner that the pressure-receiving element (17, 35) is moved and/or deformed (17, 35) and/or a mechanical impulse is thus transmitted via the pressure-receiving element (17, 35) to an element to be driven (19) so that a connected substance (25) is transmitted. The residual volume of the combustion chamber (5), in which no pyrotechnic material (15) is provided in the initial state, is filled with a liquid, a gel-like or pasty filling material (21), and/or a soft, rubber-like material. | ||||||

| A projectile launching device includes a reactive driver, a flyer housing, a flyer and a compressible buffer member. When detonated, the reactive driver will generate a detonation shock wave. The flyer housing defines a bore. The flyer is disposed in the bore and has a rear surface. The buffer member is interposed between the reactive driver and the flyer. The buffer member has a front surface in direct contact with the rear surface of the flyer. The buffer member is configured and arranged to: receive the detonation shock wave from the reactive driver; modify the detonation shock wave to generate a modified shock wave; and transmit the modified shock wave directly to the flyer to thereby propel the flyer away from the buffer member. | ||||||

| An improved two-stage light gas gun for launching projectiles at high speeds. The gun consists of three tubes: the expansion, pump, and launch tubes. The expansion tube contains a close-fitting expansion piston that is propelled by an explosive charge. The expansion piston in turn drives the pump piston housed within the pump tube by means of a rod connecting the two pistons. The action of the pump piston adiabatically compresses and heats a light gas of hydrogen or helium, bursting a diaphragm at a predetermined pressure and expelling the projectile from the launch tube at a very high speed. | ||||||

| A method for formation of slugs in a gun barrel and acceleration of these slugs up to the speed of 3 km/sec and more is suggested. A selected region of the barrel is filled by water or another liquid, mixture of liquids or slurry. The refrigerating media is supplied into a heat exchanger cooling the selected section of the barrel. The freezing conditions (rate of the heat removal, duration of cooling) assure desired cohesion of the slug and its adhesion to the barrel. When freezing is completed, the axial pressure is exerted on the internal edge of the slug. When the pressure exceeds the adhesion forces, the slug will move toward the open end with acceleration determined by the axial forces. If the exerted pressure force is not sufficient for the slug separation the expansion radial forces are applied to the barrel or the interface between the slug and the barrel is heated. After the separation the compressed media drives the slug toward the open end of the barrel. In the course of the motion the slug accelerates up to the maximal available velocity of the driving fluid. After exiting the barrel the slug impacts a target similarly to a striker or bullet. The impact conditions are determined by the slug velocity, dimensions, shape and structure and are selected to assure a desired material modification (penetration, fracturing, spallation, and plastic deformation). In the course of impact the slug is decomposed, melted and the generated liquid is removed from the impact zone. | ||||||
| 37 | Recoilless telescoping barrel gun | US09950493 | 2001-09-11 | US20020029688A1 | 2002-03-14 | Walter M. Lavin |
| In order to provide a gun in which the recoil force attendant with actuation is reduced, a prototype model of a telescoping barrel gun has been designed. In this design, an inner barrel, which contains and directs the projectile, is made to slide forward within an outer barrel when the gun is actuated. The motion of the inner barrel is then stopped while the projectile moves unimpeded. The telescoping barrel design functions together with a design which requires a portion of the cartridge's propellant energy be used to produce a reduction in the force of the gun's recoil when fired. Upon firing, some of the propellant gases are channeled forward in the gun to an air space, which lies between the two concentric barrels. The forward motion of the inner barrel forces the gases in this air space from the gun through small holes located in the distal area of the outer barrel. The discharge of these gases is rearwardly directed in order to counteract the gun's recoil. After firing, the gun must be manually reloaded and the member's reassembled to their pre-actuation positions before firing again. | ||||||
| 38 | Porous nozzle projectile barrel | US137544 | 1998-08-20 | US6089139A | 2000-07-18 | Ronnie David Russell |
| A porous barrel, projectile passageway, or tube as a type of supersonic nozzle for projectile propulsion therein and method for optimizing projectile velocity therethrough. The porous barrel features a barrel wall containing holes, passageways, or otherwise porous material through the barrel wall that allows gas, fluid, or other matter to exit or move in a direction away from the barrel interior. The flow of gas, fluid, or other matter away from the barrel interior allows gas within the barrel to expand in a direction transverse to the projectile path. The amount of transverse expansion of the gas in the barrel interior can be controlled by the porosity of the barrel wall to cause any desired amount of gas expansion. Transverse expansion allows axial gas velocities within the barrel to exceed the local speed of sound as if the gas had passed through a converging diverging nozzle. In one embodiment, a pressurized gas source supplies a pressure propelling the projectile, and gas outflow from passageways through the barrel wall allows gas within the barrel to obtain supersonic velocities as the projectile accelerates. | ||||||
