| An unguided projectile-accelerator system includes an enclosure, first and second charges, first and second projectiles, and a recoil-absorbing mechanism. The enclosure has an open first end and a closed second end, and the first and second charges are disposed within the enclosure. The first projectile is disposed within the enclosure between the first charge and the first end and is operable to exit the enclosure via the first end and to generate a first recoil in response to detonation of the first charge. The second projectile is disposed within the enclosure between the first charge and the second charge and is operable to exit the enclosure via the first end and to generate a second recoil in response to detonation of the second charge. The recoil-absorbing mechanism is disposed adjacent to the enclosure and is operable to absorb at least a respective portion of each of the first and second recoil. | ||||||

| The present invention relates to a grenade that can be fired from a barrel, for recoilless firing. The barrel is open at both ends and is without any flow cross-section constrictions. The grenade is formed of a grenade base body which surrounds at least one explosive charge, and a flow cross-section reduction device for reducing the flow cross-section of the barrel. The device is arranged in the opposite direction to the firing direction X with respect to the grenade base body. The flow cross-section reduction device is connected to the grenade base body, separated from it, via a connecting device, and is connected to it such that it is stable during firing. A grenade launcher or shell firing apparatus has a grenade such as this, and the grenade firing apparatus has a barrel which is open at both ends and does not have any flow cross-section constrictions. | ||||||
| 144 | Recoilless launching | US12587326 | 2009-09-22 | US07841267B1 | 2010-11-30 | Matthew J. Sanford |
| An arrangement for recoilless launch including a non-gaseous reaction mass having a weight in a range of about 25% to about 75% of a weight of a projectile. For the same projectile energy, less propellant is required than a rocket, which minimizes backblast and reduces before-launch weight. The recoilless launching is adapted to shoulder-launched projectiles in a confined space. The reaction mass may be particles associated with a propellant so as to be released concurrently as the propellant turns into gas and accelerated by and with the propellant gas in a nozzle. | ||||||

| 147 | DEVICES FOR FIRING A PROJECTILE | US12090509 | 2006-10-27 | US20090031912A1 | 2009-02-05 | Robert Jackson Gilbert |
| A housing (1; 100, 104, 102) of a cartridge for a device for firing a projectile has separate first and second chambers (10, 12; 106, 114), each of which contains a respective charge (34, 36; 108, 110, 116, 120) of propellant material. Gas produced by the detonation of one of the charges exits the first chamber to propel the projectile, whilst gas from the detonation of the second charge exist rearwardly from the device so as to counteract recoil. A one way valve may also be provided to help to achieve a high pressure difference between the chambers, where the cartridge has a common igniter assembly. | ||||||
| 148 | Recoilless telescoping barrel gun | US09950493 | 2001-09-11 | US06490959B2 | 2002-12-10 | 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. | ||||||
| 149 | Recoilless and gas-free projectile propulsion | US64717 | 1998-04-23 | US5952601A | 1999-09-14 | Matthew J. Sanford; Larry E. Crabtree; Roger L. Ellis; James F. Cahill |
| A recoilless and gas-free projectile propulsion device is provided. A hol pressure vessel is sealed on a first end to an aft end of a projectile in a launch tube. The pressure vessel is further open on a second end. A propellant charge-filled pressure chamber, defined in a forward portion of the pressure vessel, has holes venting to the pressure vessel aft thereof. A piston, sealed within the pressure vessel for sliding movement therein, is spaced apart from the pressure chamber to define a volume therebetween that receives gases produced during the burning of the propellant charge via the vent holes. A pressure valve divides the volume into a forward section adjacent the pressure chamber and an aft section adjacent the piston. The pressure valve remains closed until a threshold pressure is reached in the forward section at which point the pressure valve opens to join the forward section with the aft section. A countermass is positioned between the piston and the second end of the pressure vessel. When the pressure valve opens, the gases in the volume act on the pressure chamber and the piston. As a result, the projectile with the pressure vessel sealed thereto is propelled forward while the piston moves aft. The piston travels to the second end of the pressure vessel to drive the countermass (e.g., a fluid) out of the pressure vessel at its second end while the gases remain sealed in the pressure vessel which is launched with the projectile. | ||||||
| 150 | Weapons system having a shock absorber | US244267 | 1994-05-20 | US5491917A | 1996-02-20 | Denis Dilhan; Jean Baricos |
| Weapons system comprising a fixed reference, a launcher tube slidingly mounted in relation to the fixed reference and a damper inserted between the fixed reference and the launcher tube. The weapon further comprises a lock serving as a stop for the damper in the launching position, so as to avoid displacement of the damper in the initial launching phase, and a sensor which reacts to projectile launching, capable of releasing the lock so as to rearwardly eject the unit formed by the damper and the launcher tube. | ||||||
| 151 | Composite round/rapid fire gun | US353787 | 1982-03-01 | US4452123A | 1984-06-05 | John W. Holtrop; Bruce C. Bartels |
| A rapid fire gun round is made with a composite chamber. The chamber is led by rotational motion rather than by reciprocating motion. The round will work in a recoilless gun configuration. An alternate arrangement permits multiple barrels to be arranged with an ammunition chain to form a Gatling gun configuration. A liner can be inserted in the gun barrel to be replaced with wear as appropriate. | ||||||

| Rearwardly exhausted powder gases from a recoilless rifle are combined withir and combusted in an afterburner that is attached to the rifle. Thrust produced by the combustion is utilized to assist in counter-recoil. | ||||||
| 153 | System for aiming projectiles at close range | US225801 | 1972-02-14 | US3974740A | 1976-08-17 | Henri Billottet; Patrice Fechner |
| A multiplicity of launching tubes for nonguided projectiles, clustered about a central axis, are divided into several groups of 2n tubes each, the muzzles of each group of tubes being trained in directions diverging from one another in at least one dimension at a small angle designed to spread the projectiles of each group over a predetermined segment of an area centered on the main axis. The tubes of each group are subdivided into pairs whose muzzles are distributed symmetrically about the main axis and which may be fired simultaneously to provide a balanced recoil. A computer determines from the output of a tracking radar the location of a region of uncertainty, centered on the calculated position of a target to be destroyed, and selects the group or groups whose segments cover that region whereupon the tubes of the selected group or groups are fired simultaneously or in rapid succession. The entire array may undergo a sweep motion in one dimension (e.g. azimuth) while the tubes, with axes diverging in the other dimension (elevation), fire repetitively to cover the assigned sector; this sweep motion is superimposed upon the computer-controlled tracking motion designed to keep the main axis of the array in line with the presumed target position as calculated for the moment of impact. | ||||||
| 154 | Highly viscous fluid damper providing regulated non-linear damping for traversing units | US34378073 | 1973-03-22 | US3877552A | 1975-04-15 | HIGGINSON HOWARD P; MACK ROBERT P |
| Fluid dampers having a predetermined non-linear torque/velocity characteristic are provided for azimuth and elevation axes of a traversing unit for a missile launcher. Each fluid damper comprises a pair of coaxially-aligned, truncated cones formed from metals of different temperature coefficients which regulate the spacing between opposing surfaces of the cones and the thickness of a highly viscous fluid (dimethyl polysiloxane) therebetween to maintain a selected non-linear torque/velocity relationship which provides for limiting of the resistance to torque for rapid slewing to a different sector (target acquisition) while maintaining optimal or critical damping required to prevent overshoot and wavering during tracking of a target throughout the flight of a launched missile.
