121 In-line annular piston fixed bolt regenerative variable charge liquid propellant gun with variable hydraulic control of piston EP85103915 1985-04-01 EP0161448A3 1987-02-04 Magoon, Inder Kumar

A regenerative liquid propellant gun structure in which the differential area piston is annular, has an open peripheral cylindrical skirt extending away from the combustion chamber to define a propellant reservoir, and has an aperture in the piston head permitting overrunning of a fixed bolt. The fixed bolt is cylindrical with an enlarged band to fit the aperture to block flow of propellant until firing and to define with the edge of the aperture a variable annual orifice for propellant injection as the piston moves. There is a second free piston overrunning the bolt having a forward portion mating with both the inside of the differential area piston and the exterior of the cylindrical skirt so that the skirt constitutes a piston in a circular dashpot in the second piston. The second piston also contains a fluid accumulator, fluid conduit means interconnecting the accumulator and the dashpot and means for changing the cross sectional area of the fluid conduit means to provide a variable hydraulic resistance to the differential area piston during firing.

127 Light gas gun US14205064 2014-03-11 US09915496B2 2018-03-13 David Wayne Bergeron
An improved light gas gun launches a projectile in a light gas atmosphere as it travels through a frictionless barrel to achieve high muzzle velocities, decreased acoustic signatures, and increased ranges. The light gas atmosphere is introduced by a purge valve prior to firing or by a muzzle valve that holds a positive light gas pressure on the barrel and breech. The muzzle valve also routes the majority of propellant gases through a suppression canister, reducing the light gas gun's acoustic signature. The frictionless barrel uses light gas propellant routed through gas bearings to keep the projectile centered in the barrel and preclude the projectile from contacting the barrel walls, eliminating barrel wear.

129 Mechanisms for firing projectiles and methods of their use US14399744 2013-03-18 US09459059B2 2016-10-04 Peter John Hamilton
A method of firing projectiles without the use of cartridge cases by electronically controlling the dynamics of internal ballistics created by combustion of Nitrous Oxide and a fuel injected under high pressure at oxygen rich or stoichiometric ratios. The shape of injector nozzles and the combustion chamber as well as a timed sequence of Nitrous Oxide injection, fuel injection and their ignition are used to create correct ballistics. The timing of the injection and ignition sequence is automatically altered dynamically by an electronic control unit that obtains information from sensors and from an operator to tune the combustion for each firing so that the internal ballistic pressure versus time curve is favorable.
130 System and Method for Accelerating a Mass Using a Pressure Produced by a Detonation US15003525 2016-01-21 US20160216387A1 2016-07-28 Larry W. Fullerton; James L. Teel; Herman M. Thompson, JR.
The present invention pertains to a system and method for accelerating a mass using a pressure produced by a detonation, where the mass is accelerated over a movement range using a detonation of a pressure wave generator that produces a pressure within a coupling component that is applied to a piston having a surface area that produces a resultant force, where the acceleration of the mass determines the resulting force. The resulting force may be directed vertically and perpendicular to a target media to conduct an acoustic wave into the target media. The system may be configured to direct the resulting force horizontally and parallel to a target media to conduct a plane shear wave into the target media. Two systems may be configured to direct two resulting forces horizontally and parallel to a target media to conduct a spherical shear wave into a target media, where the two resulting forces are directed in opposite directions and separated by some distance.

Various configurations and geometries of the propellant, electrodes, and apparatus are possible. In one example, the electrodes are supplied a direct current, which causes combustion of the propellant at the positive electrode. In another example, the electrodes are supplied an alternating current, which initiates combustion of the propellant at both electrodes.
138 Multivalve hypervelocity launcher (MHL) US11327479 2006-01-09 US07775148B1 2010-08-17 Patrick P. McDermott
Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable. The valves close automatically after the projectile has exited the barrel, allowing a new projectile to be introduced into the breech and the AGC to be recharged with high-pressure gas.
139 Ignition systems for hybrid and solid rocket motors US10269366 2002-10-11 US06912839B2 2005-07-05 Korey R. Kline; Derek Dee Deville
An ignition system for a rocket motor includes a soft plastic tube that extends up into the combustion chamber and is coupled to an oxidizer source. Ignition source wires extend through the tube and terminate at a first end at a location which is set back from the end of the tube, and have a second end coupled to an electric power supply. In operation, an oxidizer is introduced into the tube simultaneously with activation of the power supply. The set back portion of the plastic tube becomes fuel for the oxidizer and is consumed, introducing a fire plume into the combustion chamber. The tube introduces additional fuel distinct from the fuel grain or propellant which is in contact with the both the ignition source wires and oxidizer. In addition, the tube will not damage the nozzle as it is being blown of the rocket during the main propulsion phase.
