61	Hybrid electrothermal light gas gun and method	US149354	1993-11-09	US5429030A	1995-07-04	Derek A. Tidman
A pressurized light gas in a first chamber segment of a light gas gun is heated and highly pressurized by an electric discharge. Solid chemical propellant in a second chamber segment behind and separated from the first chamber segment by a perforated wall is ignited by the heated and highly pressurized light gas to form a gaseous piston to assist in accelerating the light gas against a projectile.

65	Ram accelerator	US662913	1991-03-01	US5121670A	1992-06-16	Edward B. Fisher
The invention comprises a method for ram accelerating a projectile which comprises charging a tube, having an inlet end for accepting the projectile and a muzzle end from which the projectile may leave the tube, with a combustible gas mixture at an initial elevated pressure in the absence of combustion, so that the projectile may be accelerated by combustion of the mixture behind the projectile as it passes through the tube from the inlet end to the muzzle end; introducing the projectile into the inlet end; igniting the combustible gas mixture between the projectile and the inlet end; and creating the elevated pressure within the tube by means of a shock wave within the combustible gas mixture to obtain the elevated pressure before the projectile passes through the gas. Desirably, a static elevated gas pressure is created at least just prior to passage of the projectile through the gas.The invention further includes a ram accelerator for practicing the method of the invention.
66	Remotely actuated tow line throwing device	US933808	1986-11-24	US4784035A	1988-11-15	Stanley S. Fishfader; Sanford Friezner; Keith L. Kirkeide; Stanley G. Putzke; Stanley J. Singer
A throwing device including, a throwing gun formed by a high pressure chamber located within a low pressure chamber. A first frangible diaphragm having a predetermined breaking pressure interconnecting the two chambers. A second frangible diaphragm closing off the lower pressure chamber and having a predetermined breaking pressure lower than the breaking pressure of the first diaphragm. A barrel mounted adjacent to and extending from the second frangible diaphragm. A projectile located within the barrel. A main charge substantially located within the high pressure chamber and an ignition charge coupled to the main charge for igniting the main charge upon activation of the ignition charge. The ignition of the main charge providing for the production of rapid burning forming gas having an increasing pressure within the high pressure chamber. When the pressure reaches the predetermined breaking pressure for the first flangible diaphragm, the first diaphragm bursts to allow the high pressure gas to escape by rapidly expanding into the low pressure chamber. When the pressure in the low pressure chamber raeches the predetermined breaking pressure for the second flangible diaphragm, the second diaphragm bursts to allow the low pressure gas to escape into the barrel to propel the projectile located within the barrel.

A method for accelerating projectiles comprises introducing the projectile into an accelerator barrel, feeding a combustible gas mixture into said barrel and igniting said mixture to accelerate the projectile, and is characterized in that a fluid is stored in the projectile and is ejected therefrom into the space between the projectile and the barrel. Suitable accelerator systems are disclosed.
74	A system for reducing the effects of powder temperature sensitivity on firing with guns	EP92850219.4	1992-09-14	EP0538219A1	1993-04-21	Franzén, Arne; Larsson, Larseric; Nilsson, Neile; Fredriksson, Lars-Berno
A system for compensating the dependence of the muzzle velocity and barrel pressure on the temperature of the powder on firing of primarily high velocity ammunition from guns is proposed. The firing is effectuable by means of charges (1, 2, 3, 4, n) which form combinations of part charges of different or identical charge types/powder varieties and/or charge sizes. Each respective part charge in each combination makes its contribution to the muzzle velocity effectuated by the combination. In the establishment of each respective combination for realizing a desired muzzle velocity, allowance is made for a powder temperature prevailing in the part charges on each firing occasion. The purpose of this consideration is to prevent the action of the powder temperature entailing that the muzzle velocity assumes an unacceptable level. In addition, the muzzle velocity can be checked and controlled with great accuracy.
