Abstract
A cartridge (10) for accelerating a projectile (18) includes a light gas (34) pressurized in a sealed container (12) to 5,000 - 10,000 psi. Upon ignition in the sealed container (12), a gas (34) mixture having a low or intermediate molecular weight and a high or low energy density is applied as a high sound speed gas to accelerate the projectile (12) to speeds of above about 2.4 km/sec.
Claims
AMENDED CLAIMS
[received by the International Bureau on 16 August 1996(16.08.96); original claims 1, 3, 15, 17 and 19 amended; original claim 41 cancelled; remaining claims unchanged (4 pages)]
1. A cartridge comprising a housing carrying a projectile, the housing including: a sealed container means including: a mixture comprising an oxidizer gas and helium gas at a pressure of at least several hundred atmospheres, a fuel having molecules including hydrogen atoms, a solid propellant, a front wall means confining constituents in the sealed container means from the projectile; the propellant, fuel, oxidizer gas, helium gas, sealed container means and front wall means being positioned, arranged and having constituents so that in response to ignition within the sealed container, the propellant, fuel, helium gas and oxygen are combusted and mixed to increase the pressure on the front wall means to a sufficiently high value to burst the front wall means so a gas mixture including the fuel, helium gas and oxygen having a pressure substantially higher than the pressure of the mixture in the sealed container means is applied to the projectile to accelerate the projectile in a barrel in which the projectile is located.
2. The cartridge of claim 1 wherein the sealed container means includes the propellant and piston means positioned between the propellant and gas in a forward portion of the sealed container means, the propellant when ignited generating combusting gas behind the piston means to drive the piston means forward and to increase the pressure on the combusting gas in the forward portion of the sealed container means and cause high pressure gas initially in the sealed container means to be supplied to the projectile considerably prior to gas resulting from combustion of the solid propellant.
3. The cartridge of claim 2 wherein the gas in the mixture in the sealed container means has a relatively low energy density below about 7 kilojoules per gram.
4. The cartridge of claim 3 wherein the sealed container means includes a single sealed container, and the piston means comprises a single piston having openings so the same mixture is resident on both sides of the piston.
5. The cartridge of claim 2 wherein the piston means includes openings so the gas is resident on both sides thereof.
6. The cartridge of claim 5 wherein the solid propellant comprises multiple rods surrounded by the gas in the sealed container.
7. The cartridge of claim 6 wherein the rods are elongated in a direction of gas flow through the ruptured diaphragm means.
8. The cartridge of claim 1 wherein the sealed container means includes plural nested sealed containers, some including helium and an oxidizer gas at pressures of at least several hundred atmospheres and others including fuel at pressures approximately equal to the pressure in said some containers, the nested sealed containers and the propellant being positioned and arranged so ends of the sealed containers proximate the projectile and included in the front wall means are ruptured and gas from the plural containers is mixed and ignited behind the projectile in response to increased gas pressure produced in the plural sealed containers in response to ignition of the propellant.
pressure on the gas in the forward portion of the particular sealed container.
15. A cartridge comprising a housing carrying a projectile, the housing including: a sealed container means including a first combustible gas at a pressure of at least several hundred atmospheres, a fluid reactant sealed to a pressure of at least several atmospheres, the gas including at least 50% by mole fraction of hydrogen or helium, a solid propellant, diaphragm means confining the gas in the sealed container means from the projectile, the propellant, gas, reactant, sealed container means and diaphragm means being positioned, arranged and having constituents so that in response to ignition of constituents in the container the first gas and the reactant are mixed and combusted to increase the pressure on the diaphragm means to a sufficiently high value to burst the diaphragm means so there is formed a gas mixture including the gas and reactant in gaseous form, the gas mixture having a pressure substantially higher than the pressure of the mixture in the sealed container means and being applied to the projectile to accelerate the projectile in a barrel in which the projectile is located.
16. The cartridge of claim 15 wherein the gas and reactant are respectively first and second gases, the second gas having a pressure of at least several hundred atmospheres .
17. The cartridge of claim 16 wherein the first and second gases are sealed in the same container and together form a gas mixture having a relatively low energy density in the range below about 7 kilojoules/gram
29 and a relatively low molecular weight no higher than about 12.
18. The cartridge of claim 15 wherein the gases are at ambient temperature .
19. The cartridge of claim 17 wherein the gas mixture consists essentially of njHe + n202 + Q, where n, is smaller than nl and Q is a fuel in an amount sufficient to at least consume all the oxygen.
20. The cartridge of claim 19 wherein Q is selected from the group consisting of H2 and CH4.
21. The cartridge of claim 17 wherein the container includes a piston positioned behind a forward portion of the container, gas behind the piston when ignited driving the piston forward to increase the pressure on gas in the forward portion of the sealed container.
22. The cartridge of claim 21 wherein the solid propellant is located in the container behind the piston.
23. The cartridge of claim 22 wherein the piston includes openings so the same gas is resident in the sealed container on both sides of the piston.
24. The cartridge of claim 23 wherein the propellant is elongated in the direction of gas flow through the diaphragm.
25. The cartridge of claim 16 wherein the first and second gases are sealed in different containers.
26. The cartridge of claim 25 wherein the first gas consists essentially of an oxidizer and helium.
