Claims
- 1. A bulk loaded liquid propellant gun utilizing a liquid propellant for firing a projectile from a barrel comprising:
- an elongated barrel;
- a bolt within said barrel movable between loading and firing positions to load said barrel and to seal the rear thereof;
- a projectile within said barrel forward of said bolt;
- a depression on the rear of said projectile to provide a void between said bolt and said projectile;
- a gas filling said void;
- an injection port in said barrel communicating to said void while said bolt is in loading position and sealed by said bolt while in firing position;
- ignition means in said barrel between said bolt and said projectile while said bolt is in firing position to ignite said liquid propellant; and
- compression means to place said liquid propellant and said gas at a pressure greater than atmospheric pressure.
- 2. A bulk loaded liquid propellant gun as described in claim 1 wherein said gas is air.
- 3. A bulk loaded liquid propellant gun as described in claim 1 wherein said gas comprises gaseous products of combustion of said liquid propellant.
- 4. A bulk loaded liquid propellant gun as described in claim 1 wherein said gas comprises propellant vapors.
- 5. A bulk loaded liquid propellant gun utilizing a liquid propellant for firing a projectile from a barrel comprising:
- an elongated barrel;
- a bolt within said barrel movable between loading and firing positions to load said barrel and to seal the rear thereof;
- a projectile within said barrel forward of said bolt;
- a projection on said bolt to provide a void between said bolt and said projectile;
- a gas filling said void;
- an injection port in said barrel communicating to said void while said bolt is in loading position and sealed by said bolt while in firing position;
- ignition means in said barrel between said bolt and said projectile while said bolt is in firing position to ignite said liquid propellant; and
- compression means to place said liquid propellant and said gas at greater than atmospheric pressure.
- 6. A bulk loaded liquid propellant gun as described in claim 5 wherein said gas is air.
- 7. A bulk loaded liquid propellant gun as described in claim 5 wherein said gas comprises gaseous products of combustion of said liquid propellant.
- 8. A bulk loaded liquid propellant gun as described in claim 5 wherein said gas comprises propellant vapors.
- 9. A bulk loaded liquid propellant gun utilizing a liquid propellant for firing a projectile from a barrel comprising:
- an elongated barrel;
- a bolt within said barrel movable between loading and firing positions to load said barrel and to seal the rear thereof;
- a projectile within said barrel forward of said bolt;
- a projection on the rear of said projectile to provide a void between said bolt and said projectile;
- a gas filling said void;
- an injection port in said barrel communicating to said void while said bolt is in loading position and sealed by said bolt while in firing position;
- ignition means in said barrel between said bolt and said projectile while said bolt is in firing position to ignite said liquid propellant and
- compression means to place said liquid propellant and said gas at a pressure greater than atmospheric pressure.
- 10. A bulk loaded liquid propellant gun as described in claim 9 wherein said gas is air.
- 11. A bulk loaded liquid propellant gun as described in claim 9 wherein said gas comprises gaseous products of combustion of said liquid propellant.
- 12. A bulk loaded liquid propellant gun as described in claim 9 wherein said gas comprises propellant vapors.
