Abstract
The present invention relates to a laser ignition system for a large-caliber artillery, which provides a linear laser beam shape, and the ignition system of the present invention evenly combusts a cylindrical large-caliber artillery propellant with a hollow center in an energy-efficient manner using a laser in longitudinal and radial directions.
Claims19
A laser ignition system for a large-caliber artillery propellant, comprising:
- a breech block coupled to a gun barrel to seal combustion gas generated by combustion;
- a laser transfer part mounted in front of an inclined through hole of the breech block to transfer a laser from a laser generator to the large-caliber artillery propellant;
- a laser diffusion part mounted behind the through hole of the breech block;
- and
- the large-caliber artillery propellant mounted inside the gun barrel and formed with a center through hole for firing a shell.

A laser ignition system for a large-caliber artillery propellant, comprising:
- a laser generator configured to generate a laser;
- a gun barrel in which combustion gas is generated by combustion;
- a breech block having a rear inner diameter portion into which a front of the gun barrel is inserted, thereby preventing leakage of the combustion gas to an installation gap of the gun barrel;
- a laser diffusion part mounted behind a through hole of the breech block;
- a laser shape conversion part positioned at a front of the laser diffusion part and converting a circular shape of the laser into a linear shape using a Powell lens;
- a laser transmission part positioned at a rear of the laser diffusion part and sealing propellant combustion gas generated in the gun barrel while transmitting the converted laser received from the laser shape conversion part;
- and
- a large-caliber artillery propellant mounted inside the gun barrel, formed with a center through hole, and causing local combustion using the converted laser passing through the laser diffusion part.
