Abstract:

This invention relates to methods of generating gases and more particularly to methods of generating hydrogen gas. Acceleration of projectiles launched from gun, rocket, and missile systems is limited by the sonic velocity of gas products from propellants. Conventional gun propellants nitrocellulose generate heavy gases like carbon dioxide, carbon monoxide, nitrogen oxide, and water vapor whose sonic velocity seldom exceeds 500 msec at ambient temperature. The maximum speed to projectiles launched from gun barrel by such gases barely reaches 1 kmsec. Keywords Patent applications.
