Patent ID: 7624668

Claim:
An arrangement for recoilless launching, comprising: a portion being launched, wherein said portion includes a predetermined weight; a non-gaseous reaction mass including a weight in a range of about one-fourth to about three-fourths of said predetermined weight; a pressure vessel moveably receiving the non-gaseous reaction mass; and a propellant for generating pressurized propellant gas in the pressure vessel so that said portion and said non-gaseous reaction mass are motivated in opposite directions by said pressurized propellant gas, wherein a composition is comprised of said non-gaseous reaction mass and said propellant, wherein said non-gaseous reaction mass is comprised of an inert material as a particulate material, wherein the inert material is distributed, uniformly, in the composition, and wherein the propellant progressively reacts to generate said pressurized propellant gas while the inert material is concurrently released from the composition at a rate corresponding to a generation rate of the pressurized propellant gas.
