ABSTRACT:
My Ring Airfoil Glider Expendable Cartridge and Glider Launching Method is form launching a reduced caliber ring airfoil glider from a conventional grenade launcher barrel with preferred application for less lethal use. A caseless ammunition base contains a primer communicating with a propellant in a rupture disk sealed chamber with a vent used to create, seal and channel propelling gas into a space behind a sabot mounted on a central guide on the base, whereupon releasing the gas, the sabot aligns, seals, pushes and rotates the glider in passage down the barrel, to a point of maximum velocity, whereon, the propelling gas is vented ahead of the glider by the central passage in the sabot as it leaves the guide, whereupon, the bore decelerates the sabot by friction freeing the glider to fly down the bore centered by a turbulent boundary layer of air until it exits the muzzle.
