Abstract
A cartridge case and nozzle assembly is made from a single element of a lightweight durable polymer resin. The cartridge case and nozzle insert into a launch tube of an anti-armor projectile launcher and have improved adhesive connection to reduce relative movement between the assembly and the launch tube. Improved tolerances and better matching of the assembly and the launch tube provide improved reliability for firing. The adhesive connection prevents the launch tube from being reused by adversaries.
Claims12
An integral cartridge case and nozzle device attaching to an interior surface of a launch tube of a portable launcher and receiving a projectile, comprising a cylindrical cartridge case portion proximate a venturi portion flaring out from the cartridge case portion, wherein an exterior surface of the cartridge case portion has a diameter slightly smaller than a diameter of the launch tube interior surface, and wherein the exterior surface of the cartridge case and nozzle device includes an adhesive for adhesively attaching to the interior surface of the launch tube, wherein adhesive is applied to virtually the entire exterior surface of the cylindrical cartridge case portion.
A recoilless projectile launcher device having a launch tube, a cartridge case and nozzle, the cartridge case and nozzle inserting into a first end of the launch tube, wherein the cartridge case and nozzle are integrally molded and wherein the launch tube has an interior surface with a portion proximate the first end tapering from the first end, and wherein the cartridge case has an exterior surface tapering from the nozzle portion so that the taper of the exterior of the cartridge case complements the taper of the interior of the launch tube whereby the exterior surface of the cartridge case is non-extractably secured with adhesive to the interior surface of the launch tube.
An integral cartridge case and nozzle device adapted for attaching the interior of a launch tube of a portable launcher and receiving a projectile, comprising a cylindrical cartridge case portion proximate a venturi portion flaring out from the cylindrical cartridge case portion, wherein adhesive is applied to virtually the entire exterior surface of the cylindrical cartridge case portion.
