Title: Innovations by Raymond Langlois
Introduction
Raymond Langlois is a notable inventor based in Loretteville, Canada. He has made significant contributions to the field of lightweight firearms, holding a total of four patents. His innovative designs focus on enhancing the performance and durability of recoilless guns.
Latest Patents
Langlois's latest patents include the "Filament-wound venturi" and the "Carbon fibre gun barrel." The filament-wound venturi is designed for lightweight firearms, utilizing a resin-impregnated multi-filament fiber material. This construction allows the venturi section to withstand high transient pressures and temperatures during firing. The manufacturing process involves winding the material on a mandrel, curing it, and then machining it for assembly. This design results in lighter and more cost-effective recoilless guns that can fire more rounds before experiencing excessive erosion.
The carbon fibre gun barrel is another innovative creation by Langlois. It is formed from an epoxy-resin impregnated carbon fibre material, which is also wound on a mandrel and cured. This barrel can endure extremely high internal pressures and temperatures, allowing it to fire upwards of 30 rounds before failure, compared to only 5 to 10 rounds for conventional guns. This advancement significantly improves the longevity and reliability of lightweight recoilless firearms.
