Title: Innovations by David P Perrin
Introduction
David P Perrin is an accomplished inventor based in Charlotte, VT (US). He has made significant contributions to the field of gun barrel technology, holding a total of 3 patents. His work focuses on enhancing the performance and durability of gun barrels under high-temperature conditions.
Latest Patents
One of his latest patents is for a multi-layer composite gun barrel. This innovative design features an integral metal alloy jacket portion that forms the exterior cylinder of the barrel. Inside, there is a forebarrel interior liner cylinder that is substantially bonded within the jacket portion, along with an unbonded breech portion liner made from a high melting temperature refractory metal alloy. This design is specifically engineered to resist erosion caused by hot gun gases in the barrel breech area.
Another notable patent is for a gun barrel designed for use at high temperatures. This invention allows the gun to operate effectively at relatively higher temperatures. The barrel consists of at least two layers, with the inner layer made of a refractory material, which can be either a metal or non-metal refractory. The liner is bonded to an outer jacket material formed from an alloy of nickel, aluminum, and molybdenum. This construction ensures that the gun does not expand excessively when heated, as the coefficient of expansion of both the liner and jacket is relatively low. The jacket metal also exhibits higher strength at elevated temperatures compared to conventional gun barrel steel.
