Abstract:

A 9-month program was conducted to develop improved 30mm GAU-8 rifling and deliver test barrels to the Air Force which incorporated the new rifling designs. Gain twist rifling was designed. Two rifling groove configurations, modified conventional and sawtooth, were designed based on thermal analysis, rotating band engraving considerations and FINE code analysis. Two 30mm GAU-8 barrels with modified conventional gain twist rifling and two barrels with sawtooth gain twist rifling were fabricated and delivered to the Air Force.
