Abstract : The subject contract was executed on March 20, 1952. Its purpose was basic research and development of ammunition for a proposed short aircraft caliber .60 machine gun. This gun is novel in design. The projectiles and cases are separately loaded, the latter being fired when in a position normal to the bore axis. Hence, the propellant gases must change their direction of flow by 90 deg before entering the bore of the chamber. The scope of the work is set forth in the contract objectives of which there are three: (A) A basic study of the effect on ballistics of free bore, free chamber volume, and gas flow direction at the chamber end. (B) A study of the relative effect on erosion of change in direction of gas flow. (C) The development of a practical, ballistically efficient type of case closure.
