Abstract:

A basic design for the MX-82 primer, with design changes which proved to be necessary to meet functional requirements was developed and the specified primer requirements were met. In addition 2 alternative primer designs were prepared. A first alternate design featuring drawn parts in place of screw machine parts which can be manufactured at substantially lower cost was developed to a point where satisfactory performance is indicated by static tests in the firing lock. A second alternate which provides vast simplification and greater reduction in cost utilized an external gas sealing percussion element and a single drawn case with a folded closure. This primer showed metal parts failure on the first shot in a 175 mm weapon indicating the need for stronger construction to withstand the long pressure duration in an artillery weapon.
