A Mathematical Model of the 30 MM Advanced Medium Caliber Weapon System (AMCAWS-30)

Abstract

A mathematical model for the AMCAWS-30MM weapon is developed using the generalized d'Alembert force equations. The development of the one degree of freedom differential equation of motion for the weapon is shown. The equation accounts for operations including feed, eject, chamber locking, round crush-up, chamber translation, face cam rotation, and drum cam rotation. The resultant equation is numerically integrated to obtain the time response of position, velocity, acceleration, and force for the major components. The solution is based on the known drive motor characteristics. The numerical integration is done using the HPCG subroutine out of the IBM SSP Math Library. The total program is modularized and inclusions of additional parts or design changes in the weapon can be incorporated without extensive revision of the program. The program is written in FORTRAN.
