Abstract : A study was made to determine if solid state devices could be used to improve the functional characteristics and reliability of Trainfire Target Holding Mechanisms, M31A1. Two experimental control circuits were designed and built. In each circuit a silicon controlled rectifier, designated SCR, replaced the conventional relay which is used in the standard control circuit. The experimental control circuit assemblies were individually installed in a standard M31A1 mechanism and tested under firing conditions with M1D, M14 and M16 rifles. The target kill reliability with each weapon was better than 99 percent. It is concluded that solid state devices provide improved functional characteristics and reliability without sacrifice in simplicity and cost. (Author)
