Abstract : The M16 rifle system provides an appropriate basis for a discussion of the malfunction modeling procedure. A brief description of the rifle mechanism functioning process together with the governing equations is presented. The system characteristic signature curve is introduced and its relevance to malfunctions explained. The signature curve is unique for each system and relates the cyclic rate of the rifle in terms of ammunition ballistics. Malfunction criteria superimposed on this curve establishes the probability of system malfunctioning. The key element in this procedure is embodied in equipment designed to measure certain system parameters nondestructively. These parameters provide feeder material for the mathematical model developed to produce the characteristic curve. Conclusion of the subject is in the form of use and potential to rifle and ammunition producers. (Author)
