The Flow Field About the Muzzle of an M-16 Rifle
Abstract
An experimental technique is developed which permits the obtaining of detailed time-displacement histories of observable discontinuities in the muzzle gas flow fields that form about weapons during firing. The technique is applied to the flow from the muzzle of an M-16 rifle firing standard ball ammunition. Data is presented both as full discontinuity contours and as discontinuity trajectories along the axis of symmetry. The former indicate the details of muzzle jet-free air blast coupling; while the latter demonstrate the applicability of analytical techniques to the flow field. Additionally, a data reduction scheme is proposed which permits the inference of property values in the flow based on a combination of empirical and analytical techniques.
