Zusammenfassung:Tube wear is a major mode of failure in guns. Wear produces a degradation in ballistic performance, i.e., a decrease in muzzle velocity. The general goal of this study was to investigate gun tube wear using data available from periodic firings of reference calibration rounds in propellant acceptance tests. It is demonstrated herein that it is possilbe to estimate wear in a given tube using the mean and/or standard deviation of muzzle velocity from reference lot samples of size n=7 or 10 rounds for the 155 MM and 105 MM guns respectively. Because ballistic tests can be used effectively for estimation of tube wear, a sound basis for life estimation of gun tubes can be developed. (Author)
