Abstract

Performance requirements for existing and future gun systems demand improved lethality at longer ranges. This translates directly into increased muzzle velocity which is achieved by increasing propelling charge energy and, operating pressure. This combination of factors usually results in a decrease in the effective gun barrel life. While improvements in barrel technology to mitigate wear problem are warranted, barrel improvements alone may not be the most cost-effective means; some of the burden for reducing barrel wear problem are warranted, barrel improvements alone may not be the most cost-effective means; some of the burden for reducing barrel wear may be shifted to the ammunition, in the form of wear-reducing additives. The primary objective for the proposed Phase II extended barrel life program is to develop a heating and wear inhibitor for 25mm cased telescoped ammunition. The inhibitor concept is aimed at reducing the severity of the conditions the barrel must withstand. To support this development effort, existing computer sumulation and diagnostic test methodology will be enhanced and incorporated into the development effort. This methodology is expected to benefit subsequent inhibitor development efforts for ammunition and possible commercial applications.
