National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Understanding and Predicting Gun Barrel Erosion.

ADA440938

Publication Date	2005
Personal Author	Johnston, I. A.
Page Count	51
Abstract	The Australian Defence Force will soon have to contend with gun barrel erosion issues arising from the use of new low-vulnerability gun propellants, the acquisition of new ammunition and gun systems, and possible modifications to existing propelling charge designs. A critical, technical review of advances is gun barrel erosion research, mitigation, and assessment over the last fifteen years is presented. Known and postulated erosion mechanisms, obtained through recent experimental and numerical modelling work, are described and contrasted. New approaches to erosion mitigation and updated knowledge of existing methods are reviewed. Also included is an assessment of the utility of the various erosion modelling and experimental techniques, and notes on their possible use of defence applications in Australia.
