New empirical method to enhance the accuracy in the erosion prediction of cannon tube

Abstract We predict the erosion rate of unknown cannon tubes by substituting measured values of the standard cannon, 155 mm Howitzer M185, and ballistic data for the erosion equation. We know 10 measured erosion values of the standard cannon at every 400 rounds. An approximate formula is derived to interpolate five values up to 2000 rounds. The results of the simulations are analyzed. The new erosion equation is also suggested. This equation produces more accurate cannon tube erosion rate than the Rauf Imam’s empirical approaches. Numerical results are presented.
