A Quick Approach to Correct Range Prediction of A Surface to Surface Rocket Fitted with a Nonstandard Fuze

Abstract

Equipping a nonstandard fuze to an unguided artillery rocket could affect the rocket characteristics and hence different flight trajectory. Consequently, the firing tables provided by the rocket manufacturer are no longer accurate. This paper investigates a quick and low cost approach that can mitigate this problem. The approach was applied to a case study of a 122 mm artillery rockets fitted with a fuze whose shape and mass are different from the original design. Available data from live fire tests were utilized to evaluate the accuracy of the prediction. The results suggested that the error was higher at greater quadrant elevation and the error of one sample point near the maximum range was up to 7.8%.
