AI Technical Summary

Technical Problem

When evaluating the average ballistic differences between the same projectile and different artillery pieces, existing technologies have problems such as high consumption, high risk of false positives, and poor credibility of evaluation conclusions. In addition, it is difficult to effectively evaluate the ballistic performance of non-test support points.

Method used

A new method for evaluating the average trajectory difference of the same projectile but different guns is adopted, which includes the steps of establishing a ballistic simulation model, checking the difference in average trajectory performance, identifying the zero-drag coefficient, calculating the coincidence, determining the distribution characteristics of the parameters of the equivalent dispersion source, determining the distribution characteristics of the parameters of the equivalent same-day error source, estimating the system error, evaluating the average trajectory difference of non-test support points, and evaluating the average trajectory difference of test support points.

Benefits of technology

It realizes the low-consumption, low-false-risk and high-credibility average ballistic difference assessment of test support points, and can provide the average ballistic performance difference assessment information of non-test support points, thus improving the comprehensiveness and reliability of the assessment results.
