Firing Accuracy in Rotor Dynamics Prediction of Unbalanced Mass and Bearing Clearance

Abstract

The XYZ center of gravity of the barrel part of the M134 Gatling gun and the components composed of bullets was calculated from the five types of clearances between the bearings without clearance to the bearings with clearance. According to the calculation of five clearances, the angle deviation is about 11.5⁰, and based on the target of 3000m, the sideflight is about 600 meters. From the perspective of Gatling weapons, it has been officially determined that transfer weapons must primarily rely on surface killing.
