The Aerodynamic Properties of the 155-mm Shell M101 from Free flight Range Tests of Full Scale and 1/12 Scale Models
Abstract
The aerodynamic properties of the 155-mm HE Shell M101 as determined from Free Flight range firings of the full scale projectile and accurately scaled models 12.7 mm in diameter and semiscaled models of the same size are presented. It was found that at supersonic velocities, the aerodynamic characteristics are similar for the model and the full scale projectile. However, at lower transonic and subsonic velocities, the full scale data and the semiscaled model data differ. The accurately scaled model data may also be somewhat different from the full scale data, but the differences are considerably smaller than the differences shown by the semiscaled model data.
