Shadowgraphs from Range – Count Rotations• The rotation of the round as it traverses the range can be tracked via a spin pin• The rotation rate leads to a measurement of roll torque developed by pinsPin Used to CountRevolutionsStations 22 and 276.7m to 8.2mLittle Spin ObservedAuthorized for public release. Distribution Unlimited.Stations 295 and 30090m to 91.4mOver 90° rotation06/21/2007 22
Range Test Comparison with CFD• Comparison with measured data not as good as expectedDrag under predicted at all Mach numbersRoll torque prediction worse as Mach number increasedAuthorized for public release. Distribution Unlimited.06/21/2007 23
