Abstract
Pitch Damping Derivatives Were Measured On A 1/12 .5 Scale Prithvi Model Using The Forced Oscillation Technique In The NAL 1 .2m Tunnel. The Tests Were Made In The Mach Number Range Of 1 .5 To 3 .0 And At Angles Of Attack 0, 3 And 6 Deg . The Tests Were Conducted For Two Axes Of Oscillation Located At 3 .8 And 4 .05 Times The Body Diameter From The Nose. While A Majority Of The Tests Were Conducted On The 'Plus' Configuration, A Few Tests Were Also Conducted On The Into Configuration To Study The Effect Of Roll Orientation Of The Model . Both Configurations Exhibited Positive Damping Over The Range Of Test Parameters. Effects Of Angle Of Attack And Model Roll Orientation Were Found To Be Small .
