    Abstract

    Wind Tunnel Tests Were Carried Out To Determine The Aerodynamic Characteristics Of A 1/10th Scale Payload Plus Lind Stage Configuration Of AGNI Missile Model. The Tests Were Conducted In The NAL 1 .2M Transonic Wind Tunnel At Nominal Mach Number Of 2 .5, 3 .0, 3.5 And 4.0 Through An Angle Of Attack Range Of -5 ° To 15° And At 0° And 22.5 ° Model Orientations . The Reynolds Number (Based On Model Diameter) Varied From 2.24 Millions To 3 .67 Millions As The Mach Number Varied . Some Tests Were Repeated After Removing, The Ullage Motors To Study The Effects On Longitudinal Characteristics. The Results Are Presented In The Form Of Tables And Plots. The Limited Analysis Of The Test Results Indicate That For The Test Mach Number Range, The Normal Force And Pitching Moment Display Linear Behavior As Expected.The Orientation Of Protrusions And The Removal Of Ullage Motors Reduces The Lift Curve Slope, To An Appreciable Amount. The Error Estimated In The Measurements Are Of Lower Magnitude
