    Abstract

    Six Component Measurements Were Carried Out On A Slender Boo I Model With Lifting Surfaces (Kaha Model) To' Study The Vortex Flows Of Such Configurations At High Reynolds Numbers Upto Very High Incidences. The Basic Bod F Consists Of A 105 Mm (3D) Long Tangent Ogive Nose And A 420 Mm (12D) Long Circular' Cylinder After body With A Diameter Of 35mm (D) . To This Slender Body Cruciform Lifting Surfaces Of 105mm (3D) And 140mm (4D), Span, And A Constant Chord Length Of 35mm Were Added To Realize Body+Wing, Body+Tail And Body+Wing+Tail Combination : The Experiments Have Been Carried Out In The , O .6m X 0 .6m Pressurized Low Spec' Wind Tunnel Of The DEVILRY In Gottingen . The Test Reynolds Number, Based' On Bad Diameter And A Test Section Speed Of 31 M/Sec, Varied From 0 .7 Million;:; To 5 . Million . The Angle Of Attack Was Varied From -2° To 70° In Two Ranges',.Using . ; A ; Straight Sting For Incidences Up to 30° And A 40° Cranked Sting At Higher' Incidences . With Respect To The Pitch Plane The Cruciform Lifting Surfaces Were : Arranged In N+"" And "X" Position . In This Report The Complete Test Result,1 , In Form Of Tables And Plots With A • Limited Analysis . At High Incidence : And At Higher Reynolds Numbers The Model' Entered Into Severe Vibrations. 'Thus Data Could Not Be Obtained For Most Of The Configurations< Around An Angle O Attack Of 50°.
