EFFECT OF ANGLE OF ATTACK, GASS COMPOSITON AND REYNOLDS NUMBER ON FLUTTER BOUNDARY OF BENCHMARK SUPER-CRITICAL WING

Abstract

This paper presents results of the second Aeroelastic Prediction Workshop which uses the Benchmark Super-Critical Wing, BSCW at flutter conditions as a common test case. The primary purpose of this study is to evaluate the effect of angle of attack. To do so, we analyzed BSCW wing at three angles of attack - α = 0deg, α = 1deg and α = 5deg. The second task is to evaluate the effect of gas composition on flutter boundary. The two gases are R-12 heavy gas which was used as a test medium for the wind tunnel test and air.
