High Reynolds Number Tests of the CAST 10-2/DOA2 Transonic Airfoil at Ambient and Cryogenic Temperature Conditions,

Abstract

The transonic airfoil CAST 10-2/DOA2 was investigated in several major transonic wind tunnels at Reynolds numbers ranging from Re= 1.3 million to 45 million at ambient and cryogenic temperature conditions. The main objective was to study the degree and extent of the effects of Reynolds number on both the airfoil aerodynamic characteristics and the interference effects of various model-wind-tunnel systems. The initial analysis of the CAST 10-2 airfoil results has revealed appreciable 'real' Reynolds number effects on this airfoil and, moreover, shown that wall interference can be significantly affected by changes in Reynolds number thus appearing as 'true' Reynolds number effects.
