Abstract

A new facility has been designed and constructed at the University of Notre Dame to investigate dynamic stall and compressible dynamic stall on a 2-D pitching airfoil at high subsonic Mach numbers. The design of the compressible dynamic stall test facility was focused on achieving test conditions that have not been studied previously. The facility is able to pitch an airfoil at non harmonic frequencies at flight Reynolds numbers. The data acquisition system is capable of simultaneously acquiring the pressure data from 31 flush mounted absolute pressure sensors and the position data from an angle encoder. Benchmark data was taken and discussed. It was found that the transition from dynamic stall to compressible dynamic stall had interesting characteristics.
