This paper describes the blind-test CFD activity of the EU 6th Framework project GOAHEAD. This blind-test activity has been used to evaluate and assess the helicopter CFD codes which are today in use in Europe and to scrutinize the wind-tunnel test conditions with respect to the expected flow phenomena prior to the wind-tunnel test campaign. Results are presented for an isolated fuselage test case, a low-speed (pitch-up) test case, a cruise test case, a high-speed tail-shake test case and a highly-load rotor (dynamic-stall) test case.

Abstract

This paper describes the blind-test CFD activity of the EU 6th Framework project GOAHEAD. This blind-test activity has been used to evaluate and assess the helicopter CFD codes which are today in use in Europe and to scrutinize the wind-tunnel test conditions with respect to the expected flow phenomena prior to the wind-tunnel test campaign. Results are presented for an isolated fuselage test case, a low-speed (pitch-up) test case, a cruise test case, a high-speed tail-shake test case and a highly-load rotor (dynamic-stall) test case.
