Navier-Stokes-Calculations of the Flow around a Helicopter Fuselage

The purpose of this paper is to briefly describe the BRITE/EURAM HELIFUSE project in its aims and phases, and to present the activities of the Institute for Aerodynamics and Gas Dynamics, Stuttgart University, as contractor of this project during the period 4/97 to 4/98. The project aims at evaluation and improvement of State-of-the-Art Navier-Stokes solvers for prediction of helicopter fuselage drag. The effect of grid refinement is investigated, and some steps in improving the NSFLEX code used at IAG are presented.
