03.1 - Aerodynamics - CFD Methods and ValidationPERFORMANCE IMPROVEMENT OF A COMPOUND HELICOPTER ROTOR HEAD BY AERODYNAMIC SHAPE OPTIMIZATIONP. Pölzlbauer¹, D. Desvigne, Airbus Helicopters, France; C. Breitsamter¹; ¹Technical University of Munich, Germany Within the FURADO project, the aerodynamic design optimization of a semi-watertight full-fairing rotor head for the Racer compound helicopter is conducted by means of CFD simulation. Due to the high cruising speed, aerodynamic efficiency is one of the major challenges within the demonstrator development. The expanded flight envelope represents an important innovation in the rotorcraft domain. |
