Abstract

In a major cooperative research program within existing US-German and US-French Memoranda of Understandings (MoU's) a very comprehensive experimental study was conducted with a 40-percent geometrically and dynamically scaled BO-105 main rotor operated in the open-jet anechoic test section of the German-Dutch-Wind Tunnel (DNW). The objectives of the program were to improve the physical understanding and the mathematical modelling of the effects of the higher harmonic blade pitch control technique on blade-vortex interaction (BVI) impulsive noise and vibration reduction. A unique set of acoustic, aerodynamic, dynamic response, performance, and rotor vortex wake data were acquired with a pressure and strain gauge instrumented blade and by application of non-intrusive measurement techniques. This report documents the experimental part of this research program, termed Higher-harmonic-control Aeroacustic Rotor Test (HART) which was jointly performed by researchers from.
