Kurzfassung
In the framework of a major European cooperative research programme on rotorcraft aerodynamics and accoustics (HELISHAPE) a parametric model rotor test was conducted in the open test section of the DNW using the MWM test rig of DLR and a highly instrumentated model of a fully articulated ECF rotor equipped with blades of advanced design and two exchangeable blade tips. One set of balde tips (7A) was of rectangular shape, the other one (7AD1) of swept-back parabolic/anhedral shape. the main objectives of this experimental research were (1) to evaluate noise reduction techniques (conceptionally by variation of rotor speed, dedicated tip shapes and advanced airfoils as well as operationally by identifying low BVI noise decent procedures) and (2) to validate the partners' individual aerodynamic and aeroacoustic codes developed or improved in other tasks of this research programme. A comprehensive set of simultaneous acoustic.
