Abstract

In the framework of a major European research programme on rotorcraft aerodynamics and acoustics (HELISHAPE) a parametric model rotor test was condicted in the open test section of the DNW using the MWM test rig of DLR and a highly instrumented model of a fully articulated ECF rotor equipped with blades of advanced design and two exchangeable blade tips. One set of blade tips (7A) was rectangular, the other one (7AD1) of swept-back parabolic/ anhedral shape. The objectives of this experimental research were to evaluate noise reduction techniques (conceptionally by variation of rotor speed, dedicated tip shapes and advanced airfoils as well as operationally by identifying low noise - BVI-minimizing decent procedures) and to validate the partners aerodynamic and aeroacoustic codes. A comprehensive set of simultaneous acoustic and aerodynamic blade surface pressure data as well as blade dynamic and performance data was measured. In addition, valuable.
