Zusammenfassung:
A novel design methodology for rotors is presented, which enables inverse blade design based on a predefined radial bound circulation distribution, either according to a wind turbine regime (repeller) or a propeller regime. The methodology comprises a pair of algorithms for design and off-design computations that employ the vortex filament method (VFM) amid a combination of a prescribed wake model and lifting line theory (LLT). Particle image velocimetry (PIV) measurements are performed on exemplary rotor designs to validate the theoretically predicted circulation distributions. Experimental results are discussed under consideration of an extended VFM model containing a decambering correction and the conventional blade element momentum theory (BEMT) as a reference model. The methodology has applications in the design and analysis of rotors with a certain load distribution to enable the systematic modification of the local magnitude of the shedding vortex sheet in the rotor wake.
