A new design of a Mach-scaled double-swept rotor configuration is investigated by means of unsteady Reynolds-averaged Navier-Stokes computations using the DLR-TAU Code. The investigated rotor frequency of 23.6 Hz results in a Reynolds number of 350,000 and a Mach number of 0.21 atradius. Two highly resolved dynamic stall cases with a sinusoidal pitching are considered and the results are compared to similar numerical computations using a parabolic blade-tip. The flow generated by the double-swept rotor configuration first stalls in the vicinity of the blade-tip, whereas for the parabolic blade-tip the stall process starts further inboard. In addition, the flow field of the double-swept rotor can be separated into two parts: outboard and inboard of the double-swept region. The lift inboard atstarts to stall atand is delayed compared to the outboard region at, where lift stall occurs at.
