wind turbine with a secondary rotor
Hello. I am new to the program (and I am an electrical engineer). Is it possible to simulate a wind turbine with a secondary rotor, similar to the one in the picture, in qblade?
The essence of such a scheme of a wind turbine is the aerodynamic multiplication of revolutions due to the location in the middle of each blade of the main rotor of the generator, on the shaft of which an additional wind turbine is installed. Due to the high peripheral speed (40-50 m/s), the diameter of the additional wind turbine is 10-15 times smaller than the diameter of the main rotor. Accordingly, the turbine revolutions are 10-15 times greater than the rotor revolutions, which allows to reduce the weight of the generators by the same amount and eliminates the need to use gearboxes (multipliers).

Hi,
modeling secondary rotor attached to rotorblades directly is not possible.
However, I can imagine that using QBlade’s SIL interface, one could run multiple instances of QBlade in a co-simulation setup to address this problem:
- The main rotor would receive the thrust force generated by the secondary rotors.
- The secondary rotors would experience an inflow velocity determined by the main rotor’s RPM and the wind speed distribution.
