By VGR I mean variable geometry rotors, where there is a possibility to change a rotor's diameter, twist and piston angles. Is it a new idea of geometry optimization? Is it better to model the systems using classical mathematical methods or rather FEA?
Sir
Your intention is laudable but can you explain the possibility of VGR. Because varying blade inclination is the method I am aware of.Varying Rotor dia inevitably affects the power output of the turbine.I request you to give some thought into this process
thanks for your feedback. Of course it can be used not only in wind power plants or different types of turbines but also in VTOL planes.
Whether the type of application affects methodology or not I think it could be interesting topic for basic research.
Sir
To be sensible,variable rotor geometry will induce drag as far as the only available method is sliding in the the shaft.If you are planning to give a method,you have to make sure the aerodynamics of the turbine is not disturbed i.e inflow should not be affected
