Aerospace wind turbine generator

What is a rooftop wind generator?

Aeromine Technologies, a University of Houston spinoff, has created a rooftop wind device dubbed the AeroMINE. The Houston-based company claims that their unique “motionless” rooftop wind generators operate more or less silently and occupy only 10% of the roof space, producing up to 50% more energy than an array of solar of the same cost.

What is wind-turbine aerodynamics?

The magnitude and distribution of this force is the primary focus of wind-turbine aerodynamics. The most familiar type of aerodynamic force is drag. The direction of the drag force is parallel to the relative wind. Typically, the wind turbine parts are moving, altering the flow around the part.

What is a wind turbine force?

where P is the power, F is the force vector, and v is the velocity of the moving wind turbine part. The force F is generated by the wind's interaction with the blade. The magnitude and distribution of this force is the primary focus of wind-turbine aerodynamics. The most familiar type of aerodynamic force is drag.

Does Aero-structural design matter for wind turbine rotors?

Optimization of aerodynamic and structural design is critical for an efficient wind turbine rotor design, and especially for extreme-scale (e.g. 50 MW) rotors. In this section, we examine the aero-structural design space to realize an optimal aero-structural design solution for a blade working for 50 MW rotors.

What metric is used to study wind turbine performance?

This paper explores the mathematical models of the aerodynamics of wind turbines, focusing on wind drag and power production. The rst theory, Actuator Disk Theory, provides a metric for studying wind turbine performance as well as an upper-limit for power production, known as the Betz Limit.

How does a drag-based wind turbine extract power?

To extract power, the turbine part must move in the direction of the net force. In the drag force case, the relative wind speed decreases subsequently, and so does the drag force. The relative wind aspect dramatically limits the maximum power that can be extracted by a drag-based wind turbine.
