Abstract Bio-inspired micro-air-vehicles (MAVs) usually operate in the atmospheric boundary layer at a low Reynolds number and complex wind conditions including large-scale turbulence, strong shear, and gusts. We develop an open jet facility (OJF) to

Pitching turbine blades into the wind increases the thrust coefficient, $C_{T}$ , which increases the power generated by the wind turbine. However, excessive $C_{T}$ increments beyond rotor mean wind speed $C_{T}$ -equivalent, tend to cause overexert
