Investigation of oscillating cascade aerodynamics by an experimental influence coefficient technique [PDF]
Fundamental experiments are performed in the NASA Lewis Transonic Oscillating Cascade Facility to investigate the torsion mode unsteady aerodynamics of a biconvex airfoil cascade at realistic values of the reduced frequency for all interblade phase ...

Analysis of extremum seeking control for wind turbine torque controller optimization by aerodynamic and generator power objectives [PDF]
Wind turbines degrade over time, resulting in varying structural, aeroelastic, and aerodynamic properties. In contrast, the turbine controller calibrations generally remain constant, leading to suboptimal performance and potential stability issues. The calibration of wind turbine controller parameters is therefore of high interest. To this end, several

Unsteady aerodynamic analysis of space shuttle vehicles. Part 1: Summary report [PDF]
An analysis of the unsteady aerodynamics of space shuttle vehicles was performed. The results show that slender wing theory can be modified to give the potential flow static and dynamic characteristics over a large Mach number range from M = 0 to M 1. A
