Unsteady and Post-Stall Model Identification Using Dynamic Stall Maneuvers

AIAA Atmospheric Flight Mechanics Conference, 2015
The purpose of this work is to identify a high angle of attack model of a turboprop aircraft using data from flight tests. The classic quasi-steady stall maneuver was modified to include elevator inputs during the approach to stall, as an effort to improve the estimation of dynamic derivatives.

Dynamic stall control via adaptive blowing

Renewable Energy, 2016
Abstract An aerodynamic load control concept termed “adaptive blowing” was successfully tested on a NACA 0018 airfoil model at Reynolds numbers ranging from 1.5·10 5 to 5·10 5 . The global objective was to eliminate lift oscillations typically encountered on wind turbine blade sections.

TOWARDS A GENERAL DYNAMIC STALL MODEL

2017
The present study is focused on dynamic stall behavior of a pitching airfoil. The deep stall regime is in particular considered. The final goal is the development of a model able to deal with different types of dynamic stall, including those characterized by vortex shedding. The first steps towards this goal are shown herein.
