Dynamic Stall Control by Variable Airfoil Camber

open access: yes, 1994
In the present numerical investigations the unsteady flow about a helicopter airfoil section under deep dynamic stall conditions has been influenced by dynamic airfoil deformation.

The Relevance of the Dynamic Stall Effect for Transient

open access: yes, 2005
This article describes a methodology to quantify the influence of dynamic stall on transient fault operations of active-stall turbines. The model of the dynamic stall effect is introduced briefly.

Dynamic Stall Control: A Review

open access: yes
The control of dynamic stall associated with wind turbine and helicopter blades, fixed-wings, flapping wings, as well as alternating flow separation and attachment produced by cyclical control inputs, is reviewed. Different airfoil and wing stall types are described, control metrics are identified, and the generality of harmonic pitch oscillations is ...
