The trailing edge of wind turbine blades can be manufactured in an elastic material that makes it possible to control the shape of the trailing edge. This will reduce the considerably dynamic loads ...

A flexible, controllable trailing edge for wind turbine blades has shown that it can reduce the loads on the turbine and in the end provide cheaper electricity from wind power. The idea dates back to ...

ABSTRACT A mathematic rotating blade model is introduced in conjunction with periodic time-varying aerodynamic load, which is described by Beddoes-Leishman dynamic stall model. The consequent ...
