A downwind morphing rotor that exhibits bending loads that will be reduced by aligning the rotor blades with the composite forces. This reduces the net loads on the blades which therefore allow for a reduced blade mass for a given maximum stress. The downwind morphing varies the amount of downstream deflection as a function of wind speed, where the rotor blades are generally fully-aligned to.

YawDyn simulates e.g. the yaw motions or loads of a horizontal axis wind turbine, with a rigid or teetering hub[11]. Finally, this thesis will serve as an aid and a step towards the design of a more lightweight blade and hope that it will serve as a tool that will aid the design of new wind turbine blade composite material.

In this research, Blade Element Momentum theory (BEM) is used to design a HAWT blade for a kW horizontal axis wind turbine. The airfoil is RISØ-A, produced by RISØ National Laboratory.

KNOW-BLADE TaskTechnical Report R, Riso National Laboratory Roskilde -DK, June The flow field past the rotating blade of a horizontal axis wind turbine has been modeled with a. Unlike the conventional windmill with its horizontal axis, this is a vertical axis rotor linked to a kW generator.

The experiment is designed to test the feasibility of similar windmills with a larger capacity, and also the possibility of storing wind energy in the form of compressed air.

Though wind turbines and windmills have been used for centuries, the application of rotor aerodynamics technology to improve reliability and reduce costs of wind-generated energy has only been pursued in earnest for the past 15 years. This paper provides an overview of recent research and development pertaining to the aerodynamics of the horizontal-axis wind turbine rotor.
