Abstract
This paper presents an analysis of morphing trailing edge design of a wind turbine rotor blade with multistable elements embedded inside it. Morphing trailing edge devices are promising candidates for reducing loads in variable wind conditions, turbulent flows as well as capable of changing the shape rapidly. However, conventional actuation systems are quite complex and prone to high maintenance cost. The application of multistable laminates allow large deformations with modest actuation demand without the need for a continuous supply of energy. The multistable plates undergo snap-through with the help of mechanical forces and with Macro Fiber Composite (MFC) actuator patches. A parametric study is conducted to study the best location of the MFC patches to allow snap-through with lower voltages than straight fiber laminates without losing bistability. The multistable rectangular plate with variable stiffness (VS) laminates is then embedded in the flap section to achieve deflection of the flap as the multistable plate snaps.
