Abstract:

Wind turbines blades of propeller type are made according to various blade profiles such as NACA, LS, and LM. There are many factors for selecting a profile. One significant factor is the chord length, which depend on various values throughout the blade. In this work a NACA 4412 profile was created using DESIGN FOIL software to obtain the coordinates of a wind turbine blade in PRO/E. Aerodynamic analysis was done on the created design. Maximum lift to drag ratio was calculated by varying angle of attack of the blade. To find a suitable composite for wind turbine blade, Modal and Static analysi

Wind turbines consists of three key parts, namely, wind wheels (including blades, hub, etc.), cabin (including gearboxes, motors, controls, etc.) and the tower and Foundation. Wind turbine wheel is the most important part ,which is made up of blades and hubs. Blade has a good aerodynamic shape, which will produce aerodynamic in the airflow rotation, converting wind energy into mechanical energy, and then, driving the generator into electrical energy by gearbox pace.

Abstract:

The blade is the most critical part of turbine design because it is used to convert kinetic to mechanical energy. In general, the blade types used for ocean wind turbines are taper and taperless blades, like those operated at Ciheras Coastline. Previous research has been analyzed the type of airfoil used in designing taper blades for ocean wind turbines using NACA 4412, which was selected as the optimal foil configuration at sea wind speeds of 12 m/s. In this study, the comparison of taper and taperless blade designs using NACA 4412 at a wind speed of 12 m/s is analyzed. The comparative study

Abstract:

The main purpose of this paper is to demonstrate a bionic design for the airfoil of wind turbines inspired by the morphology of Long-eared Owl’s wings. Glauert Model was adopted to design the standard blade and the bionic blade, respectively. Numerical analysis method was utilized to study the aerodynamic characteristics of the airfoils as well as the blades. Results show that the bionic airfoil inspired by the airfoil at the 50% aspect ratio of the Long-eared Owl’s wing gives rise to a superior lift coefficient and stalling performance and thus can be beneficial to improving the performance o

Abstract:

This paper presents a new design procedure for large wind turbine blades, which can be used in various case studies. The structural design of 2MW CFRP blade was performed using a verified 2MW GFRP blade model. The structural integrity assessment of the CFRP model demonstrated that the design criteria for tip deformation, buckling failure, and laminate failure in normal wind turbine operating conditions were met. The existing aero-elastic analysis code was not used to estimate the blade load, but the blade’s surface pressure was calculated using CFD. The conventional load analysis code necessit

Abstract:

Effects of tip losses, hub losses, amended attack angle, and amended thrust coefficient are taken into consideration to analyze aerodynamic performance of wind turbine blades based on the blade element momentum (BEM) theory. Based on amended calculation of BEM theory, a program code is developed by software named Matlab. Using a 1500kW wind turbine as an example, aerodynamic information, performance coefficients and blade load distributions are calculated. Compared with the well-known international wind power design software called Garrad Hassan (GH) Bladed, the results have good consistency,

In recent decades, the rapidly development of wind energy in China and the increasing of size and complexity of wind turbine have requested the improvement in wind turbine systematic design technology. A reasonable systematic dynamic model is an important part for systematic design of MW-class wind turbine. In structural dynamic model, the flexibility of blade and tower is represented by presumed mode shapes.
