Airfoil Blender for Blade Optimizations

Integrated airfoil and blade design method for large wind turbines

This paper presents an integrated method for designing airfoil families of large wind turbine blades. For a given rotor diameter and tip speed ratio, the optimal airfoils are designed based on the local speed ratios. To achieve high power performance at low cost, the airfoils are designed with an objective of high Cp and small chord length. When the airfoils are obtained, the optimum flow angle...

Blender for robotics and robotics for Blender

Computer animation and robotics have most of their mathematical foundations in common. So, Blender is a natural (but still undiscovered and imperfect) GUI candidate for robot simulation and programming. The robotics research community lacks an advanced graphical tool such as Blender, but, on the other hand, it has more advanced and efficient algorithms than Blender for the physically realistic ...

Optimizations of Airfoil and Wing Using Genetic Algorithm

The present study demonstrates how the Genetic Algorithm (GA), coupled with the CFD solvers ARC2D for 2D and KTRAN for 3D problems, can successfully be applied to the airfoil and wing aerodynamic drag minimization. The geometry of airfoil and wing sections is represented by a B-spline curve. The actual values of the coordinates of the control nodes for the B-spline curve are designated as the d...

Bionic Design of Wind Turbine Blade Based on Long-Eared Owl's Airfoil

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 airfoi...
