Aerodynamic and Aeroelastic Design of Low Wind Speed Wind Turbine Blades

A large number of wind energy installations exist on rich wind resource sites. Nevertheless, estimates show that about 50% of the world’s wind energy resource has a wind speed of 7 m/s or less. For these low wind speed resource areas, low wind turbine technology is required. For this reason, this DTU Wind Energy master project, in cooperation...

Shape Parameterization in Aircraft Design: A Novel Method, Based on B-Splines

This thesis introduces a new parameterization technique based on the Class-Shape-Transformation (CST) method. The new technique consists of an extension to the CST method in the form of a refinement function based on B-splines. This Class-Shape-Refinement-Transformation (CSRT) method has the same advantages as the original CST method, while also...

Multidisciplinary Design Optimization in the Conceptual Design Phase: Creating a Conceptual Design of the Blended Wing-Body with the BLISS Optimization Strategy

Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...
