Investigation of passive root flaps on HAWT: An experimental analysis of different configurations of root flaps on the performance of Horizontal Axis Wind Turbines

Passive root flaps and in particular the Gurney flaps have been employed for improving aerodynamic characteristics for various applications since the 1970's. The effects of passive flaps on two dimensional airfoils have therefore been studied extensively, however, research on their application to Horizontal axis wind turbine blades (HAWT) is...

Analysis of the flight characteristics of a highly swept cranked flying wing by means of an experimental test

The Flying V is a concept proposed and patented by Benad and Airbus Operations GmbH, which is a flying wing aircraft in the shape of the letter V. Multiple researches already showed promising results, with a 25% increased lift over drag ratio compared to conventional aircraft like the Airbus A350-900. Before research of sub-scale flight testing...
