Active trailing edge flaps are a promising technology that can potentially enable further increases in wind turbine sizes without the disproportionate increase in loads, thus reducing the cost of wind energy even further. Extreme loads and critical d

Wind turbine rotors are getting larger in diameter to increase the output of a single turbine and reduce the cost of energy production. The increase in size leads to complex structure-mechanical effects that have to be considered in order to design t

This experimental load control study presents results of an active trailing-edge flap feedforward controller for wind turbine applications. The controller input is derived from pressure-based lift estimation methods that rely either on a quasi-steady

Abstract The influence of localized nitrogen transpiration on second mode instabilities in a hypersonic boundary layer is experimentally investigated. The study is conducted using a $$7^\circ$$ 7 ∘ half-angle cone with a length of 1100 mm and small

The integration of advanced propulsion systems into the aircraft, and the assessment of their benefits related to e.g. fuel burn, noise emission and potential further measures, is one of the major activities of the Large Passenger Aircraft (LPA) Plat

The aircraft manufacturer Embraer, the German Aerospace Center (DLR), the Netherlands Aerospace Centre (NLR) and German-Dutch Wind Tunnels (DNW) have tested an innovative highly flexible wing within an aeroelastic wind tunnel experiment in the transo

We investigate the flutter behavior of 1) a typical-section OAT15A airfoil with a heave and a pitch degree of freedom and 2) a generic symmetric airfoil of variable thickness equipped with a flexible trailing-edge plate by means of RANS simulations.

In this paper the quantification of nonlinear effects in the gust load prediction of transport aircraft configurations is addressed. Therefore, multi-disciplinary simulations of unsteady gust encounters are carried out based on Reynolds Averaged Navi

This paper aims at assessing the gain in accuracy for T-tail flutter point prediction obtained by a strip theory approach used to enhance common linear potential flow theory based unsteady aerodynamic forces. The common approach neglects unsteady aer
