Full scale rotor blade deformation measurements in comparison with aeroelastic simulations based on measured high-resolution wind fields

Autor: S Lehnhoff, Joerg R. Seume, Martin Kühn, M F van Dooren, A.P. Kidambi Sekar

Publikováno v: Journal of Physics: Conference Series 1618 (2020), Nr. 5

Aeroelasticity is one of the biggest challenges in wind turbine rotor design, as the length of rotor blades increases which comes along with a slenderer design. The knowledge of the aeroelastic turbine behavior is of great importance. A comparison to

Set-theoretic control of a wind turbine

Autor: Hure, Nikola

This thesis discusses the set-theoretic methods for constrained control of high-order systems. Specifically, focus of the thesis is given on the operating envelope protection and constrained time-optimal control design in the algebra of polyhedral se

Novel controller design demonstration for vibration alleviation of helicopter rotor blades

Autor: Fatma Demet Ulker, Fred Nitzsche

Publikováno v: SPIE Proceedings.

This paper presents an advanced controller design methodology for vibration alleviation of helicopter rotor systems. Particularly, vibration alleviation in a forward ight regime where the rotor blades experience periodically varying aerodynamic loadi

Identification of Aeroelastic Parameters for Cormorant Tail Rotor Structures based on Vibration Measurement in the Stationary Frame

Autor: Viresh Wickramasinghe, David Zimcik, Yong Chen

Publikováno v: 53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference20th AIAA/ASME/AHS Adaptive Structures Conference14th AIAA.

The teetering tail rotor of the Canadian CH-149 Cormorant helicopter fleet experienced limit cycle oscillation (LCO) phenomenon in certain adverse flight conditions in which the transient high amplitude vibration resulted in significant increase of d

Investigation of site-specific wind field parameters and their effect on loads of offshore wind turbines

Autor: Benedikt Ernst, Jörg Seume

Publikováno v: Energies; Volume 5; Issue 10; Pages: 3835-3855
Energies 5 (2012), Nr. 10
