• HyTowering - Optimization of the design of hybrid wind towers and development of a suitable monitoring concept for damage detection and quantification

  To reach the government's plans to extend renewable energies, onshore wind turbines (OWT) need to be more powerful. Nevertheless, the higher wind turbine classes as well as the lack of suitable locations requires higher towers due to the connection between hub height and wind speed.

• WinConFat - Fatigue of materials of onshore and offshore wind energy structures made of reinforced and pre-stressed concrete under high cycle loading

  Due to wind and wave loads, wind turbines (WT) are subjected to high dynamic loads, making their foundation structures and piles prone to fatigue. Up to now, piles in wind turbines and even foundations in offshore wind turbines (OWT) are predominantly built as steel constructions. The efficient application of reinforced and pre-stressed concrete structures in WTs and OWTs is presently hampered by the conservative design concept against fatigue, in particular with respect to high-strength concrete. An update of the design concept having its origin in the 1990ies requires comprehensive fatigue tests on concrete, reinforced concrete and their compounds.

• GAeroFeRo - Geometric Characterization for the Aerodynamic Evaluation of Manufactured Rotor Blades

  Typically rotor blades for wind turbines consist of two GFK respectively CFK based half-shells which are fabricated in sandwich construction. Due to the production process and the large dimension of the rotor blades, significant deviations between the blade geometry and the layout geometry can occur.

• GROWup OPC - Grouted Joints for Offshore Wind Energy Converters under Reversed Axial Loadings and Upscaled Thicknesses

  For a water depth larger than 30 m, which is typical for the German Ocean, support structures of Offshore Wind Energy Converters (OWECs) are preferably built as jackets. Independent of the type of support structure, the connection between foundation pile and support structure is mainly realized by a pile-sleeve connection, which is a steel-grout-steel connection, the so-called grouted joint.

• HyConCast - Hybrid substructure of high strength concrete and ductile iron castings for offshore wind turbines

  The research project "HyConCast - Hybrid substructure of high strength concrete and ductile iron castings for offshore wind turbines" deals with the development of a novel, hybrid substructure for offshore wind turbines. The innovative concept is based on the combination of large-sized, thin-walled ductile iron casting knots with high-strength, light-weight precast concrete pipes customized for the environmental conditions and conditions of use.

• ProBeton - Development and experimental fatigue strength testing of concrete foundation structures for offshore wind turbines

  At present, foundations for offshore wind turbines (OWT) are mainly built as steel constructions. However, compared to steel constructions, concrete constructions have considerable advantages in terms of manufacturing and maintenance costs as well as fatigue strength. This is proved by the history of civil engineering structures (e.g. in bridge and container construction), initially made of steel, but nowadays primarily made of reinforced and pre-stressed concrete.

• Smart Blades - Development and Design of Intelligent Rotor Blades

  In the wind energy industry, there is a trend for rotor blades to increase in size, which are subjected to very high dynamic loads due to the fluctuating and heterogeneous wind field. In the framework of this coordinated research project, three rotor blade concepts are investigated. In those concepts, the rotor blades adapt to the specific inflow conditions by means of a modification of the aerodynamic characteristics in order to reduce structural loads on the turbine.

  The proposed project is an ambitious successor for the UpWind project, where the vision of a 20MW wind turbine was put forth with specific technology advances that are required to make it happen. This project builds on the results from the UpWind project and will further utilize various national projects in different European countries to accelerate the development of innovations that help realize the 20MW wind turbine. DTU is the coordinator of this large project of 5 years duration and with a total of 27 European partners.

• BORA - Development of a computational model for the prediction of underwater noise due to pile driving for offshore wind turbine foundations

  The plans of expanding the production of offshore wind energy within Germany’s exclusive econom-ic zone (EEZ) as well as the resulting construction activities for offshore wind turbine foundations, normally installed by impact pile driving, lead toward increased underwater noise levels. The official limiting values that have been introduced by the German government for the protection of marine mammals often make the use of sound mitigation systems obligatory.

• CRC 880 - Fundamentals of Active High-Lift of Future Commercial Aircraft

  To reduce, despite the increasing air traffic volume, the environmental impact of noise and exhaust gas emission in the vicinity of airports, low-noise and energy-efficient aircrafts with shorter climb and descent phase are the demands for the future. The focus of the DFG- funded Collaborative Research Centre 880 is, among others, on the development of novel high-lift systems. In cooperation with the Institute of Turbomachinery and Fluid Dynamics, the IAL is doing research work in the subproject “Compact Electrical Compressors“ with the aim to develop a directly driven compressor system.
