aerodyn

aerodyn engineering is an independent wind turbine engineering company
and consultancy based in Büdelsdorf in Northern Germany. The company has been
founded in 1997 to hold and use all patents of the inventor and physicist Sönke
Siegfriedsen. Meanwhile several hundred patents are in the companies’ knowledge
database. In addition to this function the SCD Technology as a new and highly
innovated project become part of it. Currently the major project is the
development of the SCD Technology turbines in different sizes for different
ambiences and applications. Started in 2013 with a first idea how to develop a
new technology for floating offshore wind aerodyn engineering gmbh took several
steps to design and validate the SCDnezzy Technology. During development
processes technology and material validation is essential to provide a valid
technology evaluation. Starting with feasibility studies for the concrete
foundation and its sea keeping behavior, followed by small scale model tests in
wave basins and an open sea test aerodyn engineering gmbh is able to combine
turbine design experience with a new floating foundation technology for a
competitive market solution.
Based on this experience aerodyn engineering contributes as industrial
partner to the “HyStOH” project responsible for the wind turbine development
and integration into the tower structure. The SCD-Technology is a fully
integrated lightweight drive drain concept providing a lightweight wind energy
converter resulting in a reduced system mass for the tower and foundation
structure.
Starting the project aerodyn engineering provides a turbine load
assessment as initial load limit for the tower top connection. First
investigation area is the rotor orientation, turbine capacity, number of
blades, rotor diameter, hub height and type class. Additionally RNA
(Rotor-Nacelle-Assembly) mass data are provided as well. This data are used for
structural pre-design for tower and foundation. Aerodynamic loading is used to
validate other simulation environments enabling a fully integrated design and
engineering process. Based on this initial data more detailed turbine data are
provided to support the validation process of high-fidelity modeling of other
project partners. A dedicated validation phase is supported by aerodyn
engineering focused on comparable simulation results for all project partners.
Main scope of work for aerodyn engineering is the design of a RNA based
on the derived loads in a fully coupled simulation environment considering aero
elastics, hydrodynamics, structural behavior and the wind turbine control. The
results are feed into the design process for the tower-nacelle interface,
gearbox, generator, rotor hub and rotor blade design. Finally a concept for the
drive train arrangement and the rotor blades will be derived considering the
floating specific controller requirements to enable a fully operational wind
turbine on the HyStOH floating foundation. The design considers site specific
environmental loadings including operational loads and survival conditions.
