For the upcoming 11MW to 15 MW turbine generation the company?developed a pre-design of a 14MW, 111m long TC1B?rotor blade with?a hybrid CFRP-GFRP spar caps to reduce the use of costly carbon fibers to a minimum.?

A modern structural concept, combined with aerodyn’s 30+ years of experience in blade development, lead to a 14MW pre-design for a TC1B site, which can still be adjusted and optimized to account for turbine specific aspects, such as rated power, type class and BCD.?High emphasis was spent on using proven state-of-the-art blade materials and manufacturing technologies.

The company?is currently working on 10MW offshore wind turbines, and the components will go into production in the coming year. The next, even larger generation of systems with around 15MW wait in the wings, which will probably come onto the market in the middle of the decade. The big challenge is the current supply chain and the necessary infrastructure for the construction of these giants.

In addition to rotor blade and complete wind turbine development, aerodyn is offering engineering services, service and consulting for decades.

New offshore projects in deep water require more detailed evaluations. aerodyn has been working on offshore wind turbine developments for more than 20 years. It can be assumed that the floating wind turbine market will expand in the coming years. aerodyn has implemented new software and processes and created its own software. aerodyn thus offers comprehensive offshore aero-hydro-elastic simulations of the overall system with wind turbines, floaters and mooring. The company is?proving the aeroelastic stability of the rotor blade. As an innovative company aerodyn is well prepared.

On floating structures, the turbine is exposed to increased movement and hydrodynamic forces. Currents, waves, anchor loads and misalignment in combination with wind forces influence the overall dynamics and often result in high acceleration forces on the tower head with impact on the drivetrain. aerodyn has had experience in the field of floating wind turbines over the years. They?have conducted studies with different kinds of floating structures. In order to be able to comprehensively analyze the entire system, they also developed our processes further and improved our software tools. Today they?perform sophisticated simulations of our floating wind turbines with HAWC2. They?have developed sophisticated pre- and post-processing software aeroHalo which is available which is available for licensing. On request, they?also offer this service to the clients, tailored according the specific ideas.
