Design, Engineering and R&D

Our Design, Engineering and R&D division in Bengaluru, India and Hamburg, Germany houses some of the best brains in the Industry. The center has the capabilities and capacity to upgrade existing wind turbine designs and to develop future turbine designs. Its core competencies are in the area of overall turbine design, system integration, subsystem and component design.

The key activities undertaken are covering activities in the area of system engineering and industrialization for entire wind turbines in the range of 2 MW up to 6 MW for onshore turbines. The wind turbines being developed are of the type horizontal axis machines with 3 bladed rotor and are covering the following subsystems and components:

  1. Rotor with blades, hub and pitch system
  2. Drive train with gearbox, shaft, bearing and coupling
  3. Energy conversion with generator, converter, cables and transformer
  4. Buildings and main structure with mainframe, yaw system, tower and foundation
  5. Auxiliary systems with lubrication, cooling and hydraulic
  6. Control system
  7. SCADA





The system engineering activities are covering the design, certification, testing and vendor qualification of the respective subsystems of the wind turbine as described above. For the development of wind turbines, a lean development process is being applied, which splits the development projects into different milestones and stage gates. Proper technical risk management and project risk management is applied for all project stages. The verification and validation activities follow the famous V-model approach, which is being used across industries.
The industrialization activities undertaken by the research and development center are covering the serialization of the respective products, subsystems and components. This includes the delivery of bill of materials, documentation, drawings and test reports. The industrialization also includes the flawless and failure free product introduction, covering the built of engineering prototypes, production and installation tool design, non-conformity management, localization and value chain optimization.
