This section is about the aerodynamic body of the turbine.

Many small wind turbines do not have an aerodynamically efficient shape. Our HOLI 300 however was developed for minimum resistance to the wind to ensure minimum forces on the turbine body while maximizing power output. The aerodynamic body of the HOLI 300 consists of two main parts, nacelle and spinner. In this section the development and the manufacturing of these components are shown.

Aerodynamic Body Parts

  • Spinner
  • Nacelle

Articles about the Aerodynamic Body

Turned spinner

Spinner Manufacturing

In this article we describe how we manufactured the small wind turbine spinner for our turbine. We used a mould , epoxy, putty, a gelcoat and glass fiber.
Nacelle Manufacturing

Nacelle Manufacturing

We used glass fiber and epoxy to manufacture the aerodynamic nacelle for our small wind turbine. We also used plywood and styrodur to make a mould.

He is developing structural design optimization technology to accelerate the design process for wind turbines, with specific application to material efficient structures (e.g. guyed or jacket structures) and mass-customization (e.g. site-specific foundation design). He holds advanced degrees in Wind Engineering and Manufacturing. Before relocating to Germany and transitioning to wind energy research in 2011, Robert worked in mechanical engineering and operations management roles at automotive supplier BorgWarner in the USA and in Asia. His interests are triathlon, kitesurfing, and coaching HOLI’s successors: the 2015 Flensburg student small wind turbine team!
