1.65-2MW Commercial Wind Turbine
Optimized Energy Yield
A wide range of turbine designs are available to suit any kind of wind condition or climate.
The simple robust design of the yaw drive systems, flexible couplings and gearboxes reduce maintenance and operation costs.
The unique design of the hub provides for direct access from the nacells to the hub.
Safe & Reliable
Variable pitch controls, lightning safe design and our exclusive safety lock system protect against system failure during operation.
Airdolphin Mark Zero Wind Turbine
The 1kW Air Dolphin – Extremely Low Mass
The total weight of the Airdolphin is only 17.5kg, meaning the weight per generated watt is just 17.5g — only 1/5 of those for large wind turbines. Thus, the Airdolphin tracks wind better in turbulent flows, resulting in more efficient power generation. Small wind turbines can be installed in various places — general households, rooftops, schools, billboards, or mountain areas. These needs could be safely met at low costs because of the ultra-lightness of the unit.
Wind turbines must be totally flexible to face the forces of nature. Because of the light weight, it can quickly respond to continuously changing wind direction and capture the wind, thereby increasing the amount of power generation. We named this wind-capturing ability “Dynamic Wind Capturability”.
The rudder of the Airdolphin uses the Swing Rudder System, an attitude control system inspired by fish fin. The system can instantly respond to wind direction changes and achieve a more efficient power generation.
The rotor system on the Airdolphin flexibly responds to various wind conditions from the slightest to the strongest, offering efficient power generation. It also frees you from pitch controls.
The two advanced technologies of the rotor:
- Ultra low-mass blades reinforced by long-lasting and rigid carbon-fiber skin which is also used for aircraft wings.
- Multi-Stagger System with optimal conversion efficiency for various wind speeds.
Innovation for Low Noise
The Airdolphin comes with the “Silent Disrupter Blade”. This new blade has a number of thin grooves on its surface, which significantly reduces air flow noise. Our designers were inspired by the wings of owls that enables it to fly silently and unnoticed while approaching its prey.
Robust Body Structure
The robust body construction features a “no screw” assembly, inspired by Japanese traditional craft of “Block Puzzle”. This construction ensures superb resistance to climatic conditions.
When there is no wind, the Airdolphin uses previously generated power to rotate for 10 seconds per minute. This will enable the rotor to start up at a mere 1.5m/s wind, reaching the cut-in point more efficiently. At the same time, the function prevents freezing in cold weather.
A power generator weighing 7.5kg and a maximum 4.5kW power output is used for the Airdolphin, realizing increased power generation and strong regenerating brake performance. The most powerful neodymium iron boron magnet called “NEOMAX” is used.
Data Communication System
The Zephyr Communication System allows you to connect the Airdolphin to the internet. You can also install an optional GPS receiver to the turbine for confirming each unit’s location.
Unique Design – Winner of the Good Design Award 2005
Our original body-design with sleek lines and functional beauty was inspired by wild creatures of nature. Airdolphin’s form represents harmony with the environment as well as the strong presence of the unit itself. As the name implies, our turbine looks alive, eager and ready to catch the wind.
The CO2 emission during Airdolphin’s production is roughly 180kg. It only takes 4 to 5 months to offset this amount through power generation by the wind turbine (avg. wind speed 4.5m/s, based on 0.425kg – CO2/kwh). Beyond this offsetting point, the amount of generated power becomes the amount of reduced CO2; thus contributing to the global environment (from Tokyo University Hirao laboratory’s research data).
