Product Description

Weighing less than *9.5 kg (*2.9 lbs.) with a rotor diameter of only 1.8 m (6”), the Airdolphin GTO is the most efficient and easily installed small wind turbine in its class. Zephyr’s Airdolphin Series is engineered and tested for reliability under every condition, providing years of maintenance-free operation.

Airdolphin Features:

Swing Rudder

Zephyr's patented Swing Rudder System is an altitude control system inspired by a fish tail fin, which allows the turbine to instantly respond to subtle wind shifts for improved power generation.

Rotor

The rotor system seamlessly responds to various wind conditions, offering a high wind-to-power conversion factor by utilizing ultra low mass stiff blades, a multi-stagger blended airfoil blade, and a dynamically balanced blade and hub system. These elements work together to constantly control the rotor speed for maximum power output.

Patented Noise Reduction Innovation

The Silent Disrupter (SD) Blade features numerous thin grooves on its surface, which significantly reduce air flow noise. The design was inspired by the wings of an owl that enable it to fly silently while approaching its prey.

Robust Body Structure

The screw-less assembly of the body is inspired by Japanese traditional block puzzle structure. This ensures precise fitting and superb resistance to adverse weather conditions, requiring minimum maintenance.

Power Assist Function

When there is no wind, the Airdolphin uses previously generated power to rotate for *0 seconds every minute. This lets the rotor start up from a subtle wind and efficiently reach the cut-in point. The function also prevents freezing in cold weather.

Intelligent Power Management System

With original patented technologies, the intelligent power management system (patents pending) realizes consistent blade rotation speed while encountering turbulent gusts. Even during hurricanes, Airdolphin can still deliver stable output power after reaching peak wind speed. This is a crucial attribute for small wind turbines which often face turbulence caused by tall city buildings. When the wind speed exceeds *0 m/s (*4.7mph), Airdolphin continues delivering output power at a reduced rotation speed with no need for cut-out. The outstanding performance is achieved by software driven microprocessors. Airdolphin also has various safety features enabling it to detect adverse conditions for automatic shut down.

Generator

The light-weight generator achieves remarkably high power density with tightly wound coils and powerful neodymium iron boron magnets. These two features combine to implement the optimum duty cycle by electronically damping the rotor.

Life Cycle Assessment

An extensive survey based on Japan’s LCA (Life Cycle Assessment) standards showed that an Airdolphin offsets its manufacturing carbon footprints (**0kg-CO2) with less than three months of operation in Japan at an average wind speed of 4.5 m/s (*1.2 mph).
