Advantages

• One of the most common engineering issues with wind turbines stems from the “eigen frequency” which is defined as the vibration frequency of a - quantum system - in other words, the frequency at which a system will vibrate.
• GC China's deign utilizes a proprietary "Teeter Hub" which dampens passive yaw thus solving the dynamic problems in the structure and is a key to operational longevity.

An Assembled 2-Bladed Wind Turbine

• Achieves lower weight and lower cost
• Load and fatigue analysis is more complex and thorough than 3-bladed
• Zero difference in conversion of wind energy to electricity compared to 3-bladed systems
• Greatest potential is aimed at future remote offshore environments.　　

Internal Structure of 2 & 3 bladed Wind Turbines

• Rotor and nacelle can be assembled on ground then lifted as a unit to the tower.

• 2-bladed design, obvious saving of one blade
• Integrated gearbox, no main shaft and main bearing
• Soft tower is lower weight over traditional 3 blade designs

Cabinet in nacelle is insulated against low temperature with two independent heating elements in the integrated gearbox for easy start in cold climates.

• Compact drive train, stall control, very few components
• 0.8m wide passage all-round in the nacelle for easy maintenance
