Carter - Model 500 -Medium-Size Wind Turbines

The CWE Model 500-36.6wind turbine is a unique,portable,self-erecting wind turbine designed for remote, extreme environment locations that are not viable usingconventional wind turbine technologies.The CWE Model 500-36.6wind turbine is designed forharsh tropical and artic conditions. The turbine is compact and portable, with easy shipping. The complete turbine assembly is shipped quickly in standardizedcargo containersanywhere in the world and can be erected in one day.Recognized globally as an industry leader and pioneer of the two-blade wind turbine design, Carter Wind has over 800 turbines installed having accumulatedtens of millions of operating hours

Two Bladed Downwind Teetering Rotor:
Eliminates gyroscopic rotor loads and allows the rotor to achieve rotor lift equilibrium without inducing a moment into the main shaft when airflow between rotor blades is unbalanced or turbulent.

Unique Flexible Composite Blade Design:
Carter’s exclusive composite Flex Beam™ designis torsionally soft to allow blade pitch change,and flexible in the flatwise direction to allow the rotor blades to passively flex up to 60 degrees away from the tower during non-rotating, extreme wind loading events.

Self-erecting, Tilt-up, Guyed Tower:
The Carter tilt-up turbine design does not require cranes for installation or maintenanceand allows formaintenanceto be performed safely on the ground. Additionally, the guyed towerrequires substantially less excavation and concrete for foundations than typical wind turbines as well asless road infrastructure, as roads leading to the turbine need only support a truck.

Variable Speed Stall Regulated:
Peak power output is controlled through aerodynamic stall using variable speed operation without additional equipment being required to change blade pitch with changing windspeedsto control power.

The Carter wind turbine proprietary technology is most significant in that it produces 4 times the energy per pound of equipment weight versus the current state of the art three blade wind turbines.

The capital investment required to manufacture, transport, install, and maintain wind turbines, is a function of equipment weight. More energy with less equipment weight means a lower cost of energy.

The Carter wind turbine design operates on the same aerodynamic principles as conventional wind turbines, but achieves its superior energy to weight and reliability advantage by successfully integrating the enabling technologies of the helicopter industry.
