Specifications

 

First design is planned to be implemented on a 60kW turbine. Based on a turbine like that, the performance specifications look like this:

 

Specifications of JBRx16-60:

 

 

Rated power

60 kW

 

Rotor diameter

16 m

 

Sweep area

200 sq.m

 

Power regulation

Active pitch

 

Number of joined blades

3

 

RPM

56

 

Wind class

II

 

Relevant standard

IEC 61400-2

 

Cp Value

0,543

 

 

Summarizing these specifications in a power curve model gives this result:

 

Power curve. Conventional vs. JBRx16-60

 

 

 

 

The improvement of production is rather extensive. I.e. is the average energy production (AEP) assuming 6 m/s and a 60kW turbine improved with 18,5%.
