• PROPID Run: wt04a.in

• Baseline Power Curve, No Iteration

New rotor

• wt04a.in & wt05a.in Example of 1-D Newton Iteration

• New rotor

2-D Newton Iteration Iteration)

• PROPID Run: wt06a.in

• Rotor Scale  Peak Power (500 kW)

• Rotor RPM  Tip Speed (150 mph, 220 ft/sec)

500 kW

Peak Power

AEP = 694 MWh/yr

Lift and Axial Inflow Specifications (Multidimensional Newton Iteration)

• PROPID Run: wt07a.in (analysis only)

• Rotor Radius Same as wt06a.in (39.9 ft)

• Variable Speed Turbine Design, TSR = 6

• Power Curves Newton Iteration)

• AEP 790 MWh/yr (wt07a) vs 694 MWh/yr (wt06a)
