Peak power specification for a stall regulated turbine 1 d iteration
Peak Power Specification for a Stall Regulated Turbine (1-D Iteration)

  • 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
    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
    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)
