    The above graph and corresponding table below illustrates results from an Interactive Boundary Layer analysis determining parameters such as Drag, Lift-to-Drag Ratio, Propulsive Power, Turbine Output Power, Sail Thrust Required, Efficiency per Point of Sail, Levelized Cost of Energy (LCOE), 10 year Return-on-Investment (ROI), and Investment Rate of Return (IRR), amongst many others. Integrated Power Technology Corporation™ has developed this model to facilitate optimization of design and operational trade-offs of the Turbofoil®.
