Wind Turbine Power Curve Lab (2D)

A Canvas2D companion that computes real aerodynamic power output — 0.5·ρ·A·v³·Cp, capped by rated power and gated by cut-in/cut-out limits — instead of only animating a spinning rotor.

This 2D companion replaces the 3D version's decorative rotor with the actual aerodynamic power equation, P = 0.5·ρ·A·v³·Cp: drag wind speed, rotor diameter, power coefficient (Betz-limited below 0.593) and air density, and watch instantaneous power, capacity factor, daily energy and rotor RPM update from those formulas in real time, with cut-in (3 m/s), rated (12 m/s) and cut-out (25 m/s) thresholds shaping the curve the way a real turbine's control system does.

⚙ Under the hood

Canvas2D power-curve lab driven by the cubic wind-power equation, capped at a rated-speed ceiling and gated by cut-in/cut-out limits, with rotor RPM derived from an assumed tip-speed ratio of 7.
