Eppler's code overpredicts moment coefficient and can not predict maximum lift and lift curve in post stall region.
The resulting yaw brings the left wing forward, decreasing [alpha] and thus bringing it back to the front side of the coefficient of lift curve and increasing lift.
The lift curve diagrams show that the wing's lift increases as the AOA also increases until the airflow over the upper surface of the airfoil is disrupted, and the wing's lift is destroyed.
A valvetrain module includes several utilities, such as one for optimizing existing lift curves based on velocity, acceleration and jerk.
Model development: In the early days of modeling, circa 1995, management's attention was occupied with mastering the math and pursuing powerful "lift curves." New generations of models have reached new levels of complexity and reflect dramatic changes in the business over the last decade.
