I included some questions for Topic 5 into another issue on accident.

Weston-Pace commented 2 years ago

Are cambered airfoils better at low speeds if we want to generate the most lift?

Weston-Pace commented 2 years ago

Can planes rotate their wings without having to turn their whole body in order to generate the most effective angle of attack?

Weston-Pace commented 2 years ago

Why does the complex step method use imaginary numbers in order to calculate the coefficients and derivatives of the polars.

Weston-Pace commented 2 years ago

Is it normal for the derivative polars to be so noisy. I assume that they will be since it completely numerical, and the coefficient values by which the derivatives are found are also numerical. Good things can be found from the derivative polars, though. It can be seen that the linear region of different airfoils has a slope of 2pi for the coefficient of lift.

Weston-Pace commented 2 years ago

Additionally, the derivatives can show us how fast the coefficient of lift changes after stall (i.e. the steepness of the graph)
