Sometimes functions return too much information, or more than you need/want. To suppress some of the output and keep your code clean, you can use a tilde in the place of variables.")

This is the fourth video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We code the airfoil type callback. This edit text box reads in the string of the airfoil that the user wants to compute and plot. After we read in the value of the airfoil, we check to make sure that it is only four digits. If more or less, it displays an error message and makes sure the airfoil cant be plotted.

This is the seventh video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We code the four popup menus that appear in the GUI: Grid Type, Trailing Edge, Plot As, and Save Style.

What are flap track fairings and what purpose do they serve on an airplane? These canoe-shaped pieces house linkages and mechanisms that connect the flaps to the wing. As an added bonus (if designed correctly), they can help decrease the wave drag by something known as area-ruling.

In order to use Croccos Theorem for the Taylor-Maccoll problem, it is necessary to show why the total enthalpy along a streamline is constant (within the given assumptions). We start with the energy equation couched in terms of the total enthalpy, and reduce the equation with our assumptions from a previous video in this series. The final result will be used in the derivation of Croccos Theorem.")
