If you mean make them based on the NACA design you can go to the Desmos link in the description and I have an interactive airfoil to play with, in there is the equations for the 4-series. If you mean make your own I would suggest reading that NACA document in the description, they outline how they came up with the equations they settled on and it may give insight on how you could create your own.
@@Tidepodious Thanks, I want to make the equations for the surfaces. I want to upload this to computational software where I can plot the equation of the two. Afterwards, I want to find the area between the curves. But I have no idea how to get the topic and bottom curves.
These are parametric equations, so they are in form (x,y). The first half of the expression says where the x point should be and second the y. I prefer to compartmentalize equations but if you were to start with say line 23, and find all of it's variables and plug them in, then do it again for the new unknowns and fully collapse all equations down you should have 4 total parametric equations. (Top first half, top second half, bottom first half, bottom second half). The equations in this form are rather long so be careful not to get lost in the variables.
@@Tidepodious would it be possible if you may make a video tutorial or rundown of the desmos lines? especially the 22, 24, 25. I really appreciate this as a hobbyist

Many thanks ! Using your video I wrote a java program to plot NACA 4 digits airfolils
اشكرك جزيل الشكر استاذ على فيديوهاتك القيمة وارجو منكم ان تقدموا لنا فيديوهات عن السلسلة 5والسلسة 6وشكرا..
Thank you very much for the video
whats the music in the backgroud
What is the value of capital "T" and small "t"
Hello, this looks really cool. How could one make the equations for the upper and lower surfaces?

@@Tidepodious Hey, could you explain line 22, 24, 25 on desmos. I dont understand how a function is being drawn from that
