Help. Whath airfoil is this!
Hello, does anyone know which airfoil this is? To see if I can generate it with profili or any other program. Thanks in advance

Look here for the real Clark Y. Your drawing looks like a Clark Y thickened in a way that the flat bottom part is unchanged, basically by raising the center line by a fixed percentage and thickness (and LE radius) by the same percentage. It might be possible to do that in Profili. Unfortunately, you clipped the picture so that the airfoil's length is not visible and thickness in % can't be measured (my guess is 17%).

Thank you very much for your answers I attached a full profile image

It may not be any specific named airfoil.. People have been calling any flat bottomed airfoil a "Clark Y" for over 75 years. You could argue that it is in fact, semi-symmetrical with a straight lower section. A lot of model wings are designed using a rib with a flat section because it makes building the wing easier. There are a lot of models out there with TLAR airfoils.
