How do I get rid of this weird line along the x-axis when importing an airfoil into XFLR5?
You most likely are importing the points with the wrong order.
Usually programs are looking for points to start at the TE and go clockwise along the lower surface to the LE and then back to the TE ...

Are there any sources that contain information on the airfoils of the Boeing 737-500 and 737NG Aircraft?
No, this information is proprietary.
The public information about 737 foils is based on the original -100 model.
Further, it can be assumed that any modern aircraft with sufficient resources behind it ...

Are there studies to find surface treatments to reduce the drag of an airfoil?
Yes, there are literally thousands of studies on the subject. A keyword search on this link brings up many examples. (credit to Sophit)
There's also a similar question on this site that may be ...

Can composite material be used in leading edge of airfoil instead of aluminium through Additive manufacturing?
Lots of aircraft use composite material for their leading edges.
There is no need to use additive manufacturing to accomplish this.
That said, you might be interested in filament winding, automated ...

Moving from 2D wing to 3D wing design
how would we approach it? It is not as if we would try all kinds of combinations of taper ratio and dihedral and compare all of them.
You're right.
Unless you are designing a radically new aircraft ...

Moving from 2D wing to 3D wing design
Sometimes the process may seem direct, but other elements come into play. As an initial part of the process, the designer may have an idea regarding the plane, its weight, and required power. If the ...

Moving from 2D wing to 3D wing design
An aerodynamic engineer would maybe strive for an elliptical circulation. But not an airplane engineer.
In 1933 Ludwig Prandtl published "Über Tragflügel kleinsten induzierten Widerstandes" ...

Moving from 2D wing to 3D wing design
Why wouldn't you try all kinds of combinations? This is one of the fundamental ways design is performed.
Design is inherently an inverse process -- we start with desired performance and work to find ...
