Concept plane

This is a plane that I made to try to get a little bit better at designing with surfaces. My idea was to make a supersonic plane with forward sweep wings, but I don´t now much of aerodynamics yet so I just tried to make it look cool. The fuselage is a Sears Haack body, and the hole for the engine has de aproximate size of a GE 414. The wing profile is a random supercritical airfoil. I uploaded the original Catpart, a igs from that catpart and a igs of half of the plane without the engine hole.
