Nope, its a catapult but at the same time it is a trebuchet as well. Think quadrilateral -> square. Catapult is the generic term.
I would argue it is a trebuchet because it is essentially using the tubing to act as a weight.
Also, very slick, makes me wish I had known how to do that sort of thing during high school.
