This video highlights the design, manufacturing, and testing Charlie, the Turbo Jet UAV.
California State University Long Beach Mechanical Engineering Senior Design Project, brings you Charlie, a twenty-pound carbon fiber UAV powered by a 33-pound-force turbo jet engine, capable of carrying a ten-pound payload.
Four layers of two twill carbon fiber formed the main bottom layer of her NACA 2412 air foil using a plastered 3d printed mold. Seven Burch wood ribs were manufactured with a CNC to form her lateral support as well as structural reinforcement for the wind flaps. The carbon fiber lay also formed her D-box spar by wrapping the layup around a 3d printed lip that seconded as a gluing surface. A gradient focus reinforcement of eight and six layers of carbon fiber spread form the center of her fuselage.
