This paper presents the design and manufacturing of a high speed jet powered UAV which is capable of flying at M=0.5. Flight time of the UAV is 30 minutes at 1700 m above sea level. Aerodynamic and structural design of the UAV is conducted for 6g sustained and 9g instantaneous loads. Low aspect ratio blended wing-body design is decided due to low drag and high maneuverability. Structure of the UAV consists of the composite parts such as frames and skin and mechanical parts such as landing gears which are from aluminum and steel, engine holders, parachute release mechanism and etc.
