Abstract: The first chapter of this paper represents method of Unmanned Aerial Vehicle (UAV) Launching Device (LD) conceptual design adoption with stress on Elastic (Bungee) Cord LD as representative of widely spread launching devices of a simpler structure. Elastic Cord LD design calculation approach is given in the second chapter, including analyzing the motion on the launch rail of the catapult, analyzing  the elastic cords selection and energetic capability of the cords according to the design requirements. The paper recommends this type of Elastic Cord LD analyses procedure in the early phase of design.
