ABSTRACT OF INVENTIONThe main objective of this invention is to design and build a hybrid-powered Unmanned Aerial Vehicle (UAV), by leveraging advanced 3D-printing technologies. Our invention achieves higher performance efficiency and at lower manufacturing time and cost. Our invention employs a modular design approach for sub-assemblies, so that they can be rapidly removed and replaced as and when required onsite. This obviates the need for extensive repairs or maintenance and spares storage. Our invention”s design and construction of components provides for self-aligning and self-assembling slots, snap-fit joints and notches, which allows for consistent high-fit and rapid assembly, with low skill and tool requirements. Our UAVs have fossil-fuel powered engine as well as solar panels, which gives the UAV additional endurance and batteries can be use as the secondary backup system. Design of components and structures is light-weight and self-assembling. Energy Sink built into the module absorbs energy from impact and crumbles, preventing energy from transmission further into the structure and hence restricting structural damage. Our invention is capable of autonomous vertical takeoff and landing, with high-endurance and carrying sophisticated payload. Since the UAV is almost entirely 3D-printed without using any tools, jigs or fixtures, the design-to-manufacture time and cost are greatly reduced compared to conventional method. Also, our invention uses aerospace-grade material in 3D-printing, so the mechanical properties, weight to strength ratio and heat deflection are comparatively higher.
