VAST AUAV (Variable AirSpeed Telescoping Additive Unmanned Air Vehicle)

摘要

A low-cost, highly flexible and modular Variable AirSpeed Telescoping wing Additive manufactured Unmanned Aerial Vehicle (VAST AUAV) for atmospheric sensing is presented. A novel aerodynamic design was realized with a lightweight, efficient additive manufactured (AM) mechanical structure to meet performance requirements. The aerodynamic design features telescoping wings to permit both dash and loiter flight depending on the exposed wing area and airfoil. The aircraft structure was primarily fused deposition modeling (FDM) ABS-M30 with supplemental carbon fiber spars and commercial off the shelf (COTS) fasteners. The total weight of the aircraft was 7 lb (3.2 kg) with a maximum wingspan of 80 in. (2 m). The structure was designed to be easily assembled using only standard hand tools. The modular design permits rapid reconfiguration of the aircraft and the ability to swap payload while simplifying replacement of damaged pa时s ，even in the field. Focus on frangible design prevents widespread damage and minimizes rebuild in the case of failure. Several test flights were completed demonstrating the structural integrity of the AM parts and the success of the overall design.
