With the increasing demand for advanced UAVs in the market, high sustainability, reliability, and better workability are the most critical priorities. During UAV operations, accidents are common, leading to severe damage to expensive and vital equipment. A crashworthy UAV structure would help reduce equipment loss, which would lead to safer conditions while flying. The growing requirement for surveillance through onboard cameras dictates stable flying. Hence, we are adopting a hummingbird body, having the best hovering capabilities available within nature. Our research explores the simulations of crash scenarios to understand the collision resistance and crash-energy absorption capability of the hummingbird inspired CAD model. We have identified the sections in a UAV’s fuselage, which carries mission-critical components and found the maximum acceleration at those sections. RADIOSS™ module of Altair HyperWorks™ Software is used to simulate the crashes and to examine the maximum acceleration responses at the vital locations. The 3D printed multi-material composite UAV’s fuselage with strengthening at critical locations made the notable difference in energy absorption of structure and transfer of acceleration on the payload. We found that the specific energy absorption maximized and transferred acceleration on the critical locations reduced up to 8.88% when compared with the initial ABS material. This design methodology is proposed to be used in small UAVs to minimize the crash loads in avian flight-based vehicles.
