Analysis and test flight of drone frame using space frame structure

Abstract

It is now possible to use aluminum alloy structural materials, which are inexpensive and highly recyclable, for drone bodies that are expected to grow in size in the future. The three-dimensional truss structure makes it easier to use aluminum alloy space frames as structural materials for large drones. As a result of structural analysis during hover flight by CAE, it was confirmed that it has a minimum safety factor of 2.7 and a higher safety factor of 1.5 than that of general aircraft. In the test with the actual aircraft, the flight was stable and there was no deformation, confirming the simulation results.
