UAVs (Unmanned Aerial Vehicles) have been developed to perform various military and civilian applications.
The present research is motivated by the need to develop a fast adaptable UAV design technologies for agile, fuel efficient, and flexible structures that are capable of adapting and operating in any environments.
The objective of this research is to develop adaptive design technologies by investigating current design methods and knowledge of deployable technologies in the area of engineering design and manufacturing.
More specifically, this research seeks to identify one truss lattice with the optimal elastic performance for deployable UAV wing design according to the Hashin & Shtrikman theoretical bounds.
We propose three lattice designs - 3D Kagome structure, 3D Pyramidal structure and the 3D Hexagonal Diamond structure. The proposed lattice structure designs are fabricated using an Stratasys Objet350 3D Printer while the material chosen is a polypropylene-like photopolymer called Objet DurusWhite RGD430.
Based on compression testing, the proposed inflatable wing design will combine the advantages of compliant mechanisms and deployable structures to maximize flexibilities of movement in UAV design and development.
