Additive manufacturing for airship

Among air vehicles, the airship has several major advantages; mainly a significantly higher flight time for the same energy and a low weight to payload ratio, which makes it particularly suitable for many applications, namely those close to the ground at low speed. It is also very safe to use, which is of particular importance for applications involving interactions with humans. For any aerostat, most of the mass is concentrated at the surfaces of the enclosure containing the gas, which must have a very low surface density.
This does not present any problem for a flexible membrane, but the realization of envelopes that are at the same time leak-proof, rigid and sufficiently light has only been possible in recent years, thanks to the emergence of high-tech materials. Micromeshes belong to this category. Micromeshes have low densities thanks to a network of interconnected rods that provide stiffness (strength) to weight ratios and energy absorption superior to all other types of ultralight materials. These materials could be obtained by the combination of polymer 3D printing and methods allowing the mechanical assembly of several parts. It will also be necessary to consider the cohesion of the micro-lattices with a leak-proof envelope to obtain an airship. This project consists of developing a semi-rigid shell manufacturing procedure based on micromeshes for the design of airship enclosures.
