The development of multi-stage launch vehicle is the most affordable response to increase the competition and efficiency of complex systems for space access. Nevertheless, each subcomponent has to be designed to exploit any possible weight reduction without compromising the structural performance. In this framework CIRA worked on a new composite structural architecture for space applications, like the inter-stages for space launch systems, named ANISO-GRID structure [1–5]. Thanks to this technology, it is possible to realize the entire main structure in a unique part and, successively partition it into more than one sub-part in order to match the assembly requirements [6]. Generally, each sub structure is connected to the adjacent structural component by means of metallic massive interconnection flanges. The present work aims to design novel interconnecting flanges based on exploiting the benefit of additive manufacturing technologies.

摘要

The development of multi-stage launch vehicle is the most affordable response to increase the competition and efficiency of complex systems for space access. Nevertheless, each subcomponent has to be designed to exploit any possible weight reduction without compromising the structural performance. In this framework CIRA worked on a new composite structural architecture for space applications, like the inter-stages for space launch systems, named ANISO-GRID structure [1–5]. Thanks to this technology, it is possible to realize the entire main structure in a unique part and, successively partition it into more than one sub-part in order to match the assembly requirements [6]. Generally, each sub structure is connected to the adjacent structural component by means of metallic massive interconnection flanges. The present work aims to design novel interconnecting flanges based on exploiting the benefit of additive manufacturing technologies.
