Additive manufacturing technologies are emerging as a process to machining for small series, complex and costly parts allowing reduction in cost and time. The combination of issues (fabrication of unique products, short series, need for weight reduction through topology optimization) makes AM processes attractive for developing a large family of metallic parts for launcher and satellite applications. Space-flight hardware design involves complex geometries that can be produced by AM.

A systematic implementation of lessons learned for the definition and specification of projects is currently missing and relying on availability of experienced engineers in the early design phases. This jeopardizes the possibility to prevent production delays generated by specific requirements and design solutions adopted in the early project phases.

Light-trapping helps enhance the light absorption in space solar cells and hence enables their thickness to be reduced to increase the radiation hardness. We have optimised light-trapping structures (LTS) inspired in the diatom frustule and moth’s eyes. As a solar cell reference, we use the commercial 3G30C model from Azure Space Solar Power GmbH. We have developed a physical model to describe the solar cell absorption and derive the efficiency. The optical description relies on the Fourier modal method and the solar cell performance on the detailed balance limit.

The structures will be composed of thin-walled composite deployable booms with CFRFE (Carbon-Fibre Reinforced with Flexible Epoxy) tap-spring hinges. These tape-spring hinges will be part of the CFRP struts forming the deployable structures. The partial use of flexible epoxy resins in the CFRP hinges can introduce an efficient damping in the deployment that can guarantee a controlled maneuver.

The definition of the On-board Software Reference Architecture (OSRA) has led to the definition of a main model (the architecture itself, defined in OSRA), supported by other models focusing on specific aspects such as real-time, transaction, bus exchange, etc. or making the link with system such as the Spacecraft Data Base. The space system primes and space software providers have been starting to use various modelling languages (UML or DSLs) and various tools to support their in-house tailored software engineering processes.

The space industry and space agencies have been aware for quite some time of the interest and added value of model-based system engineering (MBSE) in streamlining the design, development, deployment and verification of space systems. There have been many initiatives during the past decades aiming at defining models and tools able to support the various needs of the system engineering process. MBSE is increasingly being used in operational projects and the next step is to use MBSE extensively throughout the system life cycle, across disciplines and throughout the supply chain.
