Exhibit Overview

Fraunhofer Space Virtual Satellite – Competences of the Fraunhofer Space Alliance

Fraunhofer Space Alliance

The Virtual Satellite provides a comprehensive overview of the space-specific competences of the Fraunhofer Space Alliance. This idealized satellite contains numerous technologies and components of the Alliance’s 18 member institutes. Apart from the satellite, nanosatellite ERNST, environmental influences like solar flares and space debris as well as terrestrial competences are presented.

Fraunhofer Space Mission Wall

Fraunhofer Space Alliance

Applied Research for Industrial Space Technology

Bringing together the competences of 15 Fraunhofer Institutes, the Fraunhofer Space Alliance conducts applied research in the field of industrial space technology. The sheer technological variety of the participating institutes enables the Fraunhofer Space Alliance to offer its customers a unique range of services. The Mission Wall gives an overview of all Space Missions with participation of one or more members of the Fraunhofer Space Alliance.

ERNST

Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut EMI

Fraunhofer EMI currently designs, integrates and tests the 12U nanosatellite platform ERNST (Experimental spacecRaft based on NanoSatellite Technology). ERNST is compliant to CubeSat requirements and the spacecraft bus is based on demonstrated CubeSat components where possible. The main objective of ERNST is to evaluate the utility of a 12U nanosatellite mission for scientific and military purposes. Possible civil applications: climate research, fire detection, determining temperatures on earth surfaces.

 

Optical Bench

Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut EMI

Multidisciplinary Design optimized optical bench of the ERNST nanosatellite. The component integrates multiple payloads and is design optimized with combining both vibrational and thermal response objectives into a Multidisciplinary Design Optimization model. The sinus- and random response of the component against vibrational excitation from the launch system has been significantly improved. Simultaneously, the thermal compliance has been reduced and the radiator was structurally integrated into the optical mounting system to improve the efficiency of heat transport. The Additive Manufacturing has been carried out on an EOS M400 system in the aluminum alloy AlSi10Mg.

Radiation Qualification for Space Applications

Fraunhofer Institute for Technological Trend Analysis INT

Fraunhofer INT investigates the effects of ionizing radiation on electronic, opto-electronic, and photonic components and systems. INT operates the most comprehensive set of irradiation facilities in Europe and can simulate almost any type of radiation, energy and radiation effect relevant in space. In addition, INT advises companies regarding radiation qualification and radiation hardening.

Radiation Effects on different materials

Fraunhofer Institute for Technological Trend Analysis INT

Fraunhofer INT started a series of irradiation tests with everyday materials in order to illustrate, how gammaradiation affects them. The respective dose rates of radiation range from the common background radiation in Germany to human-lethal dose rates and even to very high dose rates encountered only in accelerators such as the LHC at CERN in Geneva. The samples show the importance of radiation testing of materials for satellites before sending them into space.
