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.

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.

CFK-Waveguide- Antennas

Fraunhofer Institute for Surface Engineering and Thin Films IST

The Fraunhofer IST presents waveguides consisting of metallized carbon fibre reinforced plastic (CFRP) for antennas of earth observation satellites. The requirements for antennas for satellite applications are high: a basic requirement in the aerospace industry is to save as much weight as possible. Conventional antenna materials such as copper are excluded for this reason. CFRP consisting of carbon fibres and resins is comparatively light and strong, but on the other hand it lacks the required electrical conductivity which has become the main focus of the Fraunhofer IST scientists. With a specially developed galvanic process, they succeeded in providing the waveguide with a thin conductive coating of copper inside and outside, which also withstands the extreme temperature fluctuations prevailing in space.

Optical Coatings for Space Applications

Fraunhofer Institute for Surface Engineering and Thin Films IST

In the field of optical coatings for space applications the Fraunhofer IST presents multilayer optical filters on glass or polymers, narrow bandpass filters, edge filters and large area dielectric multilayer beam splitter coatings with low wave front error as well as a high glossy mirror of CFRP which imposes additional requirements are imposed on the base material:. It must not deform, even under the changing temperatures in outer space conditions, and in addition it must meet the optical requirements. To do this, the base material is modified.by the Fraunhofer IST.

Handheld Terahertz test system

Fraunhofer Institute for Industrial Mathematics ITWM

The handheld scanner is a complete Terahertz test system for non-destructive on-site testing. Thanks to its compact, lightweight design, the device is easy to transport, making it ideal for testing immobile specimens, for example, and for use at various test sites in production. A one-sided sample access is sufficient as the system works in reflection. The combination of the sensor with a linear position encoder enables linear examinations of the sample, whereby a depth profile of the samples is determined at each point. In this way, A and B scans of the examined sample are obtained in analogy to ultrasonic examinations. The hand-held scanner is used for non-destructive testing of non-metallic materials. The main focus is the inspection of components made of fibre-reinforced plastics like radomes
