Workshop on ARTES 11

The Austrian Involvement

29 June 2006

ARTES – FFG ALR Goals

The very good results of the last Council meeting at Ministerial

level reflect the importance that Austria gives to the high-

technological space field in our country.

The financial background behind ARTES in terms of subscription

should mainly:

• Assure the sustainability of the Austrian Space “Players“

• Improve their competitiveness on the ESA and on the commercial market

• LTAs, Supplier chain

Why ARTES 11?

• Support further development of the activities in the field of Telecom

• ARTES 11 will allow our industry and research centres to offer high-level solutions for the on-board segment as well as for the ground segment

• Increase the technological competencies in the niche markets where our industry is represented (incl. downstream).

ARTES 11 – Financial Aspect

Taking into account our subscription at the MC 2005 in Berlin and

our actual „to be allocated“ status, a considerable increase in our

participation in ARTES-11 could be envisaged in order to:

• Support the Austrian industries and research centres in offering innovative contributions to this programme on the one hand and

• cost-effective recurring figure on the other hand.

• Based on sustainable business plans

Austrian Aerospace Potential Contributions

As Equipment Supplier to the Commercial Telecom Market

• On-board DSP such as Data Handling Interface Electronics with the use of mixed digital-analog ASIC (HP, Aeolus, Pleiades, Galileosat)

• On-board Mechanism such as EPPM (Artemis, Eurostar, Alphabus)

• Multi Layer Insulation (most ESA missions)

ARC Seibersdorf research – EP Development

• µN Field Emission Electric Propulsion system (FEEP)Modular nature of the FEEP system allows assembly of several thrusters to accommodate a broad

range of thrust requirements (e.g LISA Pathfinder) at constant, high specific impulse. The single FEEP has reached TRL 9, the modular system is in the qualification phase

•mN FEEP ThrusterTransition from µN range to the mN range by exploiting new manufacturing

technologies. The development of these systems is ongoing and reached TRL 2-3.

• Development of µPulsed Plasma Thruster Systemen (µPPT)

PPTs combine accurate thrust control ability with reliability

and low power consumption. PPTs are flight proven systems. The µPPT system of ARC-sr is in the development phase andexpected to reach TRL 4 in 2007

Thrust range: µN – mNSpecific Impulse: 8000 sHigh thrust accuracy and reliability

Impulse bit: µNs rangeSpecific Impulse: 500 -1000sHigh thrust accuracy and reliability

MAGNA STEYR–MEM LOUVRES FOR THERMAL RADIATORS

Design:

The closing and opening of the louvres wings is performed with

SMA (shape memory alloy) actuators controlled by solar radiation

Seite 9

Features of MEM Louvres (verified by tests):

• Dimension: 530 x 490 mm (radiating area) adaptable to the requirements

• Mass: 498 g/m2

• Heat rejection capability: 86,5%

• Heat leak: 23,9 W/m2 (tbc - test correlation in process)
