The SART (Space Launcher Systems Analysis) group has the task of examining all types of future space launch systems and the thereof required engines by means of modern, computer-aided methods. One of the fundamental aims is to reduce the cost of access to space through the identification of eligible technology. Activities range from stand-alone preliminary studies to critical analysis and assessment of foreign concepts. Thanks to integrated vehicle and engine analysis performed within the group, SART fills a unique position in Germany.

The key role played by engines in present and future launchers explains the organisational integration of SART in the Institute of Space Propulsion. Together with its continuous strive to improve simulation techniques, SART also participates in the analysis of new technologies such as the currently investigated ceramic combustion chamber. Another key aspect of SART's role is the professional support provided in the definition of the German space development strategy.

SART holds the system leadership for the ASTRA 2 concept (reusable booster, namely the LFBB, for Ariane 5) and works in close cooperation with industry (EADS Space Transportation, MAN and KT) as well as with DLR Institutes in Braunschweig and Lampoldshausen on the initial outline that makes further steps in RLV development possible.

Moreover, through internal workshops innovative proposals are developed by the Space Transportation System Analysis team. These proposals intentionally diverge from conventional ideas and concepts. The patented 'in air- capturing' method by which a reusable booster stage is captured by a towing-aircraft is one such example.

SART analyses take place in a frame of national and international cooperation.

Current examples of system analyses carried out at SART are:
