Research Field: Electric Propulsion and Plasma Wind Tunnel Technology

Development of plasmadynamic rocket thrusters of all performance leves between o.5 kW and 1 MW. Ample numerical codes are plotted, arcjet instabilities are investigated and cathode erosion mechanisms are researched for the construction of these arcjet thrusters. Preparation of the arcjet thrusters' flight mission. (ATOS on a P3D satellite / with Ariane 502)
In five plasma wind tunnels, all equipped with thermal and magnetoplasmadynamic sources, the thermal conditions during the reentry of a space craft into the Earth's atmosphere or into the atmosphere of other celestial bodies can be simulated. The catalytic investigations of thermal protection materials can be carried out in the inductively heated plasma wind tunnel PWK3 . Development and qualification of measuring devices for space gliders and return capsules.

Theoretical, numerical model construction of the plasma wind tunnel simulation for the development of new diagnostic and calculation procedures.

Development of plasma sources for material processing and chemical process control.

Unique experimental facility consisting of a vacuum plant with a suction capacity of 200 000 m3/h at 1 Pa and a 6 MW high current unit allowing space flight simulation tests and experiments on electrothermal und magnetoplasmadynamic thrusters.
For complicated numerical simulations a network workplace computer system as well as a high performance computer are available for use.

Research field:Mission and System Analysis

The development of numerical simulation, analysis and optimization procedures for flight guidance, flight performance prediction and construction of future reusable space transportaion systems with rocket and air breathing propulsion. In order to determine unique mission requirements of various carrier and orbital systems and reentry and return flight crafts in draft drawings, the interaction between system traits, flight path, flight load and capacity are researched. The thermal behavior of the MIRKA thermal protection system and the draft of a semiballistic return capsule COLIBRI are being investigated for the DARA return projects MIRKA and COLIBRI.

Research field: Space Flight Utilization and Aerothermodynamics

System studies on concept, design, development and operation of space stations and platforms, and on subsystems and live load elements and their accomodation. Development of technology experiments and telescience operation for the International Space Station. Safety studies for manned space flight systems. Numerical aerothermodynamic reentry simulation of space crafts: URANUS Navier-Stokes procedure for high temperature, unbalanced flows, adaptive direct simulation Monte Carlo procedure LAS VEGAS for thinned reacting flows, HERTA Monte Carlo simulation procedure for spectral dissolved radiation transport processes in reabsorbant gases. MIRKA/COLIBRI aerothermodynamic.
