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.
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.
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.
