SFB TRR 40: Technological Foundations for the Design of Thermally and
Mechanically Highly Loaded Components of Future Space Transportation
Systems
The Institute of Aerodynamics and Fluidmechanics has the
speaker role within the DFG-SFB TRR40. Next-generation
space transportation systems will be based on rocket
propulsion systems which deliver the best compromise
between development and production cost and perfor-
mance. The TRR40 focuses on liquid rocket propulsion
systems and their integration into the space transportation
system.
Critical, thermally and mechanically highly loaded com-
ponents of such space transportation systems are the
combustion chamber, the nozzle, the aft body and the
cooling of the structure. These components offer the
highest potential for an increase in efficiency in the entire
system. However, all components are in close and direct
interaction with each other. Optimization or the fundamen-
tally new design of a single component directly affects all
other components.
The 25 projects from TUM, RWTH Aachen, TU Braun-
schweig and the University of Stuttgart as well as partners
from DLR and AIRBUS D&S investigate in interdisciplinary
experimental and numerical teams. The developed con-
cepts developed will be tested on sub-scale combustion
chambers and will be developed to a stage of applica-
bility. In addition, principal experiments are going to be
conducted to demonstrate new technologies developed
in the TRR40. The scientific focus of all five research
areas within the TRR 40 is the analysis and the modeling
of coupled systems. Based on reference experiments
detailed numerical models are developed which serve as
the basis for efficient and reliable predictive simulation
tools for design.
