TRR 40


Technological Foundations for the Design of Thermally and Mechanically Highly Loaded Components of Future Space Transportation Systems

Rocket Propulsion Systems and their Integration

Next-generation space transportation systems will be based on rocket propulsion systems which deliver the best compromise between development and production cost and performance.

SFB-TR40 focuses on liquid rocket propulsion systems and their integration into the space transportation system.

Atmospheric re-entry of re-usabel space transportation systems will not be investigated in this project - the main focus of research is on specific problems of rocket propulsion systems.

Critical, thermally and mechanically highly loaded components of such space transportation systems are:

  • the combustion chamber
  • the nozzle
  • the aft body and
  • structure cooling.

These components offer the highest potential for an increase in efficiency of the entire system. However, all components are in close and direct interaction with each other. Optimization or even the fundamental new design of a single component directly affects all other components. Therefore, the investigation of individual components separate from the others leads to sub-optimal results.

The scientific focus of all five research areas within the SFB-TRR 40 is the analysis and the modeling of coupled systems. Based on reference experiments detailed numerical models are developed which serve as basis for efficient and reliable predictive simulation tools for design.

Main Objectives in Summary

  • new concepts for rocket nozzles
  • alternative fuels and optimization of the combustion chamber
  • new methods for aft-body flow control
  • innovative cooling methods for propulsion components.
