Thermal analysis and design

Thermal control of space products is an extreme challenge. Our experience in multiple space programs helps you find a design that works.
We work according to stringent requirements of european space standards ECSS-E-ST-31C, ECSS-E-HB-31-01 and ECSS-E-HB-31-03A. For thermal analysis we use state-of-the-art software suites such as ESATAN-TMS®, THERMICA® und Thermal Desktop®.

Thermal modelling and analysis

  • Modelling based on CAD design data (GMM)
  • Problem-adapted discretisation
  • Consideration of all relevant boundary conditions (radiative, conductive - TMM)
  • Consideration of thermo-optical properties (TMM), beginning of life / end of life
  • Steady state heat flow analysis
  • Transient heat flow analysis
  • Definition of required radiator areas
  • Definition of required heater power and locations
  • Efficient analysis of all possible orbits and spacecraft configurations

Thermal design

  • Selection of appropriate thermal control hardware items:
  • Radiators
  • Heatpipes
  • MLI
  • Heaters
  • Heat straps
  • Thermal interface filler (e.g. Sigraflex®)
  • Surface coatings (OSR, black/white paint, etc.)
  • Optimisation of thermal control systems
