limit aero-thermal heat flux


maximum or minimum local heat flux values, or the most unfavourable simultaneous combination of the constituting terms (in the sense of maximizing- or minimizing these heat fluxes) liable to be attained in the different areas of the vehicle during the normal service life for the corresponding mission instant


  • NOTE 1 Limit aero-thermal heat flux applies to TPS and hot structures only.
  • NOTE 2 Aero-thermal fluxes can be caused by molecular flow and can also act after fairing jettisoning or at very low attitudes at orbital velocities.
