6/9/2015· In non-afterburning engines the exit temperature inside the nozzle is around 600°C at full continuous thrust. If the aient temperature is low, less heating is needed for the same thrust, and exit temperatures are lower. The maximum temperature for a given engine is, however, independent of altitude and given by the materials inside the engine.
