The annular combustion chamber is located after the compressor within a supporting casing structure. Kerosene is introduced through fuel injectors into the front of this chamber.

This Kerosene is then burnt with air received from the compressor, sending hot gas downstream to the turbine.

• The fuel burns inside the combustion chamber at over 2000°C which about half the temperature of the sun
• The chamber is made from material which has a melting point of just 1300°C
• The Ceramic coating protecting the chamber walls from this temperature is only a quarter of a millimetre thick
