1. Combustor
Inside the combustor, the compressed air flowing into the chamber is mixed with fuel, where it burns at a temperature of about 1,700 degrees Celsius. New combustor concepts with lean combustion are being developed to reduce nitrogen oxide emissions; they require advanced cooling concepts.
MTU developed a special laser-welding technique for repairing the combustor insert for the T64 engine, which is used, for example, in the Sikorsky CH-53 transport helicopter. This method was then adapted to other engine programs.
