TURBOREACTOR WITH PROTECTIVE MEANS FOR A FUEL INJECTION DEVICE, INJECTION DEVICE AND PROTECTIVE COVER FOR THE TURBOJET ENGINE

摘要

The turbojet engine of the invention comprises one or more compressor stages, a combustion chamber, one or more turbine stages, a primary gas flow heating channel and an exhaust nozzle, the heating channel comprising at least one fuel injection device (8) in the primary gas flow, which comprises an open enclosure, comprising at least one wall (8 ') and within which fuel injection means extend ( 8b), which inject the fuel (10) in at least one direction. It is characterized in that the fuel injection device (8) comprises protective means (8d) interposed between the fuel injection means (8b) and the wall (8 '), in a direction of fuel injection (10) .Thus, thanks to the invention, the fuel injection device (8), bathed in a very hot environment, is protected against thermal shocks due to the projection of fuel (10) colder on its walls and its life is increased. / P
