Abstract
A method for cleaning a jet engine includes introducing into the engine, via a carrier gas by way of at least one nozzle, a cleaning medium which contains solids. The pressure of the carrier gas is 1 to 5 bar. An exit of the at least one nozzle is disposed at a radial spacing from a rotation axis of the engine which corresponds to 0.6 to 1.2 times the radius of the entry opening of a first compressor stage that is directed upstream. A main exit direction of the nozzle in relation to the rotation axis of the engine encloses an angle of 10 to 30°.
