FIELD: mechanical engineering; gas-turbine engine.
SUBSTANCE: cleaning is carried out by delivering cleaning material consisting of solid monodispersed particles into engine passage, using as cleaning material finely dispersed dry ice, snow particles, particles of water ice or frozen snow crust. Cleaning material is fed to engine compressor input at idling or operating speed owing to rarefaction created at compressor input, or cleaning material is fed through nozzle by gas under pressure at repairs. Sodium bicarbonate in amount of 1-5% of ice volume is added to particles of dry or water ice. At temperature within +30 and +40°C particles of water ice are delivered in amount of 1-10% of mass air flow through engine.
EFFECT: reduced contamination of ambient and clogging of turbine blades with hard particles.
