FIELD: aircraft engineering. ^ SUBSTANCE: invention relates to cleaning and prevention of contamination with use of liquid, and it can be used in servicing flying vehicles. Proposed plant contains movable platform of which two tanks are mounted for washing liquid and emulsion with filters connected by pipelines with electrically driven pump, cock, hydraulically driven positive displacement emulsion meter and atomizing device with atomizing nozzles. Cock has four outlets. Inlet of cock is connected through pump with washing liquid tank. First outlet is connected with space of meter hydraulic driven, second one is connected with flexible pipeline to deliver washing liquid to nozzles, third one is connected with mainline to drain washing liquid from atomizing device, and fourth one is connected with mainline to drain liquid from space of hydraulic drive of meter into washing liquid tank. Flexible pipeline delivering washing liquid to nozzles communicates with tank through drain and discharge main line of washing liquid by means channel made in plug of distributing cock. Emulsion space of meter communicates at one side through intake valve with emulsion tank and at other side, through outlet valve, with flexible pipeline delivering emulsion to additional nozzles. ^ EFFECT: simplified design, improved quality of washing and treatment of gas-air duct of gas-turbine engine with emulsion including that with dust trap on air intake nozzle. ^ 13 cl, 14 dwg |
