Project summary

The project considers:

- Technology of air- barrier complex (ABU);

- Submarine perforated pipeline;

- Release of air jet at subsonic speed;

- Produce of air screen by rising air-bubble jets;

- Interaction with reflecting skimmer wall;

- Produce of strong backward (reverse) flows on the surface, which drives away from intakes attracted substances. This is essential for every kind of intakes and especially for those of

Nuclear Power Plant, Hydro Power Plant and Thermoelectric Power Plant. At the same time the air screen prevents fishes from getting into the pumps and is ecologically effective measure (100% fish protection against getting them into power units); ABU is effective for provision of safe work of the locks of surface outlets as far as entirely excludes possibility of their wedging, because ABU prevents ice-floe from getting into the dam outlet of Hydro Power Plant (HPP) during spring water-flood waves on the river, thus defending dam from destruction, but under the dam excludes destructive consequence of free wave passing.
