FIELD: transport.
SUBSTANCE: invention relates to aircraft with systems of fluid flow ducts for suction out of laminar layer and/or blowing in fluid medium in vulnerable zones of outer skin. Proposed system is connected via controlled valve to pump unit and drive by airflow ejected from aircraft cab to create necessary rarefaction for laminar air suction out. To create increased suction-out pressure, said system is connected via controlled vales to lines of compressed air forced from aircraft and/or additional compressor unit. System incorporates control unit to transmit control signals via control lines to control valves depending upon input parametres, e.g. flight parameters, cab pressure, ambient temperature and pressure and engine operating conditions.
EFFECT: reduced power consumption in sucking out laminar flow.
