FIELD: transportation; aviation.
SUBSTANCE: method includes erection of an air tunnel, air superchargers and a power drive of superchargers. A power drive is made in the form of hydraulic units-generators of pneumatic energy that directly transform energy of water flow into energy of compressed air. Hydraulic units are placed into a stream bed in parallel to the speed of water motion. Pneumatic energy received by hydraulic units is accumulated in pneumatic accumulators, from where the air stream is sent into expanders and then to an air tunnel.
EFFECT: possibility to use energy for tunnel operation produced from renewable sources of energy, natural low-head streams.
