System (20) for operating the helicopter (1) blades with compressed air, comprising: - at least a first machine comprising an engine (5) and configured for generating the mechanical power necessary to the helicopter lift; - at least a second machine comprising a compressor (8) and configured for generating the compressed air for operating the hollow blades (2); - coupling means for coupling the first machine with the second machine; and - coupling means for coupling the second machine with the blades (2) comprising a hollow shaft of the rotor (3) and a hollow elastic head (13) of the rotor (3) supporting the blades (2), the hollow shaft of the rotor (3) internally comprising a conduit (9) connecting the hollow shaft of the rotor (3) to the hollow elastic head (13). The system (20) further comprises an elastomeric flexible and deformable channel (15) connecting the conduit (9) of the hollow shaft of the rotor (3) with the blades (2) and having a shape as a multiple "V" which present at the end portions a number of branches equal to the number of the blades (2) able to guide the compressed air towards nozzles (4) of the blades (2). |
