SYSTEM FOR OPERATING HELICOPTER BLADES WITH COMPRESSED AIR

摘要

A system for operating helicopter blades with compressed air includes at least a first machine having an engine and configured for generating mechanical power to lift the helicopter; at least a second machine having a compressor and configured for generating compressed air for operating the hollow blades, the first machine being coupled with the second machine; and a rotor having a hollow shaft and an oscillating hollow head supporting the blades. The hollow shaft of the rotor internally including a conduit connecting the hollow shaft of the rotor to the hollow head. The oscillating hollow head is an elastic head and comprises an elastomeric flexible and deformable channel connecting the conduit with the blades and having a shape as at least one “V” and a number of branches equal to the number of the blades, the branches being able to guide the compressed air towards nozzles of the blades.
