FIELD: aviation; helicopter main rotor drives. SUBSTANCE: drive of helicopter main rotor is made in form of gas turbine; it contains hub with blade, common gas duct, spherical gas chamber which is articulated in fuselage; articulated on chamber is tubular axle of rotor hub which is provided with splitter fitted with blades bent in direction opposite to rotation of rotor blade; turbine blades are secured in cavity of rotor blade and blade proper is secured in rotor hub by means of spherical flange - universal joint. Common gas duct is made for delivery of working medium to spherical chamber wherefrom working medium flows to rotor hub through tubular axle and then to turbine blades through universal joints made in form of spherical flanges. Rotation of rotor hub is effected with the aid of bearing fitted with seal. EFFECT: enhanced efficiency. 4 dwgl |
