Claim:
A helicopter that can directly propel rotors into the hovering state, comprising: a fuselage ( 13 ) having a center of gravity; a rotor ( 5 ) with a pull rod and a jackstay ( 2 ); a turbine ( 1 ) comprising a plurality of propellers; a pair of wings ( 14 ); a hollow short shaft ( 37 ); a hollow short dead axle ( 36 ) with a bearing and a base ( 7 ), said base having an underside; a plurality of throttle lines ( 35 ); a plurality of wires ( 34 ); a first fuel delivery pipe ( 30 ); a hydraulic system; an axle sleeve ( 4 ); and a root axle ( 3 ); wherein the turbine ( 1 ) directly drives the rotor ( 5 ); the turbine ( 1 ) is installed on the hollow short shaft ( 37 ); the hollow short shaft ( 37 ) is installed inside the hollow short dead axle ( 36 ); the hollow short dead axle ( 36 ) is fixed on the rotor adjacent to a root of the rotor ( 5 ); the hydraulic system controls a propelling direction of the turbine; the throttle lines ( 35 ), the wires ( 34 ) and the first fuel delivery pipe ( 30 ) pass through the hollow short shaft ( 37 ) and are received in a crossbeam of the rotor; the axle sleeve ( 4 ) of the rotor is installed on the hollow dead axle ( 36 ), and hinged with the root axle ( 3 ) and the pull rod and the jackstay ( 2 ); the base ( 7 ) is offset from the gravity center of the fuselage ( 13 ); a plurality of pipelines is offset from the base and connected with a control system; and steering, outward pushing, positioning and propelling control is provided by a single drive under the plane defined by both wings ( 14 ) or by a single drive under the fuselage ( 13 ).
