    • A helicopter having both wing and rotor driven directly by thrust device is provided. The anti-centrifugal turbine engine is mounted on the stud sleeve and secured on the rotor beam. Fuel pipes and controlling lines go through the sleeve and extend to the blade root along the beam. Alternatively, improved gas engine combined with propeller is provided to directly drive the symmetrical rotor with stray bars. The shaft of rotor is provided surrounding the stud sleeve, both of them are fixed about the helicopter center of gravity. The pipes and lines go through the sleeve and extend into fuselage, realizing the function of turning, positioning and propelling cooperated with the power unit under the wing or on the fuselage. A helicopter only having rotor directly driven by thrust device is further provided, wherein the turbine engine or the propeller with gas engine is fixed on the short airfoil provided symmetrically between rotor blades. The rotor and swash plate can cooperate normally or the method of moving the center of gravity can be used to realize the precisely positioning of the light type helicopter in flight. The cost can be reduced.
