One step slows down, and controls the angle of attack of the horizontal empennage in left and right and afterbody or so the slip-stream of two propellers, produces horizontal backward directions
Lift makes the no longer preceding winged of afterbody high-speed helicopter of verting.Control the slip-stream of two propellers of the horizontal empennage in left and right and afterbody or so
The angle of attack be zero, the lift of left and right transverse direction empennage is zero, and the aerofoil of left and right longitudinal direction empennage is remained perpendicular to horizontal plane, left and right
To being returned to parallel to fuselage vertical line, the slip-stream of afterbody left-and-right spiral oar is flowed through the longitudinal empennage in left and right and produced for the exhibition of longitudinal empennage
With plane-parallel and the lift vertical with fuselage vertical line, by the cunning for changing the longitudinal empennage in left and right and afterbody left-and-right spiral oar
The angle of attack of stream, the lift is manipulated, manipulate direction.
Reduce the rotating speed of left and right main rotor and always away from the lift of two main rotors is less than the weight of body, and vert afterbody height
Fast helicopter vertically declines；Increase the rotating speed of left and right main rotor and always away from the lift of two main rotors is more than the weight of body, inclines
Turn afterbody high-speed helicopter vertical ascent.When the lift of vertical direction is equal to body weight, the afterbody high-speed helicopter that verts hovers.
Realization is excessively vertically moved up or down flight by high-speed horizontal flight.
Because the rotary speed of two main rotors in left and right is slower, blade tip linear velocity is smaller, flies before the level that can be superimposed
Speed is bigger, and the afterbody high-speed helicopter that verts of the invention can use double-deck main rotor structure, i.e. two steering phases of lower floor or so
Anti- main rotor, upper strata or so two turns to opposite main rotor, sets propeller hub to connect flapping hinge, lead lag hinge and oar on main shaft
Leaf, overcome the lift asymmetry of the horizontal forward flight of rotor.To prevent that two layers of blade is interfered because waving up and down, upper and lower two layers
The steering of main rotor is identical, it is necessary to which setting the left side, two layers of main rotor turns clockwise up and down, and two layers of main rotor is counterclockwise up and down on the right
Turn.Vert afterbody structure type it is constant, vert afterbody high-speed helicopter of this high-speed helicopter double-deck left and right main rotor.
