Raw is positive incidence, and lift direction is upper left side；Blade is in left and does not generate lift since paddle speed is parallel with string；
Blade movement is in lower left, pushes the manipulation pull rod of blade so that blade generates positive incidence, lift direction with linear velocity direction
For upper right side；Blade is below, and pushes the manipulation pull rod of blade so that blade generates positive incidence with linear velocity direction, rises
Force direction is surface, and blade is in lower right, and pull rod is manipulated by control, and blade is made to generate positive incidence, and lift direction is a left side
Top；Blade is in right, by manipulating the control of pull rod, keeps paddle speed parallel with string, does not generate lift；At blade
In upper right side, by manipulating the control of pull rod, blade comes back, and lift is upper right side.It is circumferentially generated from there through analysis blade
Lift situation can obtain, when blade is in the left and right, lift will not be generated；And when blade is in other orientation
When, so that it may to generate the lift component of surface.So when rotating disk is displaced to below cycloid propeller rotary shaft, pass through cycloid propeller
Movement, blade will generate direction be surface resultant force.
There are many utility model concrete application approach, and the above is only the preferred embodiment of the utility model, should
It points out, for those skilled in the art, without departing from the principle of this utility model, can also make
Go out several improvement, these improvement also should be regarded as the scope of protection of the utility model.
