Xa=R1*cos (T)+R2*sin (T/2),

Ya=R1*sin (T)-R2*cos (T/2),

T=0 ~ 720 degree；

The plane coordinate value of b points is Xb, Yb, and its curvilinear equation is：

Xb=R1*cos (T)-R2*sin (T/2),

Yb=R1*sin (T)+R2*cos (T/2),

T=0 ~ 720 degree；

It is relative, when C points rotate around O points and a points and b points move along curve 12, a points and b points around C points rotating speed with C points around O The ratio between rotating speed of point is 1：2.

Further, in order to improve the stationarity that the same ambulatory claw moves along the synchronous guide track, can use in two The symmetrical 720 degree of hypocycloids superposition of the heart.

Further, the synchronous guide track can also use magnetic track, to reduce friction, reduce noise；It is described synchronously to lead The effect of rail is to constrain or guides the movement locus of the same ambulatory claw；In addition, the adoptable guide rail structure of prior art It is numerous, do not enumerate.

Beneficial effect

The invention provides a kind of rudder wing helicopter promoted by cross flow fan, has fixed wing aircraft speed of a ship or plane height concurrently and helicopter can The advantages of VTOL, the prototype of unmanned plane can be included as a variety of dual-use helicopters.
