ASSEMBLY OF TANDEM FLAPPING WINGS WITH AUTOMATIC CYCLIC TWIST AND ROLL CONTROL Russian patent published in 2009 - IPC B64C33/00 B64C33/02 A63H27/18 

FIELD: transport.

SUBSTANCE: proposed assembly of flying vehicle tandem driven wings flapping towards each other incorporates twistable wings (1) and crank-and-rocker anti-phase-coupled mechanisms (2). Note that, spars or wing strong edges make bell-cranks-rockers of the aforesaid mechanisms. Three-hinge con rods (4) of the said mechanisms impart to the spars or wing strong edges (5) both flapping, the main, motion and automatic wing twisting during flapping. Note that the wings reciprocate along the flapping axis independently of flapping, that causes turning of the three-hinge con rods about crank pins and, respectively, the wings misalignment, independent of flapping or gliding, relative to inclined axles of con rod upper hinges which allows the roll control.

EFFECT: improved flow about flapping wing, flapping wing roll control.
