The wing movement has a gearbox, a reference gear extending through the gearbox and being movably mounted to the gearbox, an input shaft extending through the reference gear and into the gearbox and first and second output shafts movably extending from the gearbox at right angles with the input shaft. There is also provided a motor having a drive shaft connected to the input shaft of the gearbox for rotation of the input shaft. A bracket is connected to the motor base and to the reference gear for retaining the reference gear to the motor base, with an axis of the reference gear in alignment with the drive shaft of the motor. A gearing system is mounted inside the gearbox for rotating the first and second output shafts one full turn in opposite directions relative to each other, upon a rotation of the input shaft one full turn, and for rotating the gearbox one full turn about the reference gear upon a rotation of the first and second output shafts one full turn. A pair of wings is mounted to the output shafts and are movable along a curved infinity-symbol-like pattern projecting substantially along one side of the motor.

[ We claim:] [5.]5. An ornithopter propelling arrangement comprising a first and second wing movements and a frame extending between said first and second wing movements and holding said first and second wing movements in a spaced-apart relationship; said first wing movement comprising:first and second perpendicular axes, said second axis intersecting said first axis at a mid point of said first axis;means for retaining said second axis to said frame;a pair of first wings mounted on said first axis, one of said first wings being on each side of said second axis;means for rotating said first wings in opposite directions relative to each other about said first axis;means for rotating said first axis and said first wings about said second axis in a first rotational mode; andmeans for synchronising a rotation of said first wings about said first axis, with a rotation of said first axis and said first wings about said second axis;said second wing movement comprising:third and fourth perpendicular axes, said fourth axis intersecting said third axis at a mid point of said third axis;means for retaining said fourth axis to said frame;a pair of spaced apart second wings mounted on said third axis, one of said second wings being on each side of said fourth axis;means for rotating said second wings in opposite directions relative to each other about said third axis;means for rotating said third axis and said second wings about said fourth axis in a second rotational mode, opposite said first rotational mode; andmeans for synchronising a rotation of said second wings about said third axis, with a rotation of said third axis and said second wings about said fourth axis;such that said first wings are movable to define a first curved infinity-symbol-like pattern projecting substantially along one side of said frame, and said second wings are movable to define a second infinity-symbol-like pattern projecting along a second side of said frame.
