Claim:
1. An ornithopter engine comprising two moieties, said engine comprises: (a) a structural frame, wherein said structural frame further comprises: (b) driving magnetic members shaft, said driving magnetic members shaft is mounted in said driving magnetic members shaft mounting portion of said structural frame, wherein said driving magnetic members shaft is rotatable relatively to said driving magnetic members shaft mounting portion of said structural frame; (c) at least two driving magnetic members, said driving magnetic members are affixed to said driving magnetic member shaft; (d) at least two swinging members, wherein each one of said at least two swinging members is pivotally mounted onto said swinging member mounting portions of said structural frame, at each one of said moieties of said engine; (e) wherein the at least two swinging members are rotatable relatively to the swinging member mounting portions of said structural frame; wherein each said swinging member comprises at least: (f) at least one driven magnetic member, said driven magnetic member is affixed to said magnetic member associated portion of said swinging member; (g) a motor, rotably coupled to said driving magnetic members shaft; said ornithopter engine is characterized by that: (h) upon rotation of said driving magnetic members shaft, said swinging members perform iterative partial rotation, in opposite directions, in turn, relatively to said swinging member mounting portions of said structural frame; whereby a rotational energy of said driving magnetic members shaft is converted, essentially frictionlessly, into a mechanical energy of a flapping motion, performed by said swinging members.
