Title:
RECIPROCATING LIFT AND THRUST SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2019/190731
Kind Code:
A3
Abstract:
A reciprocating lift and thrust system includes at least an airfoil and a reciprocating driver configured to produce a reciprocating motion of the airfoil. The system may further include a control unit to change or maintain a suitable angle of attack of the airfoil for lift or thrust as well as to facilitate the cyclic control of the flying vehicle driven by the reciprocating system. The lift and thrust system may be deployed in module that includes at least two airfoils and is configured to substantially cancel out the inertia forces and moments associated with the individual airfoils. The reciprocating driver may be, but not limited to, a mechanical, an electromagnetic, an electrical, or a hydraulic driver. The embodiments of the subject invention provide novel and advantageous reciprocating lift or thrust system for aircraft, flying motor vehicles, or watercraft.
