A curved body (830), for propelling fluids, crafts and harvesting fluid power, comprises a convex outer leading surface securely connected to a concave inner trailing surface to define an open vessel. Upon oscillation, ambient fluids are accelerated and ejected from the vessel to propel the vessel and the ambient fluids in opposite directions. Apparatus is secured to a motive power source directly or via actuating member (832), by fastening through aperture (834). The oscillating propulsor can be operated directly by a reciprocating motive power source, and indirectly by the reaction momentum imparted to a supporting base. Thrust may be vectored by rotation of the curved body (830) about the supporting base. Drag reduction using fluid dynamic shapes, intake openings, a fore fin (844), an aft fin (846), and a lubricant cavity, are embodied. Enhanced propulsion using multistage oscillating propulsors is embodied.
