초록 ▼

An apparatus for power production from low velocity fluid flow includes a lateral support arm assembly extending from a vertical drive shaft. A power blade is pivotally secured to the distal end of the support arm, and constrained to pivot within a defined operating angle. The center of force on the power blade is proximal to the power blade pivot, so that at the limit of travel of the support arm the thrust on the power blade moves the power blade into an over-center position, causing the power blade to pivot in retrograde fashion. The pivoted power blade then drives the support arm away from the extreme position, through a neutral position, to the opposite angular position, where the process reiterates and reverses. Thus the lateral support arm is driven continuously in oscillating, lateral motion. An exciter blade joined to the proximal end of the support arm creates a force that augments the torque created by the power blade, and drives the arm past the over-center point of the power blade, causing the power blade to rotate and drive the arm retrograde toward the neutral position. A latch maintains the exciter blade aligned with the arm as it pivots from the neutral (midline) position toward the angular limit of the arm.

A device for producing useful work from a directional fluid flow, including: a drive shaft connected to a machine for producing useful work; a support arm secured to said drive shaft and disposed in said fluid flow, said support arm having a longitudinal axis and a proximal end and a distal end, said fluid flowing past said proximal end toward said distal end of said support arm; a pivot shaft secured in rotatable fashion to said distal end of said support arm; a power blade having a distal portion secured to said pivot shaft and arranged to rotate with said pivot shaft, said power blade disposed obliquely in said fluid flow to create a force in reaction to said fluid flow, said force being generally perpendicular to and spaced apart from said drive shaft to exert torque on said support arm to rotate said support arm about the axis of said drive shaft between angular extremes; means for limiting the range of rotation of said power blade to a first pair of angular excursion limits spaced generally equally from said longitudinal axis of said support arm; said power blade including a proximal edge rotatable about the axis of said pivot shaft between said angular excursion limits to reverse said force and said torque on said support arm and rotate said drive shaft in retrograde fashion in oscillating rotation; means for rotating said power blade toward one of said pair of angular excursion limits as it reaches the other of said angular excursion limits, whereby said oscillating rotation of said drive shaft is sustained indefinitely; and, further including an exciter blade disposed in said fluid flow, and means for securing said exciter blade to said proximal end of said support arm to react to said fluid flow and augment said torque generated by said power blade.
