ABSTRACT:
This invention relates to a device to displace fluids or to displace and change the volume and pressure of compressible fluids, comprising a number of vanes radiating from a hinge line or shaft and a governing rotator to change the circumferential spacing of the vanes as they revolve. In various embodiments of the invention the device may be used as a fan or pump, a jet propulsion device for aircraft, a heat pump operating on a pure gas cycle, and as a heat engine with external or internal heat source. In one embodiment of the invention the device may be used to perform the function of the wing of an aircraft, but requiring no horizontal motion of the aircraft itself; however, if this same aircraft is made to move horizontally in a certain direction very high lift coefficients may be obtained.
