摘要： A structure includes a cooled article having an open-cell solid foam of ceramic or metal cell walls with a porous interconnected intracellular volume therebetween. A source of a pressurized gas is in communication with a source region of the cooled article. The source of the pressurized gas includes a gas plenum in gaseous communication with the source region, and a compressor having a compressed gas output in gaseous communication with the gas plenum. Gas flows from the source of the pressurized gas through the porous intracellular volume, to cool the cooled article.

摘要： A propeller with five blades is supported from a hub. A series of apertures is distributed relatively evenly across faces of the blades, the apertures extending from one face of a blade to an opposite face of the blade. The axial extent of the apertures is substantially aligned with the direction of movement of the blades relative to the axis of the propeller. The apertures are normal both to the radial extent of the propeller and the axial extent of the propeller. Each aperture includes a beveled edge in the form of a countersunk lip extending around the periphery on the face. The flow of fluid through the apertures is believed to interfere with turbulent flow such that propeller efficiency is improved.

摘要： An improved watercraft propeller is provided with a hub having a plurality of outwardly extending blades, and at least one reverse thrust member connected to a selected blade of the propeller. The blade to which the reverse thrust member is connected can provide a blade pitch that is constant, variable, progressive, or regressive. The reverse thrust member is formed integrally with or connected to a leading edge of the selected blade. The reverse thrust member effectively increases the pitch of the propeller when operated to propel a watercraft in a reverse direction, thereby improving the performance and efficiency of the propeller.

摘要： A vane structure for a propeller for engaging fluid and preventing cavitation or the rapid formation and collapse of low-pressure gas bubbles in a liquid. The vane structure for a propeller includes a plurality of spaced vanes that are mounted to and extend away from a hub. Each of the vanes has a leading edge, a trailing edge and an end. A lip is mounted on the end of each of the vanes for selectively engaging fluid and dispersing low-pressure gas bubbles positioned generally adjacent to the plurality of spaced vanes.
