    摘要: The present invention provides heat exchanging elements for use in Stirling engines. According to the present invention, the heat exchanging elements are made from muliple platelets that are stacked and joined together. The use of platelets to make heat exchanging elements permits Stirling engines to run more effiecient because the heat transfer and combustion processes are improved. In one embodiment, multi-stage combustion can be introduced with platlets, along with the flexibility to use different types of fuels. In another embodiment, a single component constructed from platelets can provide the heat transfer rquirements betweeen the combustion gas/working gas, working gas in the regenerator and the working gas/coolant fluid of a Stirling engine. In another embodiment, the platelet heat exchanging element can recieve solar energy to heat the Stirling engine's working gas. Also, this invention provides a heat exchanging method that allows for multiple fuilds to flow in opposing or same direction.

    摘要: A throttling injector is constructed with a swirl chamber, a plurality of tangentially directed liquid fuel inlets and an outlet orifice, the inlets arranged to create a swirling flow in the swirl chamber to leave through the outlet in a stream that is in the shape of a hollow tube or cone. Variations in the number of inlets that are actuated results in variations in the thickness of the wall of liquid in the tube or cone and hence variations in the volumetric flow rate of fuel ejected from the outlet orifice without changing the linear velocity of the fuel in the axial direction through the orifice or the pressure drop across the orifice. The injector thus permits throttling to occur from a high to a low volumetric fuel flow rate without the chugging instability that plagues liquid-fuel-fed combustion chambers of the prior art.

    摘要: A combustion chamber/supersonic nozzle assembly is cooled by an array of coolant channels in the wall of the assembly with coolant being fed to the assembly at the throat plane between the subsonic (convergent) and supersonic (divergent) sections. A minor portion of the coolant entering at the throat plane is directed to coolant channels in the supersonic section wall, while the remainder is directed to a complex arrangement of channels in the subsonic section wall. The latter arrangement includes an outer layer of wide axially oriented channels for delivery of coolant to, and removal from, an inner layer of smaller, circumferentially oriented channels that are adjacent to the hot gas and carry the bulk of the coolant load. The path of coolant travel through each inner channel is relatively short, lessening the pressure drop through those channels relative to coolant channel arrangements of the prior art.
