Abstract: A regenerative closed loop thermodynamic power generation cycle system is presented. The system includes a high-pressure expander to deliver an exhaust stream. A conduit is fluidly coupled to the high-pressure expander, which is configured to split the exhaust stream from the high-pressure expander into a first exhaust stream and a second exhaust stream. The system further includes a first low-pressure expander and a second low-pressure expander. The first low-pressure expander is coupled to a pressurization device through a turbocompressor shaft, and fluidly coupled to receive the first exhaust stream. The second low-pressure expander is coupled to the high-pressure expander and an electrical generator through a turbogenerator shaft, and fluidly coupled to receive the second exhaust stream. A method for operating the regenerative closed loop thermodynamic power generation cycle system is also presented.

Abstract: A hypersonic aircraft includes one or more leading edge assemblies that are designed to cool the leading edge of certain portions of the hypersonic aircraft that are exposed to high thermal loads, such as extremely high temperatures and/or thermal gradients. Specifically, the leading edge assemblies may include an outer wall tapered to a leading edge or stagnation point. A coolant supply provides a flow of cooling fluid to a porous tip that is joined to the forward end of the outer wall and defines variable porosity and/or internal barriers to direct a flow of cooling fluid to the regions of the leading edge experiencing the highest thermal loading.

Abstract: A method includes directing a refrigerant fluid mixture and a flow of natural gas through a first heat exchanger for exchanging heat between a natural gas flow path and a first refrigerant flow path. The method also includes expanding the flow of natural gas exiting from the first heat exchanger via a first throttle valve. Further, the method also includes directing a generated cold natural gas vapor and a slurry having a liquefied natural gas and solidified carbon dioxide through a filter sub-assembly. Moreover, the method also includes separating the solidified carbon dioxide by the filter sub-assembly to form a purified liquefied natural gas. Finally, the method includes directing a pulse of a cleaning fluid having at least one of methane and carbon dioxide through the filter sub-assembly to remove the solidified carbon dioxide therefrom and storing the purified liquefied natural gas in a storage tank assembly.
