Abstract: A hypersonic aircraft includes one or more leading edge assemblies that are designed to manage thermal loads experienced at the leading edges during high speed or hypersonic operation. Specifically, the leading edge assemblies may include an outer wall tapered to a leading edge or stagnation point. The outer wall may define a vapor chamber and a capillary structure within the vapor chamber for circulating a working fluid in either liquid or vapor form to cool the leading edge. In addition, a dual-modal cooling structure can enhance heat transfer from the outer wall at the leading edge to the outer wall within the condenser section of the vapor chamber.

Abstract: Heat engines employing fluid bearing assemblies hermetically sealed with a closed flowpath for a working fluid are generally disclosed. For example, the heat engine includes a rotating drivetrain and a fluid bearing assembly. The rotating drivetrain includes a compressor section, an expander section, and a heat exchanger. The compressor section and expander section together define at least in part a closed flowpath for the flow of a working fluid. The heat exchanger is thermally coupled to the closed flowpath for adding heat to the working fluid. The fluid bearing assembly is configured to utilize the working fluid to support the rotating drivetrain. Further, the fluid bearing assembly is hermetically sealed with the closed flowpath.

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.
