Abstract
A liquid-fueled rocket engine assembly comprises a combustor assembly, a combustor jacket for cooling the combustor assembly using pressurized liquid fuel exiting a fuel pump, a turbine for expanding gaseous fuel exiting the combustor jacket to power the fuel pump and/or an oxidizer pump, a flow control device for directing expanded gaseous fuel exiting the turbine through a first outlet and/or a second outlet, a discharge device for exhausting the expanded gaseous fuel exiting the first outlet, a heat exchanger for cooling the expanded gaseous fuel exiting the second outlet with some of the pressurized liquid fuel exiting the fuel pump, and a mixer for combining cooled fuel exiting the heat exchanger with liquid fuel to form mixed liquid fuel to be directed into the fuel pump. Another liquid-fueled rocket engine assembly and related methods are also described.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
