摘要:
A method for operating a gas turbine engine including a first compressor, a second compressor, a combustor and a turbine, coupled together in serial flow arrangement. The method includes channeling compressed airflow discharged from the first compressor to a heat exchanger having an airstream flowing therethrough, channeling an evaporatively cooled airstream into the heat exchanger to facilitate reducing an operating temperature of the heat exchanger, and extracting energy from the compressed airflow using the heat exchanger airstream to facilitate reducing a temperature of the compressed airflow and channeling the compressed airflow from the heat exchanger to the second compressor

A cryogenic fuel storage system for an aircraft is disclosed including a cryogenic fuel tank having a first wall forming a storage volume capable of storing a cryogenic liquid fuel; an inflow system capable of flowing the cryogenic liquid fuel into the storage volume; an outflow system adapted to deliver the cryogenic liquid fuel from the cryogenic fuel storage system; and a vent system capable of removing at least a portion of a gaseous fuel formed from the cryogenic liquid fuel in the storage volume.
摘要:
An apparatus and method for dynamic allocation of multiple processor cores in a computer running an operating system includes providing a program operable to halt a core from processing instructions from a respective ready queue. A next step includes establishing a maximum count of tokens available to allow the program execution, wherein the maximum count is less than a total number of cores. A next step includes obtaining tokens by the cores, wherein at least one core will not be able to obtain a token. If a token has been obtained by a core, executing the program by that core, or otherwise not executing the program by that core and remaining active to process instructions from the respective ready queue of that core.
