Abstract: An enhanced operating method and an integrated tube-trailers and stationary ground storage system are provided for implementing enhanced pressure consolidation operations for refueling gaseous fuels. The integrated tube-trailers and stationary ground storage system includes gaseous fuel supply tube-trailers and stationary ground storage including at least one or more stationary pressure vessels. A compressor can be supplied by both the stationary ground storage and the tube-trailers. The stationary ground storage can provide higher pressure to the compressor than the tube-trailers, enabling enhanced compressor throughput during refueling operation, and enhanced utilization of tube-trailers payload.

Abstract: The present invention provides a coolant system of a generator arranged to be driven by an aircraft engine. The coolant system comprising a fluid circuit with a fluid therein, the fluid for cooling an electricity generator, and a pump, arranged to provide a flow of fluid around the fluid circuit to deliver coolant to at least one cooled component of the generator, via a cooler. The system also comprises a fluid control device located between the pump and the cooler in the fluid circuit, wherein the fluid control device is configured to selectively direct the fluid provided by the pump away from the cooler in dependence on a measured pressure in the fluid circuit, wherein the measured pressure is derived from a measured point in the fluid circuit, the measured point being remote from the fluid control device.

Abstract: A dependent closed pressure vessel is fluidly coupled to an independent closed pressure vessel. A pressure sensor monitors pressure in the vessels to generate raw pressure measurement data. A flow meter monitors multidirectional rate of flow of fluid between the vessels and the volume of fluid flowing from the independent closed pressure vessel to generate raw rate of flow and raw volume measurement data. A pressure/flow regulator valve adjusts pressure in the dependent closed pressure vessel in response to a pressure set point signal generated in response to the raw pressure data, adjusts the rate of flow of fluid between the vessels in response to a rate of flow set point signal generated in response to the raw rate of flow data, and adjusts the rate of flow of fluid between the vessels in response to a volume set point signal generated in response to the raw volume data.
