摘要： A fuel tank inerting system for an aircraft, the system comprising: a fuel tank, and a catalytic heat exchanger. The catalytic heat exchanger comprises a first flow path and a second flow path for heat exchange with the first flow path, as well as a first inlet arranged upstream of the first flow path of the catalytic heat exchanger for providing a mixture of fuel vapour and oxygen to the first flow path for sustaining a catalysed reaction, and a second inlet arranged upstream of the second flow path for providing a flow of fuel from the fuel tank to the second flow path of the catalytic heat exchanger for exchanging heat with the first flow path. The system further comprises a transfer pipe in heat exchange with the fuel tank, wherein the transfer pipe is arranged to receive fuel from the second flow path of the catalytic heat exchanger.

摘要： A device for evaporating a liquid such as liquid fuel. The device comprises: a shell; means for supplying heat to the shell; a porous wick located in the shell so that there is a gap between an outer surface side of the porous wick and an inner surface of the shell; means for supplying liquid to the porous wick; and an outlet in the shell for vapour produced in the gap by the application of heat from the shell to the liquid in the wick.

摘要： The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

摘要： A counterflow heat transfer system comprises a heat exchanger and a flow controller arranged to convey a first fluid through the heat exchanger in a first flow direction and a second fluid through the heat exchanger in a second counterflow direction. The heat exchanger comprises at least one first thermally conductive tube conveying the first fluid and at least one second thermally conductive tube conveying the second fluid. The first and second tubes are wound around one another and in contact with one another in an entwined tubular arrangement.
