摘要： An engine comprises an air inlet configured to receive air; a first heat exchanger arrangement arranged downstream of the air inlet, having a first heat exchanger inlet configured to receive at least a portion of the air received by the air inlet, and being configured to cool the air received by the first heat exchanger inlet; one or more turbomachinery components arranged downstream of an outlet of the first heat exchanger arrangement, and being configured to receive air; a first flow path arranged to extend from the air inlet to the first heat exchanger inlet; a second flow path arranged to extend from the air inlet to the one or more turbomachinery components, the second flow path bypassing the first heat exchanger inlet; and a flow control arrangement comprising a first portion and a second portion, the first and second portions being configured to be movable relative to one another to selectively obstruct the second flow path.

摘要： A heat exchanger which may be used in an engine, such as a vehicle engine for an aircraft or orbital launch vehicle. is provided. The heat exchanger may be configured as generally drum-shaped with a multitude of spiral sections, each containing numerous small diameter tubes. The spiral sections may spiral inside one another. The heat exchanger may include a support structure with a plurality of mutually axially spaced hoop supports, and may incorporate an intermediate header. The heat exchanger may incorporate recycling of methanol or other antifreeze used to prevent blocking of the heat exchanger due to frost or ice formation.

摘要： A shell and tube type heat exchanger comprising a shell and a tube arrangement within the shell. The tube arrangement comprises a flow tube. The flow tube furcates at a plurality of nodes along its length. The shell and tube type heat exchanger further comprises a tube matrix fluidly coupled to the flow tube.
