    摘要: The invention relates to a turbomachine comprising an air compression stage (2) comprising at least one moving compressor wheel (20), an air intake pipe (4) coupled to said air compression stage (2), a first sealing device (54) positioned between a front portion (56) of the moving compressor wheel (20) and the air intake pipe (4) comprising at least one pressure seal (60), a channel (45) for conveying air compressed by the moving wheel (20) and a second sealing device (64) positioned between a rear portion (66) of the moving compressor wheel (20) and the conveyance channel (45) and configured to receive an air flow (F2) coming from the conveyance channel (45), the turbomachine being remarkable in that the second sealing device (64) is configured to allow a withdrawal (F3) of part of the air passing through it and in that the withdrawn air (F3) is conveyed to the pressure seal (60) of the first sealing device (54) so as to keep it pressurized.

    摘要: A gas turbine engine (121) comprises a main compressor section having a high pressure compressor (141) with a downstream most end (140), and more upstream locations (126). A turbine section has a high pressure turbine (144). A first tap taps air from at least one of the more upstream locations (126) in the main compressor section, passes the tapped air through a heat exchanger (122) and then to a cooling compressor (124). The cooling compressor (124) compresses air downstream of the heat exchanger (122). A second tap taps air from a location closer to the downstream most end (140) than the location(s) (126) of the first tap. The first and second tap mix together and are delivered into the high pressure turbine (144). An intercooling system for a gas turbine engine (121) is also disclosed.
