  • Device for passive control of the thermal expansion of the extension casing of a turbo-jet engine
    Patent number: 7185499
    Abstract: The invention relates to a device for passive control of the thermal expansion of the extension casing of a turbo-jet engine, said extension casing surrounding the casing of the high pressure compressor of the turbo-jet engine, and including a flange for attachment to an upstream flange of the casing of the combustion chamber. It is characterised in that at least one circumferential cavity is provided between both said flanges wherein circulates a gas flux tapped at the inlet of the combustion chamber. One uses thus a natural circulation generated by the differential pressure. Thanks to the device of the invention, the flange is passively controlled, and the stresses resulting from a differential expansion between the skin of the casing and its attachment flange are reduced.
