FIELD: jet engine engineering. ^ SUBSTANCE: engine comprises intermediate frame casing interposed between the primary and secondary loops and mounted between the low-pressure compressor and high pressure compressor, relief means that are directed a part of the air flow generated by the low-pressure compressor to the secondary contour. The intermediate casing has a number of cantilevers with areas arranged over its periphery. The relief means are provided with means for sucking air in the primary loop and mounted at the entrance to intermediate casing and means for removing the air to the secondary loop downstream of cantilevers. The means are provided with passages arranged around the intermediate casing under the areas. ^ EFFECT: simplified structure . ^ 1 dwg |
