FIELD: car industry.
SUBSTANCE: invention relates to inner case (2) of an intermediate case for a two-circuit gas turbine engine. Outlet (6) contains outlet pipe (18) and one or several outlet ribs that are located in specified pipe (18), while ribs and walls of the pipe form together several straightening channels made with the possibility of removing gas flow (F3) from intermediate space (16), directing it into a flow path of the second circuit flow, while chord length (L2) of at least one of ribs (22) exceeds 50% of length (L1) of pipe channel (18).
EFFECT: invention allows for the reduction in pressure losses and risks of disruption of the second circuit flow in the flow path of the second circuit to increase the performance of the gas turbine engine, and the invention is simple and easy to use and do not lead to an increase in the mass of the gas turbine engine.
