TURBOMOTEUR COMPRISING TWO DISTINCT VENTILATION FLOWS

摘要

The invention proposes a turbine engine with unducted propellers comprising a gas generator and a thruster with counter-rotating propellers which is separated from the gas generator by an intermediate casing (40), the turbine engine comprising a casing (100) and a radially inner shell ( 44), which are connected by hollow radial arms (50), said casing (100) also partially delimiting a flow vein (48) of a secondary gas stream, wherein each radial arm (50) is hollow and is crossed by at least one servitude (54) of the turbine engine, characterized in that at least one arm (50) is traversed by a duct (56) for circulation of ventilation gas from the secondary gas flow and which opens into direction of at least one component among in particular a power turbine and a mechanical transmission of said thruster.
