Aeroengine propulsion system with dual flux turbo engine and congestion reduction air pre-treatment system

摘要

The invention relates to a propulsion system (120) for an aircraft having an air system.The propulsion system (120) comprises: a nozzle grid (114.114)-A dual flux turbojet engine (110) with a compression stage (202) and a secondary vein (204.0)And - an air sampling system (200) including a heat exchanger (208),Compression stage (202) and air system (206)Through superheater (208)Cold pipe (252) connected to secondary vein (204) and nozzle grid (114.114)Through superheater (208) The air sampling system (200) includes a section (210) arranged at the nozzle grid (114) and moved between an open position (210) n'obtu by an engine (212).Do not restart the nozzle grid hole () and a closed position where window () 210 blocks the nozzle grid hole (114). Position gain can be achieved by integrating exhaust and control functions into the nozzle grid (114).This helps to combine the air sampling system (200) with the propulsion system (120 ℃).
