Ducted-fan turbine engine i.e. aircraft turbofan, has slat located in downstream side of discharge passage with respect to flow direction of gas stream, where slat is movable to outlet position in which slat projects inside primary channel

摘要

#CMT# #/CMT# The engine has a low pressure compressor delivering gas stream into a primary channel, and a discharge passage (20) located downstream of the compressor for diverting a part of the gas stream towards a secondary channel. The passage is closed by a slide valve (22). A slat (40) is located in a downstream side of the discharge passage with respect to a flow direction of the gas stream. The slat is movable between a retracted position in which the slat does not project into the primary channel, and an outlet position in which the slat projects inside the primary channel. #CMT#USE : #/CMT# Ducted-fan turbine engine i.e. aircraft turbofan (claimed). #CMT#ADVANTAGE : #/CMT# The arrangement of the slat allows better collection of hail and improved evacuation of the hail, thus preventing the hail from entering into a combustion chamber of the engine, and hence avoiding shut off of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an enlarged sectional view of a mobile slat in retracted position. 8 : Annular duct 20 : Discharge passage 22 : Slide valve 28 : Intermediate shaft 40 : Slat.
