Air inlet combining a filter and a bypass device for use with a turbine engine
View Patent ↗An air inlet ( 10 ) for an engine ( 20 ) of an aircraft ( 50 ), the air inlet ( 10 ) having a duct ( 2 ) feeding outside air to said engine ( 20 ) together with a filter system combining at least one filter ( 3 ) and at least one bypass device ( 4 ). Said filter ( 3 ) and said bypass device ( 4 ) are fastened on a common support ( 1 ) situated at one end of said duct ( 2 ) and on a flank of a fuselage ( 51 ) of said aircraft ( 50 ). Said bypass device ( 4 ) comprises a cover ( 5 ) and an actuator ( 6 ) controlling opening of said cover ( 5 ). Thus, when said filter ( 3 ) no longer allows outside air to pass therethrough, said cover ( 5 ) is opened, and outside air passes via the bypass device ( 4 ) in order to feed said engine ( 20 ) with outside air.
1. An air inlet for an engine of an aircraft, the inlet comprising:
a duct for feeding outside air to said engine;
at least one filter and
at least one bypass device allowing said outside air to pass therethrough when said filter is obstructed;
the air inlet being characterized in that said duct, said filter and said bypass device are fastened to a common support, said support being situated at one end of said duct and being fastenable to the aircraft so that the filter and the bypass device can be assembled on the support away from the aircraft.
2. An air inlet according to claim 1 , wherein said bypass device comprises a cover movable relative to said support and at least an actuator for controlling opening of said cover.
3. An air inlet according to claim 2 , wherein said cover pivots under drive from said actuator.
4. An air inlet according to claim 2 , wherein said bypass device includes a gasket providing sealing between said cover in a closed position and said support.
5. An aircraft having at least one engine, said aircraft including at least one air inlet according to claim 1 , each engine being fed with outside air by at least one air inlet.
6. An aircraft according to claim 5 , wherein said aircraft has a fuselage and the support of the air inlet is in a flank of said fuselage.
7. An aircraft according to claim 6 , wherein the filter and the bypass device of the air inlet are flush with said fuselage.
8. An aircraft according to claim 6 , wherein the air inlet comprises a cover movable relative to the support and in that said cover is flush with said fuselage.
