NACELLE OF JET TURBINE ENGINE, WHICH IS EQUIPPED WITH REDUCTION DEVICES OF NOISE CREATED WITH SUCH ENGINE Russian patent published in 2012 - IPC F02K1/46 

FIELD: engines and pumps.

SUBSTANCE: nacelle of jet turbine engine includes rear internal and external elements. Rear external element includes distributing contour going outwards at the outlet of jet turbine engine and having the possibility of being connected to supply source of noise reducing fluid medium, which is located before rear external element. Rear external element is provided with thrust reverser having the possibility of being changed over from closed position to open position. Distributing contour includes at least one supply pipe providing the fluid medium transfer from supply source to outlet of jet turbine engine. Supply pipe either includes extension-type tubes providing alternating change-over of thrust reverser from closed position to open position, or its front end is equipped with coordination devices providing the appropriate contact with interface zone connected to supply source directly or indirectly. The other invention of the group refers to the plant containing the above nacelle including fluid medium supply source connected to each supply pipe. One more invention refers to the aircraft containing the above plant; at that, according to the first version, jet turbine engine is used in it as supply source, and according to the other invention, supply source is located aboard the above aircraft.

EFFECT: inventions allow installation of noise reduction device emitting the noise reducing fluid medium on the nacelle with thrust reverser.
