FIELD: engines and pumps.
SUBSTANCE: proposed noise killer comprises walls to shape air intake that are, at least, partially formed by noise killers designed to muffle sound frequencies generated by compressor. Gas turbine engine comprises compressor and channel to feed air thereto with open front end outer opening defined by engine metal housing. Air intake walls are made up of annular parts with inner and outer ends. Inner ends of said annular parts are jointed to metal housing along channel outer opening. Another invention of the set relates to helicopter gas turbine engine equipped with said noise killer.
EFFECT: efficient noise killer.
