초록

The invention relates to equipment for the air intake of an aircraft turbine engine, which equipment includes an inlet duct capable of being obturated by a bullet therein, and a bullet thrust mechanism connected to the duct by studs forming bullet guides. Part of the duct is formed by box members for receiving a plurality of separating elements downstream of deflectors, the internal face of the duct lip together with the external face of the bullet and of a jack piston and cylinder of said thrust mechanism being made of soundproofing material.
