ABSTRACT:
The present invention relates to a ground test installation for the jet engines (5A, 5B) of an airliner (2) equipped with at least two jet engines linked to the wings of the aircraft, comprising, for each jet engine (5A, 5B), a silencer (8A, 8B) having a body of generally cylindrical elongate shape, said silencers being intended to each be arranged behind the nozzle of one of said jet engines. According to the invention, this installation comprises a casing (6) which is acoustically insulating and permeable to air, intended to envelop at least the front part of the fuselage (3) and the wings (4A, 4B) of the aircraft (2), and the rear wall of which (7A, 7B) is connected to the front end part of each of said silencers (8A, 8B).
