摘要

The aircraft i.e. commercial aircraft, has an engine (6) placed on a rear part (2R) of a fuselage (2) to found coaxial contra-rotating propellers (8, 9) in front of a vertical empennage (5) and a horizontal empennage (4). Non-structural removable noise masking surfaces (14) are formed at the rear part of the fuselage. The surfaces occupy a deployed position in which the surfaces are projected with respect to the rear part of the fuselage and arranged overside of the propellers. The surfaces occupy a retracted position in which the surfaces form a body with the rear part of the fuselage.
