1. An air vehicle (1) comprising:
a body (2),
a cavity (3) located on the body (2),
a rear wall (4) forming a surface on which an airflow (AF) occurring with movement of the body (2) leaves the cavity (3),
a floor (5) over which the airflow (AF) moves along the cavity (3), and
at least one reinforcer (7) having a layer (6) with a curved form in a vertical direction, located on the rear wall (4) and positioned so as to extend into the cavity (3) with an outermost portion of the curved form centered vertically along a height of the rear wall (4), said layer (6) reducing a noise level by decreasing pressure fluctuations caused by unstable air flow (AF);
wherein each reinforcer (7) has an arc shape and is located so as to be mirror-symmetrical with respect to a plane (P) passing through a center of the rear wall (4) at an equal distance to a trailing edge (8), at which the air flow (AF) leaves the cavity (3) and to an intersection edge (9) where the floor (5) and the rear wall (4) intersect.
