A panel (3) for controlling the aerodynamic phenomena generated by a body (0) to be positioned on a surface of an aircraft (V). The panel (3) can be associated with the base of the body (0) and includes at least one inlet aperture (322) and at least one outlet aperture (322′) placed in communication with each other, through which a portion of a fluid flow (W) in which the body (0) is immersed can selectively pass. The inlet aperture (322) is located upstream of the body (0) and the outlet aperture (322′) is located downstream of the body (0), with respect to the direction of the fluid flow (W).

1. A panel associated with a body for controlling aerodynamic phenomena generated by the body with which the aerodynamic phenomena is associated; said body is suitable to be positioned on a surface of an aircraft; said body having a longitudinal extension normal to the surface of the aircraft; a fluid flow acts upon said body, thereby generating undesired aerodynamic phenomena;the panel is distinct from said body and assembled at a base of said body positioned in correspondence to a portion of the body which is in contact with the surface of the aircraft;the panel comprises an integrally formed inlet aperture and an integrally formed outlet aperture, and the panel defines a cavity; said cavity is in communication both with said inlet aperture and with said outlet aperture, defining a path where a portion of the flow can selectively pass;said inlet aperture, which selectively allows a portion of the fluid flow to enter the panel, is located upstream of said body with respect to a direction of the fluid flow, and said outlet aperture, from which an output fluid flow exits the panel, is located downstream of said body, with respect to the direction of the fluid flow;said outlet aperture is shaped to generate an output fluid flow which is substantially perpendicular to the direction of the fluid flow acting upon said body, interfering with the aerodynamic phenomena generated by the body;said body is an aerodynamic protuberance comprising a sensor, a probe, an antenna, an air data sensor or an integrated multi-function probe, and said body comprises a region with at least one profile having a circular or semicircular or elliptical section. 2. The panel according to claim 1, wherein said outlet aperture is shaped to generate an output fluid flow which is substantially perpendicular and the panel comprises only one cavity. 3. The panel according to claim 1, wherein said body comprises in an interior, electronic measurement and communication devices suitable to be electrically connected to the aircraft. 4. The panel according to claim 1, wherein said cavity is toroidal and surrounds the body. 5. The panel according to claim 1, wherein said inlet aperture and said outlet aperture comprise a plurality of through holes. 6. The panel according to claim 5, wherein said cavity is defined by a face-sheet, comprising said plurality of holes, and a back-sheet, defining the base of the panel. 7. The panel according to claim 4, wherein said panel has an average porosity in the range of 5 to 20%. 8. A method for controlling aerodynamic phenomena generated by a body positioned on a surface of an aircraft and immersed in a fluid flow; the method comprises the following steps: providing a panel comprising an integrally formed inlet aperture and an integrally formed outlet aperture, the panel defining a cavity; said cavity is in communication both with said inlet aperture and with said outlet aperture, defining a path where a portion of the flow can selectively pass; the panel is distinct from said body and assembled at a base of said body positioned in correspondence to a portion of the body which is in contact with the surface of the aircraft;detecting arising of an aerodynamic phenomenon generated by the body, whether actively or passively;channelling a portion of the fluid flow in which said body is immersed upstream of the body with respect to a direction of the fluid flow and into the inlet aperture of the panel;directing the channelled fluid through the cavity and out the outlet aperture of the panel downstream of said body, with respect to the direction of the fluid flow, thereby generating an output fluid flow interfering with the fluid flow;said output flow is substantially perpendicular to the fluid flow. 9. An aircraft comprising a surface comprising an assembly comprising a panel and a body according to claim 1. 10. The aircraft according to claim 9, in which said panel is integrated into the surface of the aircraft whereon the body is positioned. 11. The aircraft according to claim 9, in which said panel is secured to the aircraft by a fastener. 12. The panel according to claim 1, wherein said body is adapted to rotate about a longitudinal axis of said body, the longitudinal axis being coaxial with a normal to the surface of the aircraft on which the body is positioned, said panel remaining stationary with respect to the surface of the aircraft on which the body is positioned while the body rotates.
