Aircraft cover including means for limiting the scoop phenomena of pneumatic type

An aircraft nacelle (10) having an outside wall with a cowl (14) that moves relative to the rest of the nacelle (10) in such a way as to block or unblock an opening, said cowl (14) comprising:

• an articulation (15) relative to the rest of the nacelle (10) and a latch (17) opposite the articulation for holding said cowl (14);
• and
• means (19) for limiting the appearance of scooping phenomena, said means (19) for limiting the appearance of the scooping phenomenon comprising at least one lock (26) that is integral with the rest of the nacelle (10) or respectively the cowl (14) and that occupies a locked state in which a part of the lock (26) interferes with the cowl (14) or respectively the rest of the nacelle (10) and prevents a deformation that comprises a radial component of said cowl (14) and a free state in which said part of the lock (26) no longer interferes with the cowl (14) or respectively the rest of the nacelle (10) and allows the opening movement of said cowl (14),
• wherein the at least one lock comprises a membrane arranged to receive a gas so as to switch the at least one lock between the locked and free states by a pressure variation of the gas.
