Abstract
A shut-off system for an orifice of a duct, particularly for an orifice of an air inlet passage that allows air into the combustion chamber of a ramjet, includes a shutter for shutting off the orifice of the duct, and a controllable actuating device capable of acting on the shutter to uncover the orifice. The shutter includes a removable cap which is held on the duct and a locking device which keeps the cap on the duct by at least one locked jaw, which is unlockable. The actuating device includes at least one controllable striker which is capable of unlocking the jaw in such a way as to cause the cap to be ejected from the duct and to uncover the orifice.
