<p>A missile or projectile tail section includes an outflow device (20) and a number of deployable fins (26). The outflow device may be a base bleed device that includes a slow-burning propellant which fills the vacuum created by the projectile's motion through the air. Use of the outflow device may allow the projectile range to be extended by up to 20%. The fins are stowed canted relative to planes (41) that include the axis (22) of the tail section. By canting or tilting the fins relative to the axis of the tail section, increased space is made in the tail section for the outflow device. Although the fins are stowed canted relative to the tail section, they may be configured so as to be deployed such that the axis of the tail section is substantially within the planes of the fins.</p> |
