Projectile fin deployment mechanism has fin support that pivots about axis perpendicular to lengthwise axis of projectile

摘要

A mechanism (2) for deploying the fin of a projectile (1) between launch and trajectory positions comprises a fin support (5) that pivots about an axis (7) perpendicular to the lengthwise axis (4) of the projectile. The fin is connected to the support by a rod (8) that lies parallel to the projectile's axis in the launch position and perpendicular to it when deployed. The rod can also be made to rotate relative to the support as it is deployed, with the rotation controlled by a drive, and it can be moved lengthwise by a head (9) interacting with a cam surface (14).
