Abstract
Official abstract text for this publication.
A method for deploying a control surface from an exterior surface of a spinning projectile during flight is provided. The method including: moving the control surface in an interior of the projectile such that a portion of the movement retracts the control surface into the interior and a portion of the movement extends the control surface from the exterior surface of the projectile; determining a roll angle of the projectile; and synchronizing the movement of the control surface with the roll angle of the projectile.
First claim
Opening claim text (preview).
What is claimed is: 1 . A control actuation device for a munition, the actuation device comprising: a body having a cavity with an open end exposed to an exterior; a slug/charge stack disposed in the cavity, the slug/charge stack comprising: a first slug retained in the cavity and a corresponding first charge positioned in the cavity such that initiation of the first charge burns propellant contained in the first charge to produce pressure to eject the first slug from the open end to the exterior; and one or more second slugs retained in the cavity and one or more corresponding second charges positioned in the cavity such that initiation of the one or more second charges burns propellant contained in the one or more second charges to produce pressure to eject the one or more second slugs from the open end to the exterior, the one or more second slugs being one or more positioned or sized so as to not interfere with portions of the cavity when being ejected from the open end; and an initiator corresponding to each of the first charge and one or more second charges for selectively initiating the first charge and one or more second charges.
