Abstract
A cover (1) for protecting the surface (23) of a lens (3) disposed at the rear surface (21) of a guided projectile (7) is fabricated of Teflon or other soft material. Lens (3) faces rearward to receive guidance signals used to keep projectile (7) on a chosen path. Cover (1) protects lens surface (23) from combustive gases and particulates generated during projectile (7) firing, but must be removed shortly after firing to permit lens (3) to receive its guidance signals. Cover (1) comprises at least one vacated chamber (15) for receiving, via holes (17), high pressure combustive gases during firing. Subsequent to firing, the greater pressure within chamber (15) compared with the pressure surrounding cover (1) produces a net force of removal between cover (1) and projectile (7), causing cover (1) to be removed therefrom as desired.
