Abstract

The KB-27A gun camera developed for the F-15 employs dual optical paths to super-impose the head-up display symbology onto the scene photographed via the forward field of view of the camera. The camera does not look through the HUD combining glass, and therefore can be mounted to minimize obstruction of the pilot's forward field of view. Registration of the two optical paths is maintained by a fixed prism assembly mounted ahead of the camera lens. A precision mechanical interface between camera and HUD eliminates the necessity for boresight adjustment. The prism assembly compensates for sighting error due to windscreen curvature in front of the camera. The camera iris and shutter combine to provide 10 stops of exposure control, with automatic ambient light and frame rate compensation over a 6 stop range. The shutter angle is thumbwheel-adjustable to provide 4 stops of film ASA compensation in 13 steps. The film advance mechanism employs a shuttle and fixed register pin in the camera. The flight-replaceable magazine accommodates 100 foot film spools.
