Paper Abstract

The 11F-5E single cockpit tactical reconnaissance aircr;i.ft was designed in 1981 to carry a variety of low, medium, and high altitude sensor configurations mounted internally on interchangeable pallets. Recently,. Northrop has incorporated CAI's high resolution KS-147A LOROP (Long Range Oblique Photographic) camera into the aircraft to provide long-range standoff capability., Key features of the KS-147A camera include a 66-inch focal length, f/5.6 lens; closed loop autofocus; two axis, gyro-stabilized scan head, and a passive isolation mount to reduce aircraft motion inputs; a self-contained thermal system to stabilize temperature-sensitive optics; and all electronics required to control camera-to-aircraft interface functions. Key aircraft changes to accommodate the camera include a new three-sided camera bay lower door with side oblique windows, a new stronger camera-mounting pallet, a new cockpit forward control panel, new temperature control system ducts, new wire harnesses, and new side oblique sights., This paper addresses laboratory and flight test activities conducted on the KS-147A camera and the RF-5E aircraft. Included are development and qualification testing of the camera, preflight thermal conditioning. tests of the camera in the aircraft, and finally, a detailed discussion of the flight testing at Edwards AFB, and verification of the in-flight photo resolution requirement of 70 line pairs per mm.
