Computer Central Air Data, MC 0159A
This is an Air Data Computer from 1967 designed for the C-5A The Lockheed C-5 Galaxy is a large military transport aircraft built by Lockheed. It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability and has been operated by the USAF since 1969.
An Air Data Computer computes altitude, vertical speed, air speed, and mach number from sensor inputs such as pitot and static pressure and temperature. The early systems were electromechanical computers, and Elliotts backround wasas much in electronics as in precision gear making. After WWII Elliotts was acquired by Leon Bagrit who already managed Swift and Swallow on the Rochester site. During the Second World War the manufacturing company, styled B & P Swift Limited turned to war work, and manufactured aircraft equipment for the Ministry of Aircraft Production. This included flap and undercarriage actuators, which called for good gear and screw-cutting facilities and they also had a commercial arm making weighing scales which required gear wheels. Elliotts gained a precision gear capability and this can be seen in the early instruments such as this Air Data Computer,
