Engineering:F-8 digital fly-by-wire project


The F-8 Digital-Fly-By-Wire (DFBW) project was an experimental digital fly-by-wire system developed by NASA at Armstrong Flight Research Center in the 1970s.[1] It was the first digital fly-by-wire fixed-wing aircraft without a mechanical backup.[2]
Based on a modified U.S. Navy Vought F-8C Crusader aircraft, it used a Apollo Guidance Computer as its control system.[3][4][5] The aircraft had the tail number NASA 802.[3]
The project was supported by Neil Armstrong, who advocated for the aircraft to be transferred to NASA.[3]
The system originally had an analog fly-by-wire backup, but this never needed to be used.[2][3]
The system's first completely digitally controlled flight was made on 25 May 1972, piloted by Gary E. Krier.[6]
The digital system was later upgraded to a triple-redundant digital system.[2][3]
