Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires, and flight control computers determine how to move the actuators at each control surface to provide the ordered response.
In fly-by-wire systems the valves, which control these systems, are activated by electrical signals. In power-by-wire systems, electrical actuators are used in favour of hydraulic pistons. The power is carried to the actuators by electrical cables. These are lighter than hydraulic pipes, easier to install and maintain, and more reliable.
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather fighter aircraft designed by McDonnell Douglas (now part of Boeing ). Following reviews of proposals, the United States Air Force (USAF) selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter.
The McDonnell Douglas (now Boeing) F-15E Strike Eagle is an American all-weather multirole strike fighter [ 5] derived from the McDonnell Douglas F-15 Eagle. The F-15E was designed in the 1980s for long-range, high-speed interdiction without relying on escort or electronic-warfare aircraft. United States Air Force (USAF) F-15E Strike Eagles can ...
Abstract representation of a Fly-By-Wire flight system. Flight control computer (FCC) is a primary component of the avionics system found in fly-by-wire aircraft. It is a specialized computer system that can create an artificial flight characteristics and improve handling characteristics by automating a variety of in-flight tasks which reduce the workload on the cockpit flight crew.
The first operational fully authoritative fly-by-wire system was developed for the General Dynamics F-16 Fighting Falcon and its introduction in 1978 heralded a revolution in taking over the task of ensuring stability in flight from the traditional aerodynamic stabilizers. This use of "relaxed static stability" allowed aircraft to be made more ...
McDonnell Douglas F/A-18 Hornet. The Northrop YF-17 (nicknamed "Cobra") was a prototype lightweight fighter aircraft designed by Northrop aviation for the United States Air Force 's Lightweight Fighter (LWF) technology evaluation program. The LWF was initiated because many in the fighter community believed that aircraft like the F-15 Eagle were ...
Occupations. Engineer. Test pilot. Parent. Henri Ziegler. Bernard Ziegler (12 March 1933 – 4 May 2021) [1] was a French pilot and engineer, who served in Airbus as senior vice president for engineering, well known for his evangelical zeal for the application of the fly-by-wire system in the Airbuses. He was the son of Airbus founder Henri ...
