A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .
Jet airliners that entered service in the 1960s were powered by slim, low-bypass turbofan engines, many aircraft used the rear-engined, T-tail configuration, such as the BAC One-Eleven, Boeing 737, and Douglas DC-9 twinjets; Boeing 727, Hawker Siddeley Trident, Tupolev Tu-154 trijets; and the paired multi-engined Ilyushin Il-62, and Vickers VC10.
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines and the social and cultural changes fostered by commercial jet travel. Jet airliners were able to fly higher, faster, and farther than older piston ‑powered propliners , making transcontinental and intercontinental travel ...
As of July 2024 Embraer has delivered 3034 regional jets, between the ERJ family and the still in production E-Jet/E-Jet E2 [1] [2] The Sud Aviation Caravelle short-haul jet airliner was the first regional jet introduced in 1959 The Yakovlev Yak-40 was introduced in 1968 The Fokker F-28 was introduced in 1969 and was followed by the stretched Fokker 100 in 1988 and its Fokker 70 shrink in 1994.
The following is the list of purpose-built passenger jet airliners.It excludes turboprop and reciprocating engine powered airliners. It also excludes business jets and aircraft designed primarily for the transportation of air cargo.
A Falcon 900 behind a Falcon 2000. The Dassault Falcon is a family of business jets, manufactured by Dassault Aviation.Dassault produce the midsize Falcon 2000S/LXS twinjet, the long-range Falcon 900LX trijet and ultra-long range Dassault Falcon 7X/8X trijets.
Jet aircraft use airbreathing jet engines, which take in air, burn fuel with it in a combustion chamber, and accelerate the exhaust rearwards to provide thrust. Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner. Those with no rotating turbomachinery include the pulsejet and ramjet.
The first jet aircraft to fly was the Heinkel He 178 (Germany), flown by Erich Warsitz in 1939, followed by the world's first operational jet aircraft, the Messerschmitt Me 262, in July 1942 and world's first jet-powered bomber, the Arado Ar 234, in June 1943.
