Frigate Ecojet
The Frigate Ecojet (in Russian: Фрегат Экоджет, transliterated as ''Fregat Ekodzhet''), is a program for the development of a new wide-body medium-haul civil aircraft using new aerodynamic, and design configurations. The project started in 1991 as the twinjet Tu-304 under the leadership of Valentin Klimov (then chief designer of the Tupolev design bureau), being initially projected to carry up to 500 passengers. Since 2004 the project has been carried out by a new design bureau, led by Valentin Klimov and instituted as a daughter company of Tupolev, headed by Valentin Klimov's son, Alexandr Klimov. Since 2017, the quadjet aircraft design has been branded the Frigate Freejet. Initial technical characteristics The primary goal of the Frigate Ecojet program was the development of a range of new wide-body medium-haul aircraft, intended to be operational by 2018. The new wide-body aircraft uses an oval fuselage configuration. The chosen form ensures minimal dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadjet
A four-engined jet, sometimes called a quadjet, is a jet aircraft powered by four Jet engine, engines. The presence of four engines offers increased power, allowing such aircraft to be used as airliners, Cargo aircraft, freighters, and military aircraft. Many of the first purpose-built jet airliners had four engines, among which stands the De Havilland Comet, the world's first commercial jetliner. In the decades following their introduction, their use has gradually declined due to a variety of factors, including the approval of Twinjet, twin-engine jets to fly farther from diversion airports as reliability increased, and an increased emphasis on fuel efficiency. Design Podded engines The engines of a four-engined aircraft are most commonly found in Podded engine, pods hanging from pylons underneath the wings. This can be observed in the Airbus A340, Airbus A380, and Boeing 747. Many military airlifters also feature this design, including the Antonov An-124, Boeing C-17 Globe ...
