boeing supersonic passenger jet

Work began on a full-sized mock-up and two prototypes in September 1969, now two years behind schedule. [citation needed], Its Soviet counterpart, the Tupolev Tu-144, was less successful, operating for only 55 passenger flights before being permanently grounded for various reasons.

The CL-823 was the largest of the first-round entries, with typical seating for 218. The proposal also included optional fuselage stretches that increased capacity from the normal 150 seats to 227. Due to concerns about jet blast, the four engines were moved to a position underneath an enlarged tailplane. Boeing faces several competitors for these high-speed passenger planes.

[1] Most of the designs featured a large delta wing, but in 1959 another design was offered as an offshoot of Boeing's efforts in the swing-wing TFX project (which led to the purchase of the General Dynamics F-111 instead of the Boeing offering). [10] But TWA had to compete with Pan Am. Production aircraft could start being built in early 1969, with the flight testing in late 1972 and certification by mid-1974.[14]. A key design feature of the 2707 was its use of a swing wing configuration. Boeing unveiled a new hypersonic passenger plane concept at the AIAA Aviation Forum 2018 in Atlanta on June 26, 2018.

Il aurait été assemblé dans les ateliers de Boeing à Renton, Washington, mais le coût très élevé du projet et les réactions sur les effets environnementaux (notamment le passage du mur du son) menèrent à l'annulation du projet en 1971 avant que les deux prototypes ne soient achevés, seule la maquette de test avait réussi à voir le jour. However, this project never went ahead beyond initial mockups, as the rise of fuel prices in 1973 and the legislation introduced to curb sonic booms shut down the program.
Service entry was only secured through large government funding subsidy.

The company had previously been partnered with both Lockheed and Airbus. [4], By mid-1962, it was becoming clear that tentative talks earlier that year between the British Aircraft Corporation and Sud Aviation on a merger of their SST projects were more serious than originally thought. New York, Boeing originally set out to make their own supersonic aircraft to rival the Concorde back in the 1960s and 1970s, called the Boeing 2707. The new design was also smaller, seating 234, and known as the Model 2707-300. Receive mail from us on behalf of our trusted partners or sponsors? The supercritical wing was originally developed as part of the SST efforts in the U.S., but is now widely used on most jet aircraft.
[28], At the time, there were 115 unfilled orders by 25 airlines, while Concorde had 74 orders from 16 customers.
