In November, another design review was held, and by this time Boeing had scaled up the original design into a 250-seat model, the Model 733-290. [34], Nevertheless, the SST race has had several lasting effects on the industry as a whole. [13], The North American NAC-60 was essentially a scaled-up B-70 with a less tapered fuselage and new compound-delta wing. Featuring new add-ons, products and industry news. If fuel costs were to change dramatically, SSTs would not be competitive. Like the Concorde, it featured a long and skinny fuselage, engines under the wing, and a compound delta planform. The proposal also included optional fuselage stretches that increased capacity from the normal 150 seats to 227. The inherently lower lift-to-drag ratios at supersonic speeds mean SSTs will have poorer fuel economy than subsonic designs. This also meant it would fly slower, at Mach 2.65.[13]. A promotional film claimed that airlines would soon pay back the federal investment in the project, and it was projected that SSTs would dominate the skies with subsonic jumbo jets (such as Boeing's 747) being only a passing intermediate fad.

The Boeing 2707 was intended to be the first American supersonic airliner, but increasing outcry over the environmental effects, notably the sonic boom, led to its cancellation in 1971 before the two prototypes had been completed. [22][23] Fahey expressed the opinion that this would not be a fatal obstacle for an advanced SST development.[24]. Considerable wind tunnel testing of the various models was carried out at NASA's Langley Research Center. The package features FSX compatible gauges for the 2D panel, a new basic VC and new smoke effects.

[3] The study was prompted in the wake of several accidents, which led to the belief that the industry was becoming moribund. Presidential Adviser Russell Train warned that a fleet of 500 SSTs flying at 65,000 ft. for a period of years could raise stratospheric water content by as much as 50% to 100%. [4], The basic concept behind the SST was that its fast flight would allow them to fly more trips than a subsonic aircraft, leading to higher utilization.

"[19], In March 1971, despite the project's strong support by the administration of President Richard Nixon, the U.S. Senate rejected further funding. A major change in the design came when Boeing added canards behind the nose—which added weight. [citation needed] These few aircraft went on to have a very long in-service flight life and were claimed to be ultimately commercially successful for their operators, until finally removed from service in the aftermath of the type's only crash in 2000 and the 9/11 terrorist attacks when Airbus decided to end servicing arrangements. As if this were not enough, it soon became known that the Soviets were also working on a similar design. Rising costs and the lack of a clear market led to its cancellation in 1971 before two prototypes had been completed. Through the second half of the 1970s, NASA provided funding for the Advanced Supersonic Transport (AST) project at several companies, including McDonnell Douglas, Boeing, and Lockheed.

Lockheed's entry, designated CL-823, was essentially an enlarged Concorde. During the 1970s the alleged potential for serious ozone damage and the sonic boom worries were picked up by the Sierra Club, the National Wildlife Federation and the Wilderness Society.

Lockheed's L-2000 was judged simpler to produce and less risky, but its performance was slightly lower and its noise levels slightly higher. It was one of the earliest wide-body aircraft designs, with 2-3-2 row seating arrangement at its widest section[14] in a fuselage that was considerably wider than aircraft then in service. A counterattack was organized under the banner of the "National Committee for an American SST", which urged supporters to send in $1 to keep the program alive. In Europe, the cooperation that allowed Concorde led to the formation of Airbus, Boeing's foremost competitor. The SST mock-up included both overhead storage for smaller items with restraining nets, as well as large drop-in bins between sections of the aircraft.

[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). [18], By this point, the opposition to the project was becoming increasingly vocal. Other concerns were also added to the list, although the evidence for them was essentially non-existent. [9] A report from the Supersonic Transport Advisory Group (STAG) followed, noting that the European team was in the lead in basic development, and suggested competing by developing a more advanced design with better economics. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. One was that the water vapor released by the engines into the stratosphere would envelop the earth in a "global gloom". Copyright © 2020 Fly Away Simulation. 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. Flexing of the fuselage (it would have been the longest ever built) threatened to make control difficult. [dubious – discuss] As the most advanced supersonic transports became some of the oldest airframes in the fleet, profits eventually fell, due to rising maintenance costs.[38]. The final-configuration Boeing 2707 mockup was sold to a museum and displayed at the SST Aviation Exhibit Center in Kissimmee, Florida, from 1973 to 1981. #epicfail. The Boeing 2707 was one of the first commercial aircraft designed with a glass cockpit. Included are two textures.

Copy the Boeing 2707 SST folder into your FSX/ Simobjects/ aircraft folder. The package features FSX compatible gauges for the 2D panel, a new basic VC and new smoke effects. Boeing also faced insurmountable weight problems due to the swing-wing mechanism (a titanium pivot section having been fabricated with a weight of 4,600 pounds and measuring eleven feet long and 2.5 feet thick)[15] and the design could not achieve sufficient range.

After much testing, the Boeing 2707 design was chosen as the winner on 1 st January 1967.

Halaby argued that a failure to enter this market would be a "stunning setback". The package features FSX compatible gauges for the 2D panel, a new basic VC and new smoke effects.

The new design was also smaller, seating 234, and known as the Model 2707-300. [5] In spite of marginal economics, nationalistic and political arguments had led to wide support for the project, especially from Charles de Gaulle. Boeing predicted that if the go-ahead were given, construction of the SST prototypes would begin in early 1967 and the first flight could be made in early 1970.

Service entry was only secured through large government funding subsidy. [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 content of the comments below are entirely the opinions of the individual posting the comment and do not always reflect the views of Fly Away Simulation. The design resembled the future B-1 Lancer bomber, with the exception that the four engines were mounted in individual nacelles instead of paired pods used on the Lancer.

FSX – Boeing 2707 SST Updated. Will there ever be a working 3d virtual cockpit for this? The CL-823 lacked any form of high-lift devices on the wings, relying on engine power and long runways for liftoff, ensuring a huge noise footprint. You will be flying one version or another by 1980 and be trying to remember what the great debate was all about. A key design feature of the 2707 was its use of a swing wing configuration.

When this occurred, Boeing's design was now the 300-seat Model 733-390.

[29] The two prototypes were never completed. [33], Though many designs have been studied since, it is unlikely SST aircraft will be economically feasible in the near future.

The only major design difference was the use of individual pods for the engines, rather than pairs. AFL-CIO President George Meany suggested that the race to develop a first-generation SST was already lost, but the US should "enter the competition for the second generation —the SSTs of the 1980s and 1990s.
