Description
Northwest Airlines Boeing Sonic Cruiser 797
he Boeing Sonic Cruiser was a near-transonic concept aircraft proposed by Boeing Commercial Airplanes in 2001. Its distinguishing feature was to be its high-subsonic cruising speed, faster than conventional jet airliners.
Design and development
The Sonic Cruiser concept developed from studies beginning in the late 1990s.[1] A variety of concepts were studied, including supersonic aircraft, aircraft with the engines mounted above the wing, aircraft with a single vertical tail, and aircraft with rectangular intakes. The initial sketches released to the public were highly conjectural. A patent drawing filed by Boeing on March 22, 2001 put the baseline aircraft's dimensions at 250 feet (76 m) in length, with a wingspan of 164.9 feet (50.3 m).
The Sonic Cruiser was born from one of numerous outline research and development projects at Boeing with the goal to look at potential designs for a possible new near-sonic or supersonic airliner.[2] The strongest of these initial concepts was dubbed the "Sonic Cruiser" and publicly unveiled on March 29, 2001,[3] shortly after the launch of the A380 by rival Airbus. Boeing had recently withdrawn its proposed 747X derivative from competition with the A380 when not enough airline interest was forthcoming, and instead proposed the Sonic Cruiser as a completely different approach.[2]
Instead of the A380's massive capacity, requiring a hub and spoke model of operation, the Sonic Cruiser was designed for rapid point-to-point connections for 200 to 250 passengers.[4] With delta wings and flying just short of the speed of sound at Mach 0.95-0.98 (about 627 mph or 1,010 km/h at altitude), the Sonic Cruiser promised 15-20% faster speed than conventional aircraft without the noise pollution caused by the sonic boom from supersonic travel. The aircraft design was to fly at altitudes in excess of 40,000 ft (12,000 m), and a range somewhere between 6,000 nautical miles (11,000 km) and 10,000 nautical miles (19,000 km).[4] Boeing estimated the Sonic Cruiser's fuel efficiency to be comparable to current wide body twin-engine airliners.[4]
Wind tunnel testing and computational fluid dynamics analysis further refined the Sonic Cruiser concept. Based on artwork released by Boeing in July 2002, the Sonic Cruiser now sported two taller vertical tails with no inward cant. The forward canard was set at zero degrees dihedral. At this point, Boeing had yet to decide on the size or layout of the aircraft's fuselage cross section.[citation needed]
Cancellation
In the end, most airlines favored lower operating costs over a marginal increase in speed, and the project did not attract the interest Boeing had been hoping for. The Sonic Cruiser project was finally abandoned by December 2002 in favor of the slower but more fuel-efficient 7E7 (later renamed Boeing 787 Dreamliner).[5] Much of the research from the Sonic Cruiser was applied to the 787, including carbon fiber reinforced plastic for the fuselage and wings, bleedless engines, cockpit and avionics design.[6]
