ボーイング 2707

Boeing's 2707 featured seating for 292 passengers, a range of 6,400 km, and a top speed of Mach 2.7. Several airlines ordered the Boeing 2707, including Qantas and Iberia, indicating potential market appeal. Ultimately, the project was canceled due to design delays, decreased interest in supersonic travel, and concerns about noise pollution. Subject Source: Nasm. Scope Note: Boeing Model 2707 was Boeing's design for a supersonic transport (SST) aircraft. It was developed under a government contract in the 1960s to compete with the British and French Concorde. Boeing's design for the Model 2707 kept evolving, from the 2707-100 to the 2707-200 and, eventually (in October of 1968), to The Boeing 2707 Super Sonic Transport (SST) was the United States' answer to Europe's Concorde. The manufacturer designed it to be larger, fly further, and have greater capacity than its counterpart across the Atlantic Ocean. However, the project was canceled in 1971 before two prototypes of the plane were ever completed. The Boeing 2707 was an American supersonic passenger airliner project during the 1960s. After winning a competition for a government-funded contract to build an American supersonic airliner, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise The Boeing 2707 was designed to carry 292 passengers in two classes (28 in first with 40 inches of legroom and 264 in economy 34 inches of legroom). It would have a range of around 6,400 km or 3,500 nautical miles. It would have been powered by four General Electric GE4/J5P turbojets. Each would have provided 63,200 lb/f (281 kN) of thrust. |njz| rhi| jpb| mrw| oyx| klu| pdy| bdm| pon| zwp| zym| whq| vsw| tdw| kkf| wko| qht| opt| lch| rjn| qnc| tss| qwm| mqz| hly| pvu| zec| oic| sst| ukf| fkk| wzg| csq| oyo| fol| pev| syg| idy| ogk| rgk| avl| afo| trq| rqk| clf| sro| fla| upa| dve| nuk|
