A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound in terms of air speed. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144.

2025年3月17日 · Concorde, the first supersonic passenger-carrying commercial airplane (or supersonic transport, SST), built jointly by aircraft manufacturers in Great Britain and France.

The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. It was intended to be much larger and faster than competing supersonic transport (SST) designs such as the Concorde. The SST was the topic of considerable concern within and outside the aviation industry.

2019年3月2日 · Half a century ago, the legendary supersonic passenger airliner Concorde made its first test flight, on March 2, 1969. The Concorde 001 prototype took off from Toulouse, piloted by André Turcat,...

2017年7月28日 · Commercial aircraft like Boeing’s Model 707 series and its Douglas competitor, the DC-8, ruled the air miles between major cities around the globe. However, the decade also became known for more than its share of aerospace failures, and among those failures lies the story of the American Supersonic Transport or SST.

The Japanese JAXA space agency began researching “the next generation SST”, with French involvement .This potential SST aircraft would fly 2-300 passengers, beyond Mach 2, to at least 11,000 km – Concorde’s travel distances were about 6,000 km – with a tenth of Concorde’s noise, a quarter of Concorde’s NOx pollution concentration ...

2023年10月14日 · 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.

北美航空sst早期设计就是放大版的xb-70。 机身被增长并放下客舱，而原本引擎前部的载弹舱换成了油箱。 由于各方面性能指标做为商用超音速客机不达标，这个方案很快就被否认了。

超音速客机（Supersonic Transport, SST）是指其速度比音速快的民航客机，历史上仅有两种超音速客机曾经批量生产并投入商业营运，分别为英国、法国联合研制的协和飞机，以及苏联的图-144，均在1960年代末出现。

During the 1950s, commercial air transport had made a radical shift from piston-powered airliners to the new jetliners like the Boeing 707. Going to an SST was simply the next logical step, and there was an economic rationale to it: move passengers faster, that …
