SST - SST

Japanese: SST - エスエスティー

A transport aircraft that travels at supersonic speed (usually 2 to 3 times the speed of sound). Abbreviation for super-sonic transport. If it travels at more than twice the speed of sound, it can achieve the same fuel efficiency as a general jet transport aircraft that cruises at about 0.8 times the speed of sound. Since the mid-1950s, research on supersonic transport has been active in various countries, and the Concorde jointly developed by the UK and France began commercial operation in 1976, and the former Soviet Union's Tupolev Tu-144 began commercial operation in 1977. However, Concorde caused noise pollution in residential areas, as well as low operating efficiency and rising fuel costs, which led to huge losses for both British and French airlines, and production was discontinued in 1979 after 16 mass-produced aircraft, and operation was suspended in 2003. Both production and operation of the Tu-144 were discontinued. Later, in June 2005, the Japanese and French aerospace industry societies agreed to jointly research the next generation of SST.

超音速で運航（ふつうは音速の２〜３倍）する輸送用の航空機。super-sonic transport（超音速輸送機）の略。音速の２倍以上の飛行なら，音速の0.8倍程度を巡航速度とする一般のジェット輸送機と同じくらいの燃費が達成できる。1950年代半ば以降各国で研究が盛んになり，英仏共同開発のコンコルドが1976年から，旧ソ連のツポレフTu-144が1977年から営業運航に入った。しかし，コンコルドは住居地域にあたえる騒音公害のほか稼効率の低さや燃料費高騰などにより英仏両国の航空会社とも巨大な赤字運航となり，生産は量産型16機で1979年に打ち切られ，2003年運航停止。Tu-144は生産・運航とも中止。その後，2005年６月，日本とフランスの航空宇宙工業会は次世代SSTの共同研究で合意した。
