摘要

In March 2001 Boeing unveiled its Sonic Cruiser concept for a sleek future airliner, featuring twin tails, a delta wing and canards, that promised a 15 to 20% faster cruise speed than conventional airliners. Wind tunnel tests and computational fluid dynamics research were carried out, and some carriers, including Continental Airlines, gave the concept a positive reception. Then 9/11 happened. The subsequent airline industry slump underlined the importance of efficiency to carriers. During 2002, interest in future concepts among Boeing's customer advisory groups moved away from the Sonic Cruiser and towards a separate concept for a mid-size, twin-engine Super Efficient Airliner that other Boeing engineers were simultaneously working on.
