The Boeing Sonic Cruiser was a Boeing concept for the development of a fast airliner with delta wing , duck wings as elevator and two vertical stabilizers .
history
Development began on March 29, 2001. As before, the company wanted to work with its successful “working-together principle”, ie development should take place in close coordination with interested airlines. The concept envisaged transporting 200–250 passengers over a distance of 11,000 to 16,600 km. The flight speed should be Mach 0.95-0.98, that would be 15% faster than normal commercial aircraft , which would have saved about an hour in time over a distance of 5000 km. The cruising altitude was about 45,000 ft (13,716 m). The concept was to fly directly from one city to another in a relatively small plane in order to avoid time-consuming transfers at a hub .
The Sonic Cruiser should comply with Chapter 4 noise regulations. In addition, the consumption should be at the level of the Boeing 767 .
The End
Due to the airlines' lack of interest in the Sonic Cruiser after the September 11, 2001 attacks , the project was canceled in autumn 2002. The reason for this was that the profitability of an aircraft type was more important to the airlines than the time it saved. Boeing then built the 787 , previously called the 7E7, with the aim of using 15–20% less fuel than comparable previous models.
