Such a layout would still have good supersonic performance, but also have reasonable take-off and landing speeds using vortex generation. [11] The aircraft would have to take off and land very "nose high" to generate the required vortex lift, which led to questions about the low speed handling qualities of such a design. [13]
Partial reheat providing a 20% thrust increase [3] was installed to give the take-off thrust required for Concorde to operate from existing runways, and for transonic acceleration from Mach 0.95 up to Mach 1.7; the aircraft flew supersonically without reheat above that speed. At cruise the engine's direct contribution (transferred by its mounts ...
With a legacy of more than 100 years, the Better Business Bureau (BBB) is the go-to watchdog for evaluating businesses and charities. The nonprofit organization maintains a massive database of ...
Complaints lodged with the BBB fell about 7%, to 927,000. In practical terms, those numbers suggest that more Americans are being smart about their shopping, looking into businesses' reputations ...
On 25 July 2000, Air France Flight 4590 crashed shortly after take-off with all 109 occupants and four on ground killed; the only fatal incident involving Concorde. Commercial service was suspended until November 2001, and Concorde aircraft were retired in 2003 after 27 years of commercial operations.
As the first and only supersonic commercial jetliner, Concorde was popular with royals, celebrities, and business executives.
The Better Business Bureau (BBB) is an American private, 501(c)(6) nonprofit organization founded in 1912. BBB's self-described mission is to focus on advancing marketplace trust, [2] consisting of 92 independently incorporated local BBB organizations in the United States and Canada, coordinated under the International Association of Better Business Bureaus (IABBB) in Arlington, Virginia.
Different engine configurations, BOl.21, BOl.21/2 and BOl.23, with either reheat or an aft fan, were proposed for this aircraft to provide the required increase in take-off thrust.
