The aircraft was to be a future supersonic passenger aircraft, baselined to cruise at Mach 2.4, or more than twice the speed of sound. The project started in 1990 and ended in 1999. [1] It was meant to cross the Atlantic or the Pacific Ocean in half the time of a non-supersonic aircraft. It was also intended to be fuel efficient, carry 300 ...
The vehicle design was intended to have about 20,000 kilometres (11,000 nautical miles) range and good subsonic and supersonic speed fuel efficiency, thus avoiding the problems inherent in earlier supersonic aircraft. The top speed is projected to be Mach 5+.
In March 2016, Boom Technology revealed that it is in the development phases of building a 40-passenger supersonic jet capable of flying Mach 1.7, claiming that the design simulation shows that it will be quieter and 30% more efficient than the Concorde and will be able to fly Los Angeles to Sydney in 6 hours. It is planned to go into service ...
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
The company claims the aircraft will have a cruise speed of Mach 5 with a capacity of 25 passengers. [35] Destinus L A not-yet-built concept for an aircraft capable of transporting up to 400 passengers to any destination in the world within two to three hours, according to the company's claims. This aircraft will have a cruise speed of Mach 6. [36]
LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) was a 36-month European FP6 study to examine ways to produce engines for a Mach number 4-8 hypersonic flight aircraft. The project ended in April 2008. [1] It was funded by the European Commission research and development fund (rather than ESA), and cost 7 million euros. [2] [3]
Cruising speed in the air is said to be 170 kilometres per hour (92 kn) Range is estimated as 1,000 kilometres (620 mi), at a height of 2,500 metres (8,200 ft). The current version of the car can reach heights of 4,572 metres (15,000 ft). It is said to take two minutes and 15 seconds to transform from car into aircraft. [8]
In August 2020, Hermeus received a $1.5 million contract from the United States Air Force to develop their proposed aircraft and function as a possible Air Force One. [6] They are building the supersonic Quarterhorse Mk 2 with an advanced engine based on the Pratt & Whitney F100. Quarterhorse Mk 2 is expected to hit speeds greater than Mach 2.5.
