Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).
A supersonic transport (SST) is a civil aircraft designed to transport passengers at speeds greater than the speed of sound. The only supersonic civilian aircraft to see service were the Soviet produced Tupolev Tu-144 which first flew in 1968 and last transported passengers in 1978, with NASA retiring it from any use in 1997; and the Franco ...
A supersonic aircraft is an aircraft which can exceed the speed of sound (Mach 1.0) in level flight. Type ... Dual jet and rocket powerplants,
Mach 2.02 (~2,154 km/h or 1,338 mph) cruising speed [73] for optimum fuel consumption (supersonic drag minimum and turbojet engines are more efficient at higher speed); [74] fuel consumption at Mach 2 (2,120 km/h; 1,320 mph) and at altitude of 60,000 feet (18,000 m) was 4,800 US gallons per hour (18,000 L/h).
The plane was born out of a competition between Boeing and North American Aviation, then a major aerospace manufacturer that was eventually chosen by the Air Force, in 1957, to develop a bomber ...
A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA.
And flying at twice the speed of sound was no longer sustainable. ... Environmentally, the carbon footprint of the supersonic jet was off the scale. The fuel burn for Concorde was four times more ...
The Boom Overture is a supersonic airliner under development by Boom Technology, designed to cruise at Mach 1.7 or 975 knots (1,806 km/h; 1,122 mph). It will accommodate 64 to 80 passengers, depending on the configuration, and have a range of 4,250 nautical miles (7,870 km; 4,890 mi).
