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).
At 36,000 feet (11,000 m) and Mach 1.7 (1,815 km/h; 1,128 mph), the heating conditions on the shock cone were similar to those at sea level and 650 knots (1,200 km/h; 750 mph) indicated airspeed, [i] but if the speed was increased to Mach 2.0 (2,136 km/h; 1,327 mph) at 36,000 feet (11,000 m), the shock cone was exposed to higher temperatures [j ...
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
Manned by Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg, the XB-1 launched in the early hours of Tuesday, reaching an altitude of 35,290 feet and accelerating to speed Mach 1. ...
The Boom Overture is a proposed Mach 1.7 (1,000 kn; 1,800 km/h; 1,100 mph), 65- to 88-passenger supersonic transport with a planned 4,250 nmi (7,870 km; 4,890 mi) of range. [26] With 500 viable routes, Boom suggests there could be a market for 1,000 supersonic airliners with business class fares. [9]
Mach number is more useful, and most high-speed aircraft are limited to a maximum operating Mach number, also known as M MO. For example, if the M MO is Mach 0.83, then at 9,100 m (30,000 ft) where the speed of sound under standard conditions is 1,093 kilometres per hour (590 kn), the true airspeed at M MO is 906 kilometres per hour (489 kn).
The single-seat jet, a 201-foot-long test model by Boom Supersonic, hit 844 mph just 12 minutes into its latest test flight out of California's Mojave Air and Space Port.
Typical speed of a modern high-speed train (e.g. latest generation of production TGV); a diving peregrine falcon—fastest bird; 320 km/h or 200 mph is a parameter sometimes used in defining a supercar.
