Thus Mach 2 is 1520 mph at sea level, but only 1320. The factors that effect the speed of sound are not random effects based on a whim but exact scientific principles that effect the speed of sound. The reason for this is that the speed of sound changes. That is only part of the story and it is only partially true. However, it is primarily and more directly related to molecular speed and thus temperature than it is to anything else. Mach values are relative to the speed of sound at any given altitude. In school they teach the speed of sound is 1,126 feet per second. The fact that pressure and density change with altitude leads. One might also note that the temperature is lower as one ascends primarily because the pressure is lower as one ascends and then conclude that the speed difference is equally attributable to lower pressure (or lower density for that matter). We could therefore expect that density will play a significant part in the sound speed of air.
Since molecular speed in a gas is a direct function of average molecular kinetic energy and that is a direct function of temperature, the speed of sound in a gas will also be a function of temperature.Īt the cruise altitude of the Concorde the atmospheric temperature is below that of the standard atmospheric temperature at sea level, so the speed of sound is also lower. Therefore, the sound wave can not possibly move through the gas at a speed greater than that of the individual molecules themselves, and in fact must move at a lower speed than that due to the random nature of molecular movement. Window.dataLayer = window.A sound wave moving through a gas requires a small scale bulk movement of gas molecules back and forth as pressure at any locations builds or falls.

The general downturn in the commercial aviation industry after the September 11 attacks in 2001, and the ceasing of maintenance support for Concorde by Airbus (the successor company of both Aérospatiale and BAC), also contributed. 25, 2000, in which all passengers and crew were killed. The type was eventually retired in 2003 after the crash of Air France Flight 4590 on Jul. Kennedy International Airport in New York, Washington Dulles International Airport and Grantley Adams International Airport in Barbados it flew these routes in less than half the time of other airliners. The supersonic airliner flew regular transatlantic flights from London’s Heathrow Airport and Paris’s Charles de Gaulle Airport to John F. It had a maximum speed of Mach 2.04 (1,354 mph or 2,180 km/h at cruise altitude, over twice the speed of sound), with seating for 92 to 128 passengers. The aircraft entered service in 1976 and continued flying for the next 27 years.Ĭoncorde, which was jointly developed and manufactured by Aérospatiale and the British Aircraft Corporation (BAC) under an Anglo-French treaty, was built in twenty samples including six prototypes and development aircraft.Īir France (AF) and British Airways (BA) were the only airlines to purchase and fly Concorde. 7, 1996 when it completed the New York to London flight in 2 hours 52 minutes and 59 seconds.Īérospatiale/ BAC Concorde was a British-French supersonic passenger jet airliner.
Noteworthy Concorde’s fastest transatlantic crossing was on Feb. After racing to catch the Concorde and struggling to keep up, the Tornado broke off the rendezvous after just four minutes, while Concorde cruised serenely on to JFK! Mach 1.0 is the speed of sound in air, so a plane flying Mach 2.0 is flying twice as fast as the speed of sound.
