Aircraft Noise Generation and Assessment Section 5-Overall Vehicle System Noise, Part d-Sonic Boom.. There has been a renewed interest globally in civil supersonic overland flight that has fostered numerous research and technology development activities. It is now possible to design a low-boom aircraft with a carefully tailored vehicle shape that controls the far field pressures and minimizes sonic booms on the ground. This section will describe recent international advances and cooperative research in sonic boom design, propagation modeling, and human subjective response in preparation of potential international rule changes that will permit civil supersonic flight over land..

A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. The crack of a supersonic bullet passing overhead, the crack of a bullwhip, and the snapping of a rolled up towel are all examples of small sonic booms. Sonic booms due to large supersonic aircraft can be particularly loud and startling, tend to awaken people, and may cause minor damage to some structures. This led to the prohibition of routine supersonic flight overland. Although sonic booms cannot be completely prevented, research suggests…

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 in terms of air speed. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144, although the Boom Technology Overture SST may succeed in starting service around 2029, which would make it the third operational SST. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003, ferry flight being its last flight. Following the termination of flying by Concorde, there have been no SSTs in c…

The North American Aviation XB-70 Valkyrie is a retired prototype version of the planned B-70 nuclear-armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. Designed by North American Aviation in the late 1950s, the Valkyrie was a large six-engine, delta-winged aircraft able to fly Mach 3+ at an altitude of 70,000 feet (21,000 metres). At these speeds, it was expected that the B-70 would be practically immune to interceptor aircraft, the only effective weapon against bomber aircraft at the time. The bomber would spend only a brief time over a particular radar station, flying out of its range before the controllers could position their figh…

An airplane (American English), or aeroplane (Commonwealth English), also plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remot…

Concorde ( KONG-kord, French: [kɔ̃kɔʁd] ) is a retired Anglo-French supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation (BAC). Studies began in 1954 and a UK–France treaty followed in 1962, as the programme cost was estimated at £70 million (£1.77 billion in 2025). Construction of six prototypes began in February 1965, with the first flight from Toulouse on 2 March 1969. The market forecast was 350 aircraft, with manufacturers receiving up to 100 options from major airlines. On 9 October 1975, it received its French certificate of airworthiness, and was certified by the UK CAA on 5 December. Concorde is an aircraft design with a narrow…
