Concorde is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million . Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December.
The Tupolev Tu-144 is a Soviet supersonic passenger airliner designed by Tupolev in operation from 1968 to 1999.
The Boeing 2707 was an American supersonic passenger airliner project during the 1960s. After winning a competition for a government-funded contract to build an American supersonic airliner, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. It was intended to be much larger and faster than competing supersonic transport (SST) designs such as Concorde.
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.
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. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again.
The Boeing Sonic Cruiser was a concept jet airliner with a delta wing–canard configuration. It was distinguished from conventional airliners by its delta wing and high-subsonic cruising speed of up to Mach 0.98. Boeing first proposed it in 2001, but airlines generally preferred lower operating costs over higher speed. Boeing ended the Sonic Cruiser project in December 2002 and shifted to the slower, but more fuel-efficient 7E7 airliner.
A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound. Supersonic aircraft were developed in the second half of the twentieth century. Supersonic aircraft have been used for research and military purposes, but only two supersonic aircraft, the Tupolev Tu-144 and the Concorde, ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.
Aerion Corporation was an American aircraft manufacturer based in Reno, Nevada. It was founded by Robert Bass of Fort Worth.
The SAI Quiet Supersonic Transport (QSST) was a project by Supersonic Aerospace International (SAI) to develop a "virtually boomless" commercial supersonic business jet. The project was announced around the year 2000 and provided update announcements until 2010. After three years without any updates, the last update was in 2013. As of 2023, there have been no more updates, and the project appears to have been abandoned.
Quiet Spike was a collaborative program between Gulfstream Aerospace and NASA's Dryden Flight Research Center to investigate the suppression of sonic booms. The patent was published with the United States Patent and Trademark Office in 2004 and is owned by Gulfstream Aerospace.
The High Speed Civil Transport (HSCT) was the focus of the NASA High-Speed Research (HSR) program, which intended to develop the technology needed to design and build a supersonic transport that would be environmentally acceptable and economically feasible. 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.
The Gulfstream X-54 is a proposed research and demonstration aircraft, under development in the United States by Gulfstream Aerospace for NASA, that is planned for use in sonic boom and supersonic transport research.
The Zero Emission Hyper Sonic Transport or ZEHST is a planned hypersonic passenger jet airliner project by the multinational aerospace conglomerate EADS and the Japanese national space agency JAXA.
The Aerion AS2 was a proposed supersonic business jet that was being developed by Aerion Corporation. In May 2014, it was announced that the Aerion AS2 would be part of a larger Aerion SBJ redesign, which aimed for release after a seven-year developmental period. Aerion partnered with Airbus in September the same year. In December 2017, Airbus was replaced by Lockheed Martin. Its General Electric Affinity engine was unveiled in October 2018. In February 2019, Boeing replaced Lockheed Martin. Development stopped when Aerion ceased operations in May 2021.
The Lockheed Martin X-59 Quesst, sometimes styled QueSST, is an American experimental supersonic aircraft being developed at Skunk Works for NASA's Low-Boom Flight Demonstrator project. Preliminary design started in February 2016, with the X-59 planned to begin flight testing in 2021. After delays, as of January 2024, it is planned to be delivered to NASA for flight testing in 2024. It is expected to cruise at Mach 1.42 at an altitude of 55,000 ft (16,800 m), creating a low 75 effective perceived noise level (EPNdB) thump to evaluate supersonic transport acceptability.
The Boom XB-1 "Baby Boom" is a one-third-scale trijet supersonic demonstrator designed by Boom Technology as part of development of the Boom Overture supersonic transport airliner. Powered by three General Electric J85s, it is planned to maintain Mach 2.2, with over 1,000 nautical miles of range. Taxi tests began in December 2022.
The Boom Overture is a proposed Mach 1.7, 64–80 passenger supersonic airliner with 4,250 nmi of range, which is planned to be introduced in 2029 by Boom Technology. The company claims that with 500 viable routes, there could be a market for 1,000 supersonic airliners with business class fares. It had gathered 76 commitments by December 2017. The aircraft is planned to have a delta wing configuration, but will be built with composite materials. Following a redesign revealed in 2022 it is intended to be powered by four dry (non-afterburning) 35,000 lbf (160 kN) turbofans. Regulations for takeoff noise or overland boom can be met or changed.
Many aviation-related events took place in 2022. Throughout the year, the aviation industry was recovering from the COVID-19 pandemic.
The Boom Symphony is a medium-bypass turbofan engine under development by Boom Technology for use on its Overture supersonic airliner. The engine is designed to produce 35,000 pounds of thrust at takeoff, sustain Overture supercruise at Mach 1.7, and burn sustainable aviation fuel exclusively.
