SonicStar
HyperStar is a proposed supersonic jet airliner designed by HyperMach CEO Richard H. Lugg. Lugg said, in a 2016 ''Altitudes Aviation'' interview and at a 2014 presentation at the Global Aerospace Summit in Abu Dhabi, that he plans to have the hypersonic transport airborne by June 2028. The HyperStar is expected to reach speeds of up to Mach number 3.6 () and fly at an altitude of 80,000 feet (24,380 m). Its propulsion is projected to be 30 percent more fuel efficient than the Rolls-Royce/Snecma Olympus 593 Engine which flew the Concorde. Hypothetically, the HyperStar would fly three times faster than the speed of the Concorde. It is planned to be powered by two engineered 157,700 thrust SonicBlue HYSCRAM (Hypersonic Superconducting Combustion Ram Accelerated Magnetohydrodynamic Drive ) hybrid hypersonic 6500-X series engines. Sonic boom is expected to be eliminated over land, through electromagnetic drag reduction technology currently under development. The propos ...

Supersonic Aircraft
A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach number 1). Supersonic speed, 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 (first flown on December 31, 1968) and the Concorde (first flown on March 2, 1969), ever entered service Supersonic transport, for civil use as airliners. Fighter aircraft, Fighter jets are the most common example of supersonic aircraft. The aerodynamics of supersonic flight is called compressible flow because of the compression (physics), compression associated with the shock waves or "sonic boom" created by any object traveling faster than sound. Aircraft flying at speeds above Mach 5 are called Hypersonic flight, hypersonic aircraft. History The first aircraft to fly supersonic in level flight was the American Bell X-1 exper ...

Zero Emission Hyper Sonic Transport
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. On 18 June 2011, the ZEHST concept was unveiled by EADS at the Le Bourget Air Show. The envisioned vehicle uses a combination of three different types of engines, including relatively conventional turbofans, rocket motors, and scramjets to attain a maximum speed of Mach 4.5 (four and a half times the speed of sound). The ZEHST has been projected to carry between 50 and 100 passengers while flying at very high altitudes for greater efficiency. Conceptually, the ZEHST has been promoted as a descendant of, or a successor to, Concorde, a supersonic airliner that was withdrawn from passenger routes in 2003. According to projections released, the ZEHST would be capable of flying between Paris and Tokyo in 2.5 hours, or between New York and London within one hour. During 2011, EADS st ...

SpaceLiner
SpaceLiner is a concept for a suborbital, hypersonic, winged passenger supersonic transport, conceived at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, or DLR) in 2005. In its second role the SpaceLiner is intended as a reusable launch vehicle (RLV) capable of delivering heavy payloads into orbit. The SpaceLiner is a very long-term project, and does not currently have funding lined up to initiate system development as of 2017. Projections in 2015 were that if adequate funding was eventually secured, the SpaceLiner concept might become an operational spaceplane in the 2040s. Concept The SpaceLiner concept consists of a two-stage, vertical takeoff, horizontal landing configuration with a large uncrewed booster and a crewed stage designed for 50 passengers and 2 crew members. The fully reusable system is accelerated by a total of eleven liquid rocket engines (9 for the booster stage, 2 for the passenger stage), which are to be operated using cryogenic ...

Aerion SBJ
The Aerion SBJ was a supersonic business jet project designed by American firm Aerion Corporation. Unveiled in 2004, the designer sought a joint venture with a business aircraft manufacturer for a $1.2–1.4 billion development in 7–8 years. Aerion received 50 letters-of-intent before enlarging the design as the Aerion AS2 in 2014. Powered by two Pratt & Whitney JT8D-219 engines, the $80 million aircraft was to transport 8–12 passengers up to Mach 1.6 and up to . Aerion abruptly announced on May 21, 2021 that it will be shutting down due to inability to raise capital. Development In 2003, Aerion commenced a search for a large aerospace partner, including Bombardier Aerospace and Dassault Aviation. The SBJ project was unveiled at the 2004 NBAA convention, backed by US billionaire Robert Bass, with introduction targeted at 2011 for a $1.2–1.4 billion development cost, anticipating a 250–300 aircraft civil market over 10 years. Aerion then planned wind tunnel testing i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concorde
The Aérospatiale/BAC Concorde () is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation (later Aérospatiale) 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 (£ in ). 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. Concorde is a tailless aircraft design with a narrow fuselage permitting a 4-abreast seating for 92 to 128 passengers, an ogival delta wing and a droop nose for landing visibility. It is powered by four Rolls-Royce/Snecma Olympus 593 turbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airline
An airline is a company that provides civil aviation, air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or Airline alliance, alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an Air operator's certificate, air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or Air charter, charter operators. The List of airlines by foundation date, first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Czech Republic's Czech Airlines (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to ...

Jet Airliner
A jet airliner or jetliner is an airliner powered by jet engines (passenger jet aircraft). Airliners usually have two or four jet engines; three-engined designs were popular in the 1970s but are less common today. Airliners are commonly classified as either the large wide-body aircraft A wide-body aircraft, also known as a twin-aisle aircraft, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is . In the typical wide-body economy cabi ..., medium narrow-body aircraft and smaller regional jet. Most airliners today are powered by jet engines, because they are capable of safely operating at high speeds and generate sufficient thrust to power large-capacity aircraft. The first jetliners, introduced in the 1950s, used the simpler turbojet engine; these were quickly supplanted by designs using turbofans, which are quieter and more fuel-efficient.

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonic Boom
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 decibel is the primary unit measurement of sound. "A thunderclap is incredibly loud, producing levels between 100 and 120 dBA (Decibel, decibels A)- the equivalent of standing near a jet during take-off." The crack of a supersonic bullet passing overhead or the crack of a bullwhip are examples of a sonic boom in miniature. 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 prohibition of routine supersonic flight overland. Although they cannot be completely prevented, research suggests that with careful shaping of the vehicle, the nuisance due to the sonic booms may be reduced to the point that overland super ...

Supercruise
Supercruise is sustained supersonic flight of a supersonic aircraft with a useful cargo, passenger, or weapons load without using afterburner (also known as "reheat"). Many supersonic military aircraft are not capable of supercruise and can only maintain Mach 1+ flight in short bursts with afterburners. Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some 4th generation fighter jets are technically capable of supercruise, but only at high altitudes and in a clean configuration. For an aircraft to be deemed capable of true supercruise, it must be able to carry a normal load for an extended distance without diving or using an afterburner. Planes marketed as featuring supercruise usually have the ability to carry a combat load at low to medium altitudes; being able to break Mach 1 without afterburner does not necessarily show supercruise ability. For example, the Federation of American Scientists defined supercruise as "the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
