Supersonic Airliner
file:concorde.highup.arp.750pix.jpg, The Concorde supersonic transport had an ogive, ogival delta wing, a slender fuselage and four underslung Rolls-Royce/Snecma Olympus 593 engines. file:Tu-144.jpg, The Tupolev Tu-144 was the first SST to enter service and the first to leave it. Only 55 passenger flights were carried out before service ended due to safety concerns. A small number of cargo and test flights were also carried out after its retirement. A supersonic transport (SST) or a supersonic airliner is a Civil aviation, 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. 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 flying, ferry flight being its last flight. Following the terminatio ...

Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airliner
An airliner is a type of airplane for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a long, tube shaped, and jet powered aircraft. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major carriers, legacy carriers, and flag carriers, and are used to feed traffic into the large a ...

South China Morning Post
The ''South China Morning Post'' (''SCMP''), with its Sunday edition, the ''Sunday Morning Post'', is a Hong Kong-based English-language newspaper owned by Alibaba Group. Founded in 1903 by Tse Tsan-tai and Alfred Cunningham, it has remained Hong Kong's newspaper of record since British colonial rule. Editor-in-chief Tammy Tam succeeded Wang Xiangwei in 2016. The ''SCMP'' prints paper editions in Hong Kong and operates an online news website that is blocked in mainland China. The newspaper's circulation has been relatively stable for years—the average daily circulation stood at 100,000 in 2016. In a 2019 survey by the Chinese University of Hong Kong, the ''SCMP'' was regarded relatively as the most credible paid newspaper in Hong Kong. The ''SCMP'' was owned by Rupert Murdoch's News Corporation from 1986 until it was acquired by Malaysian real estate tycoon Robert Kuok in 1993. On 5 April 2016, Alibaba Group acquired the media properties of the SCMP Group, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boom Overture
The Boom Overture is a supersonic airliner under development by Boom Technology, designed to cruise at Mach 1.7 or . It is expected to carry 64 to 80 passengers, depending on configuration, with a range of . Boom aims to introduce the Overture in 2029. The company projects a market for up to 1,000 supersonic aircraft serving 500 viable routes, with fares comparable to business class. Featuring a delta wing design similar to that of the Concorde, the Overture is expected to use composite materials in its construction. A 2022 redesign specified four dry (non-afterburning) turbofan engines, each reportedly producing of thrust. Market According to the company, up to 500 daily routes could be viable. At Mach 1.7 over water, transatlantic flight times would be reduced significantly: Newark to London in 3 hours 30 minutes, and Newark and Frankfurt in 4 hours. With a range of , transpacific flights would require a refueling stop, meaning a trip between San Francisco and To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
