Project 921-3
Project 921-3 is a crewed spacecraft sub-system of Project 921. The term 921-3 is often used for the Chinese spaceplane program. History The Chinese National Manned Space Program was given the designation of Project 921 in 1992. This broad project was divided into three phases: 921-1 to launch a crewed mission by 2002 in a craft that became the Shenzhou, the Project 921-2 temporary space station by 2010, and the 921-3 permanent space station by 2020. Care must be taken not to confuse the three phases of Project 921 with its seven sub-systems (921-1, 921-2 ... 921-7). Early planning of Project 921 included six different proposals for a crewed space transportation system. Five of these proposals were of a space-Earth transportation system using a delta winged orbiter. By 1990, the proposal for the Soyuz-like capsule Shenzhou had won out. Some small models for a spaceplane were made public, but the concept was rejected in favor of a Soyuz-like capsule which became Shenzho ...

Project 921
The China Manned Space Program (CMS; ), also known as Project 921 () is a space program developed by the People's Republic of China and run by the China Manned Space Agency (CMSA), designed to develop and enhance human spaceflight capabilities for China. It was approved on 21 September 1992 and has been in operation ever since. The ''CMS'' director is currently Zhou Jianping; he has held this position since 2006, after taking over from Wang Yongzhi, who served as the first director from 1992 to 2006. As one of the most complex programs within the Chinese space agency, CMS was split into "three steps", or three phases, which can be summarized as follows: # Crewed spacecraft launch and return. # Space laboratory (with capabilities of extravehicular activities), spacecraft rendezvous and docking procedures. # Long term modular space station. On 29 November 2022, with the launch and docking of ''Shenzhou 15'' with the Tiangong space station, the CMSA successfully completed all thre ...

High-temperature Superconductivity
High-temperature superconductors (abbreviated high-c or HTS) are defined as materials that behave as superconductors at temperatures above , the boiling point of liquid nitrogen. The adjective "high temperature" is only in respect to previously known superconductors, which function at even colder temperatures close to absolute zero. In absolute terms, these "high temperatures" are still far below ambient, and therefore require cooling. The first high-temperature superconductor was discovered in 1986, by IBM researchers Bednorz and Müller, who were awarded the Nobel Prize in Physics in 1987 "for their important break-through in the discovery of superconductivity in ceramic materials". Most high-c materials are type-II superconductors. The major advantage of high-temperature superconductors is that they can be cooled by using liquid nitrogen, as opposed to the previously known superconductors which require expensive and hard-to-handle coolants, primarily liquid helium. ...

Crewed Spacecraft
This is a list of all crewed spacecraft types that have flown into space, including sub-orbital flights above 80 km, Space Stations that have been visited by at least one crew, and spacecraft currently planned to operate with crew in the future. It does not contain spacecraft that have only flown un-crewed and have retired from service, even if they were designed for crewed flight, such as Buran, or crewed flights by spacecraft below 80 km. There is some debate concerning the height at which space is reached (the Karman Line), the Fédération Aéronautique Internationale (FAI) recognise 100 km, NASA, and the USAF recognise this as 50 miles (approx 80 km) - this article choses the latter, to include the widest possible definition. Since the first crewed spaceflight of Vostok 1 in 1961 there have been 13 types of spacecraft that have made crewed flights into space - nine American, three Russian, and one Chinese. There are currently five operational crewed s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NASA X-43
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program. It set several airspeed records for jet aircraft. The X-43 is the fastest jet-powered aircraft on record at approximately Mach 9.6.Thompson, Elvia, Keith Henry and Leslie Williams"Faster Than a Speeding Bullet: Guinness Recognizes NASA Scramjet."''NASA.'' Retrieved: August 1, 2011. A winged booster rocket with the X-43 placed on top, called a "stack", was drop launched from a Boeing B-52 Stratofortress. After the booster rocket (a modified first stage of the Pegasus rocket) brought the stack to the target speed and altitude, it was discarded, and the X-43 flew free using its own engine, a scramjet. The first plane in the series, the X-43A, was a single-use vehicle, of which three were built. The first X-43A was destroyed after malfunctioning in ...

Eleventh Five-Year Plan (People's Republic Of China)
The Five-Year Plans () are a series of social and economic development initiatives issued by the Chinese Communist Party (CCP) since 1953 in the People's Republic of China. Since 1949, the CCP has shaped the Chinese economy through the plenums of its Central Committee and national congresses. The party plays a leading role in establishing the foundations and principles of Chinese communism, mapping strategies for economic development, setting growth targets, and launching reforms. Planning is a key characteristic of the nominally socialist economies, and one plan established for the entire country normally contains detailed economic development guidelines for all its regions. In order to more accurately reflect China's transition from a Soviet-style command economy to a socialist market economy (socialism with Chinese characteristics), the plans since the 11th Five-Year Plan for 2006 to 2010 have been referred to in Chinese as "guidelines" () instead of as "plans" ().

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Standard Mandarin
Standard Chinese ()—in linguistics Standard Northern Mandarin or Standard Beijing Mandarin, in common speech simply Mandarin, better qualified as Standard Mandarin, Modern Standard Mandarin or Standard Mandarin Chinese—is a modern standardized form of Mandarin Chinese that was first developed during the Republican Era (1912‒1949). It is designated as the official language of mainland China and a major language in the United Nations, Singapore, and Taiwan. It is largely based on the Beijing dialect. Standard Chinese is a pluricentric language with local standards in mainland China, Taiwan and Singapore that mainly differ in their lexicon. Hong Kong written Chinese, used for formal written communication in Hong Kong and Macau, is a form of Standard Chinese that is read aloud with the Cantonese reading of characters. Like other Sinitic languages, Standard Chinese is a tonal language with topic-prominent organization and subject–verb–object (SVO) word order. Compar ...
