Test Article (aerospace)
A test article or pathfinder is a version of a spacecraft or related vehicle or equipment, built as a platform to perform testing on particular portions of a spaceflight regime. Test articles are built to the specifications necessary to replicate particular conditions and behaviors that are to be validated. Test articles may be built for flight testing or for non-flight testing. For space agencies with extensive flight certification procedures, they may be built without the certification and quality control steps taken with the versions intended for flight. Test articles are more complete than a boilerplate. Overview Some test articles are theoretically able to be modified and upgraded to flight-ready status. Of the 136 Space Shuttle external fuel tanks produced, one was retained as a test article. The contractor producing the tanks stated that that tank could be refurbished for flight use if necessary. Test articles are often displayed in museums because of their accurac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. In specialised domains such as scientific research, navigation, and timekeeping, other standards such as Universal Time, UT1 and International Atomic Time (TAI) are also used alongside UTC. UTC is based on TAI (International Atomic Time, abbreviated from its French name, ''temps atomique international''), which is a weighted average of hundreds of atomic clocks worldwide. UTC is within about one second of mean solar time at 0° longitude, the currently used prime meridian, and is not adjusted for daylight saving time. The coordination of t ...

Grid Fin
Grid fins (or lattice fins) are a type of flight control surfaces, flight control surface used on rockets and bombs, sometimes in place of more conventional control surfaces, such as planar fins. They were developed in the 1950s by a team led by and used since the 1970s in various Soviet Union, Soviet ballistic missile designs such as the SS-12 Scaleboard, SS-12 ''Scaleboard'', SS-20, SS-20 ''Saber'', OTR-21 Tochka, SS-21 ''Scarab'', SS-23, SS-23 ''Spider'', and SS-25, SS-25 ''Sickle'', as well as the N1 rocket, N-1 (the intended rocket for the Soviet Moonshot, Soviet moon program). In Russia, they are thus often referred to as ' grid fins. Grid fins have also been used on conventional missiles and bombs such as the Vympel R-77 air-to-air missile; the 3M-54 Klub (SS-N-27 Sizzler) family of cruise missiles; and the American GBU-43 Massive Ordnance Air Blast bomb, Massive Ordnance Air Blast (MOAB) large-yield conventional bomb, and on specialized devices such as the RQ-7 Shadow#Qui ...

DF-15
The Dong-Feng 15 (a.k.a. DF-15, M-9, CSS-6) is a short-range ballistic missile developed by China. The U.S. Department of Defense estimated in 2008 that China had 315–355 DF-15 missiles and 90–110 launchers. History Development on the DF-15 began in 1985 with a finalized design proposal being approved by the PLA in 1987. From the late 1980s to the mid-1990s, testing of the missile was done in the Gobi Desert. The first public display of the missile took place at the Beijing Defense Exposition in 1986. The Second Artillery Corps had allegedly deployed a small number of the missiles the following year. In 1989, Libya agreed to finance Syria's purchase of M-9 missiles from China. The sale of missiles to Syria were cancelled under U.S. pressure in 1991. Description The DF-15 uses a solid fuel, single-stage rocket. It is vertically launched from an eight-wheeled transporter erector launcher (TEL). The missile's trajectory is guided using small thrusters and an inertial gu ...

DF-11
The Dong-Feng 11 (a.k.a. M-11, CSS-7) is a short-range ballistic missile developed by the People's Republic of China. History The DF-11 is a road-mobile short-range ballistic missile (SRBM) which began development in 1984 as the M-11, of which was led by the China Sanjiang Space Group (previously known as Base 066). It entered service with the People's Liberation Army, PLA Second Artillery Corps in 1992. In 1993, Pakistan purchased the weapon system in secrecy from China but M-11 are capable of delivering conventional ammunition not nuclear capable. Description The DF-11 has range of 300 km with an 800 kg payload. An improved DF-11A version has increased range of >825 km. The range of the M-11 does not violate the limits set by the Missile Technology Control Regime (MTCR). Unlike previous Chinese ballistic missiles, the DF-11 use solid fuel, which greatly reduces launch preparation time (15-30 min). liquid fuel, Liquid-fueled missiles such as the DF-5 requir ...

Gobi Desert
The Gobi Desert (, , ; ) is a large, cold desert and grassland region in North China and southern Mongolia. It is the sixth-largest desert in the world. The name of the desert comes from the Mongolian word ''gobi'', used to refer to all of the waterless regions in the Mongolian Plateau; in Chinese, ''gobi'' is used to refer to rocky, semi-deserts such as the Gobi itself rather than sandy deserts. Geography The Gobi measures from southwest to northeast and from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). Its area is approximately . Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116–118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Pla ...

Sub-orbital Spaceflight
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the primary (astronomy), gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity. For example, the path of an object launched from Earth that reaches the Kármán line (about – above sea level), and then falls back to Earth, is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the North American X-15, X-15 and SpaceShipTwo, and uncrewed ones, such as intercontinental ballistic missile, ICBMs and sounding rockets. Flights which attain sufficient velocity to go into low Earth orbit, and then de-orbit before com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
