36th Air Division (People's Republic Of China)
The 36th Bomber Division or 36th Air Division (, 36th AD) of the People's Liberation Army Air Force (PLAAF) is an air formation of the People's Republic of China (PRC). The 36th Bomber Division is one of only three bomber divisions in the PLAAF and is presently assigned to the Central Theater Command Air Force. History The 36th Bomber Division began as the PLAAF's 4th Independent Regiment reorganized from the 28th Air Regiment of the 10th Bomber Division (today assigned to the Eastern Theater Command Air Force) on 15 March 1953. The 4th Independent Regiment originally operated the Soviet-gifted Tupolev Tu-4 bombers, becoming the PLAAF's first heavy bomber unit. A year later in March 1954, the unit was relocated to Nanyuan Air Base (China's oldest airfield dating back to the Qing Dynasty) near Beijing until March 1955 when it was again moved to Wugong, Shaanxi, joining the Northwest Military Region Air Force (later Lanzhou). Although it is unclear why the regiment would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Lanzhou Military Region
The Lanzhou Military Region was one of seven military regions in the People's Republic of China. It directed all People's Liberation Army and People's Armed Police forces in Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi, and Ngari Prefecture in northwest Tibet. It was headquartered in Lanzhou in Gansu Province. It is bordered to the south by the Chengdu Military Region, and to the north by Mongolia, the Altai Republic, which is a political subdivision of the Russian Federation, and Kazakhstan. This region is now part of the Western Theater Command due to the military reforms of 2015. In 2006 the International Institute for Strategic Studies attributed the Region with an estimated 220,000 personnel, a single armoured division, two motorised infantry divisions, one artillery division, one armoured, two motorised infantry, one artillery, one anti-aircraft brigades plus a single anti-tank regiment.

Dong Fang Hong 1
''Dong Fang Hong 1'' (), in the western world also known as China 1 or PRC 1, was the first space satellite of the People's Republic of China (PRC), launched successfully on 24 April 1970 as part of the PRC's Dongfanghong space satellite program. It was a part of the "Two Bombs, One Satellite" program. At , it was heavier than the first satellites of other countries. The satellite carried a radio transmitter which broadcast the ''de facto'' national anthem of the same name. The broadcast lasted for 20 days while in orbit. It was developed under the direction of Qian Xuesen, dean of the China Academy of Space Technology (CAST). At the time, a total of five identical satellites were created. The first satellite launched successfully. The academy formulated a "Three-Satellite Plan" consisting of ''Dongfanghong 1'', re-entry satellites, and geosynchronous orbit communications satellites. Sun Jiadong was responsible for the ''Dongfanghong 1'' technology. In 1967, Dang Hongxin chos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio Broadcast relay station, relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two Bombs, One Satellite
Two Bombs, One Satellite () was an early nuclear and space project of the People's Republic of China. ''Two Bombs'' refers to the atomic bomb (and later the hydrogen bomb) and the intercontinental ballistic missile (ICBM), while ''One Satellite'' refers to the artificial satellite. China tested its first atomic bomb and first hydrogen bomb in 1964 and 1967 respectively, combining the atomic bomb with surface-to-surface missile in 1966, and successfully launched its first satellite (Dong Fang Hong I) in 1970. History Proposal and Soviet aid In the 1940s and 50s, a group of notable scientists including Qian Weichang, Qian Xuesen, Deng Jiaxian, Peng Huanwu and Qian Sanqiang returned to mainland China. In January 1955, Mao Zedong expressed the intention of developing atomic bombs during a meeting of the Secretariat of the Chinese Communist Party. In 1956, hundreds of experts were called by Zhou Enlai, Chen Yi, Li Fuchun and Nie Rongzhen to make plans for China's scientific ...

Nuclear Weapon Design
Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types: * pure fission weapons, the simplest and least technically demanding, were the first nuclear weapons built and have so far been the only type ever used in warfare (by the United States on Empire of Japan, Japan during World War II, WWII). * boosted fission weapons increase yield beyond that of the implosion design by using small quantities of fusion fuel to enhance the fission chain reaction. Boosting can more than double the weapon's fission energy yield. * thermonuclear weapon, staged thermonuclear weapons are essentially arrangements of two or more "stages", most usually two. The first stage is normally a boosted fission weapon as above (except for the earliest thermonuclear weapons, which used a pure fission weapon instead). Its detonation causes it to shine intensely with x-radiation, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium-235
Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about 584.3±1 barns. For fast neutrons it is on the order of 1 barn. Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-236. Natural decay chain :\begin \ce \begin \ce \\ \ce \end \ce \\ \ce \begin \ce \\ \ce \end \ce \end Fission properties The fission of one atom of uranium-235 releases () inside the reactor. That corresponds to 19.54 TJ/ mol, or 83.14 TJ/kg. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project 596
Project 596, (Miss Qiu ( zh, 邱小姐, Qiū Xiǎojiě) as the callsign, Chic-1 by the US intelligence agencies) was the first nuclear weapons test conducted by the People's Republic of China, detonated on 16 October 1964, at the Lop Nur test site. It was a uranium-235 implosion fission device made from weapons-grade uranium (U-235) enriched in a gaseous diffusion plant in Lanzhou.10.1177/0967010696027001006 ISSNbr>0967-0106 Development Motivation The Chinese nuclear weapons program was initiated on 15 January 1955. The decision made by the Chinese leadership was prompted by confrontations with the United States in the 1950s, including the Korean War, the 1955 Taiwan Straits Crisis, nuclear blackmail, and eventually the Vietnam War as well.

Aerial Survey
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected include aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and also geophysical data (such as aeromagnetic surveys and gravity. It can also refer to the chart or map made by analysing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality and atmospheric conditions (which can negatively impact and obscure satellite observation). Today, aerial survey is sometimes recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods. Aerial surveys can provide information on many things not vis ...
