ChangKong-1
The NAI CK-1 () is a target drone, and the first drone, developed by the People's Republic of China. It was derived from the Soviet Lavochkin La-17 unmanned aerial vehicle (UAV). Development started with the People's Liberation Army Air Force (PLAAF) in the early-1960s before being taken over by the Nanjing Aviation Institute (NAI) in 1968. It entered service in the late-1970s. Development The PLAAF used Soviet-supplied La-17s for training since the late-1950s. China decided to reverse engineer and produce the UAV as the CK-1 when the Sino-Soviet split ended further supply. Development began in the early-1960s at the PLAAF's Weapon Test and Training Base under General Zhao Xu ("the father of the Chinese UAV".) Work was halted by the Cultural Revolution, and resumed in April 1967 at NAI. The first test launch occurred in late-1969, possible in October or 6 December, with trials completing in 1976. The drone entered the PLAAF's inventory in March 1977 but may not have rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavochkin La-17
The Lavochkin La-17 was the first Soviet Union, Soviet unmanned aerial vehicle (UAV) to reach operational service. The first versions were developed in the early 1950s, and remained in service into the 1980s. Early development The La-17 was designed by the Lavochkin design bureau, with work beginning in 1950. Flight tests began in 1953, with prototype drones carried on a Tupolev Tu-4 four-engine bomber. La-17 production began in 1956. The La-17 was a jet drone of all-metal construction, with straight flight surfaces, and a jet engine carried in a nacelle under the fuselage. The initial variant, which was just known as the "La-17", was air-launched. and powered by a Bondaryuk RD-900 ramjet with 800 kgf (1,760 lbf) thrust. There was a "windmill" type electric generator in the nose, somewhat along the lines of the WW II-era Luftwaffe's Me 163 manned rocket interceptor to provide electric power. The La-17 was directed by radio control and simply "bellied in" to land, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Autopilot
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"''). The etymology of the nickname is unclear: some claim it is a reference to inventor George De Beeson, who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to King George VI. First autopilots In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1960s Chinese Military Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

List Of Unmanned Aerial Vehicles Of The People's Republic Of China
This is a list of unmanned aerial vehicles (UAVs, or 'drones'), of China. There are further categories and sub-categories following the main, comprehensive list, and some of the UAVs appear in more than one category/ sub-category when they can be classified by more than one. As late of 2010, there are more than a hundred UAV developers/manufacturers currently in China. By 2014, that number is increased to over two hundred thirty UAV developers / manufacturers in China, with over two-thirds of them are private enterprises (PE), and the remaining are government-owned enterprises. Most of the government-owned enterprises are fully capable of indigenously completing the entire development of UAVs of various sizes, from the initial design at the very beginning, all the way to the final completion of UAVs of various sizes, ranging from the smallest micro air vehicle (MAV)s to the largest UAVs. In contrast, most private enterprises lack such capability because they are assemblers purch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryan Firebee
The Ryan Firebee is a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and remains one of the most widely used target drones ever built. Development Ryan Firebee I Q-2/KDA-1 Firebee The Firebee I was the result of a 1948 U.S. Air Force request and contract to Ryan for a jet-powered gunnery target. The first flight of the XQ-2 Firebee prototype took place in early 1951. The drone featured swept flight surfaces and a circular nose inlet. The initial models had distinctive "arrowhead" shaped endplates on the tailplane. The Firebee could be air-launched from a specially modified launch aircraft (Douglas A-26 Invader was first to be used for this), or ground-launched with a single RATO booster. Following successful evaluation the target was ordered into production for the USAF as the Q-2A, powered by a Continental J69-T-19B turbojet engine with of thrust. The Air Force then obtained small number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruise Missile
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the American aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control. Inspired by the experiments, the United States Army developed a similar flying bomb cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Signature
Infrared signature, as used by defense scientists and the military, is the appearance of objects to infrared sensors. An infrared signature depends on many factors, including the shape and size of the object, temperature, and emissivity, reflection of external sources (earthshine, sunshine, skyshine) from the object's surface, the background against which it is viewed and the waveband of the detecting sensor. As such there is no all-encompassing definition of infrared signature nor any trivial means of measuring it. For example, the infrared signature of a truck viewed against a field will vary significantly with changing weather, time of day and engine loading. Two fairly successful examples of defining the infrared signature of an object are the apparent temperature difference at the sensor and the contrast radiant intensity (CRI) definitions. Apparent temperature difference The apparent temperature difference method of defining infrared signature gives the physical temperature ...

G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
