Teledyne CAE J402
The Teledyne CAE J402 is a small turbojet engine. Several variants have been developed to power unmanned air vehicles such as missiles and target drones. Developed in the 1970s for the Harpoon anti-ship missile, the J402 was the first jet engine to be designed as a " wooden round", meaning that the engine had to be able to sit for long periods without maintenance or inspection and work right away. Development and design The J402 engine was designed for the Harpoon missile from the beginning. Its size and weight were dictated by the already-planned missile (just over 12 inches (30 cm) in diameter, about 100 lb (45 kg) in weight). The engine also had to be designed to be inexpensive; the military wanted to produce and store large quantities of the missile. To meet these requirements, Teledyne aerodynamically scaled their J69-T-406 turbojet to just 32% air capacity. This brought thrust and size down to the desired levels. The J402-CA-400, the original Harpoon va ... [...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".

Centrifugal Compressor
Centrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. The following equation shows this specific energy input. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The static pressure rise in the impeller may roughly equal the rise in the diffuser. Equation-0.1 : H = \left( \left( R \right)_2 - \left( R \right)_1 \right) :where the control volume nomenclature (illustrated in Figure-0.4) is: ::* subscript, is the impeller inlet location, station1 ::* subscript, is the impeller discharge/exit location, station2 ::* is the energy input per unit mass, units=(LP/m) ::* is the impeller's rotation speed, units=(radians/t) ::* is the radius of specified location, units=(L) ::* is ve ...

1970s Turbojet Engines
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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.

AGM-84H/K SLAM-ER
The AGM-84H/K SLAM-ER (Standoff Land Attack Missile-Expanded Response) is an advanced stand off precision-guided, air-launched cruise missile produced by Boeing Defense, Space & Security for the United States Armed Forces and their allies. Developed from the AGM-84E SLAM (Standoff Land Attack Missile, itself developed by Boeing Integrated Defense Systems from the McDonnell Douglas Harpoon antiship missile), the SLAM-ER is capable of attacking land and sea targets medium to long range (over 155 nautical miles/270 km maximum). The SLAM-ER relies on the Global Positioning System (GPS) and infrared imaging for its navigation and control, and it can strike both moving and stationary targets. The SLAM-ER can be remotely controlled while in flight, and it can be redirected to another target after launch if the original target has already been destroyed, or is no longer considered to be dangerous ( command guidance). The SLAM-ER is a very accurate weapon; as of 2009 it had the bes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-84E Standoff Land Attack Missile
The AGM-84E SLAM (Standoff Land Attack Missile) was a subsonic, over-the-horizon air-launched cruise missile that was developed by McDonnell Douglas from the AGM-84 Harpoon antiship missile. The SLAM was designed to provide all-weather, day and night, precision attack capabilities against stationary high-value targets as well as ships in port. Design Except for new technologies in the guidance and seeker sections, which included a Global Positioning System receiver, a modified AGM-65F Maverick missile IIR Seeker, and a modified Walleye datalink, all of the missile hardware came directly from the Harpoon missile. SLAM missile uses an inertial navigation system, which is supplemented by Global Positioning System (GPS) input, and it also uses infrared homing terminal guidance. It could also be guided by any aircraft carrying the AN/AWW-9B and AN/AWW-13 datalink pods. The missile however was unable to avoid terrain, meaning that to attack a target, there had to be no obstacles in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Specific Fuel Consumption
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence ''thrust-specific''. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed. TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel measure, since it is independent of temperature. Specific fuel consumption of air-breathing jet engines at their maximum efficiency is more or less proportional to exhaust speed. The fuel consumption ''per mile'' or ''per kilometre'' is a more appropriate comparison for aircraft that travel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrotechnics
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words ''pyr'' ("fire") and ''tekhnikos'' ("made by art"). People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximate ...

Combustor
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the ''combustor'' or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and c ...
