Boeing E-767
The Boeing E-767 is an Airborne Warning and Control System (AWACS) aircraft that was designed in response to the Japan Air Self-Defense Force's requirements. It is essentially the Boeing E-3 Sentry's surveillance radar and air control system installed on a Boeing 767-200. Development Background On September 6, 1976, Soviet Air Forces pilot Viktor Belenko successfully defected to the West, flying his MiG-25 'Foxbat' to Hakodate, Japan. During this incident, Japan Self-Defense Force radar lost track of the aircraft when Belenko flew his MiG-25 at a low altitude, prompting the Japan Air Self-Defense Force (JASDF) to consider procurement of airborne early warning aircraft. In 1976, the U.S. Air Force was about to deploy the E-3 Sentry airborne warning and control system aircraft, which was considered to be the prime candidate for the airborne early warning mission by JASDF. However, the Japan Defense Agency (JDA, now Ministry of Defense) realized that the E-3 would not be read ... [...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 Wikimedia project, 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 Magazine, 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organization ...

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromag ...

Joint Tactical Information Distribution System
The Joint Tactical Information Distribution System (JTIDS) is an L band Distributed Time Division Multiple Access (DTDMA) network radio system used by the United States armed forces and their allies to support data communications needs, principally in the air and missile defense community. It produces a spread spectrum signal using Frequency-shift keying (FSK) and Phase-shift keying (PSK) to spread the radiated power over a wider spectrum (range of frequencies) than normal radio transmissions. This reduces susceptibility to noise, jamming, and interception. In JTIDS Time Division Multiple Access (TDMA) (similar to cell phone technology), each time interval (e.g., 1 second) is divided into time slots (e.g. 128 per second). Together, all 1536 time slots in a 12-second interval are called a "frame". Each time slot is "bursted" (transmitted) at several different carrier frequencies sequentially. Within each slot, the phase angle of the transmission burst is varied to provide PSK. Each t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conductors can radiate into space as electromagnetic waves ( radio waves). This is the basis of radio technology. * RF current does not penetrate deeply into ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small ...

List Of Boeing Customer Codes
Unique, fixed customer codes were used by Boeing Commercial Airplanes to denote the original customer for airframes produced as part of Boeing's 7x7 family of commercial aircraft from 1956 (except for the Boeing 787 Dreamliner), starting with the introduction of the 707, followed by the Boeing 717, Boeing 727, Boeing 737, Boeing 747, Boeing 757, Boeing 767 and Boeing 777 up until 2016. The codes are in the form of two letters and/or digits which are appended to the aircraft's model designator, as seen in the following examples: *A Boeing 707-100 ordered by Qantas with customer code 38 would be designated as 707-138. *A Boeing 717 ordered by Hawaiian Airlines with customer code 2A would be designated as 717-22A. *A Boeing 727-100 and 727-200 ordered by United Airlines with customer code 22 are designated as 727-022 (not -122) and 727-222 respectively. *A Boeing 737-700 and 737-800 ordered by Southwest Airlines with customer code H4 would be designated as 737-7H4 and 737-8H4 r ...

Foreign Military Sales
The United States Department of Defense's Foreign Military Sales (FMS) program facilitates sales of U.S. arms, defense equipment, defense services, and military training to foreign governments. The purchaser does not deal directly with the defense contractor; instead, the Defense Security Cooperation Agency (DSCA) serves as an intermediary, usually handling procurement, logistics, and delivery, often providing product support, training, and infrastructure construction (such as hangars, runways, utilities, etc.). FMS is carried out with countries that are authorized to participate and is subject to approval based on the mechanism to procure services, a deposit in a U.S. trust fund or appropriate credit, and approval to fund services. On any given day, DSCA is managing “14,000 open foreign military sales cases with 185 countries,” the DSCA director Lieutenant General Charles Hooper explained at the Brookings Institution in June 2019. Some U.S. Air Force (USAF) FMS programs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
