Lockheed MQM-105 Aquila
The Lockheed MQM-105 Aquila (Eagle) was the first small battlefield drone developed in the United States during the 1970s to act as a target designator for the US Army. Early history The modern history of the Army's battlefield drone efforts began in 1972, when DARPA began the Remotely Piloted Aerial Observation/Designation System program which included PRAIRIE, Calare, and Aequare. The program was conceptualized in January 1973 in the joint U.S. Army and DARPA-funded project called RPAODS (''Remotely Piloted Aerial Observer Designator System''). PRAIRIE was a Philco Ford UAV with a TV camera and a laser target designator. PRAIRIE was able to target a truck and guide a laser-guided bomb to it. Calare and Aequare was delivered by Melpar and JHU/APL respectively. Melpar's prototype was launched from the top of the truck and landed on skids on a prepared runway. APL's prototype was a delta-wing aircraft, launched from a small cart and assisted by a bungee cord DARPA does no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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".

Dornier GmbH
Dornier Flugzeugwerke was a German aircraft manufacturer founded in Friedrichshafen in 1914 by Claude Dornier. Over the course of its long lifespan, the company produced many designs for both the civil and military markets. History Originally Dornier Metallbau, Dornier Flugzeugwerke took over Flugzeugbau Friedrichshafen production facilities ( Weingarten, Warnemünde, and the former Zeppelin shed at Manzell) when it failed in 1923. Dornier was well known between the two world wars as a manufacturer of large, all-metal flying boats and of land based airliners. The record-breaking 1924 Wal () was used on many long distance flights and the Do X set records for its immense size and weight. Dornier's successful landplane airliners, including the Komet (''Comet'') and Merkur (''Mercury''), were used by Lufthansa and other European carriers during the 1920s and early 30s. Dornier built its aircraft outside Germany during much of this period due to the restrictions placed on Germa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailless Aircraft
In aeronautics, a tailless aircraft is a fixed-wing aircraft with no other horizontal aerodynamic surface besides its main wing. It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim. Tailless aircraft have been flown since the pioneer days; the first stable aeroplane to fly was the tailless Dunne D.5, in 1910. The most successful tailless configuration has been the tailless delta, especially for combat aircraft, though the Concorde airliner is also a delta configuration. NASA has used the 'tailless' description for the novel X-36 research aircraft which has a canard foreplane but no vertical fin. Aircraft configuration A tailless aircraft has no other horizontal surface besides its main wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blended Wing Body
A blended wing body (BWB), also known as blended body, hybrid wing body (HWB) or a lifting aerofoil fuselage, is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line.Crane, Dale. ''Dictionary of Aeronautical Terms, third edition''. Newcastle, Washington: Aviation Supplies & Academics, 1997. . p. 224. This contrasts with a flying wing, which has no distinct fuselage, and a lifting body, which has no distinct wings. A BWB design may or may not be tailless aircraft, tailless. The main advantage of the BWB is to reduce wetted area and the accompanying form drag associated with a conventional wing-body junction. It may also be given a wide airfoil-shaped body, allowing the entire craft to generate lift (force), lift and thus reducing the size and drag of the wings. The BWB configuration is used for both aircraft and underw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicles Of The United States
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. It has been reported that the armed forces of more than 100 countries have approximately 170 different types of drones in service. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) **Self-driving truck **Driverless tractor * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft, either fixed-wing or rotorwing, commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium ...

1980s United States Special-purpose Aircraft
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 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.

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...

Operation Mole Cricket 19
Operation Mole Cricket 19 () was a suppression of enemy air defenses (SEAD) campaign launched by the Israeli Air Force (IAF) against Syrian targets on June 9, 1982, at the outset of the 1982 Lebanon War. The operation was the first time in history that a Western-equipped air force successfully destroyed a Soviet-built surface-to-air missile (SAM) network. It also became one of the biggest air battles since World War II,Nordeen (1990), p. 175 and the biggest since the Korean War.Cohen (1990), p. 615 The result was a decisive Israeli victory. The IAF began working on a SAM suppression operation at the end of the Yom Kippur War. Rising tensions between Israel and Syria over Lebanon escalated in the early 1980s and culminated in Syria deploying SAM batteries in the Beqaa Valley. On June 6, 1982, Israel invaded Lebanon, and on the third day of the war, with clashes ongoing between the Israel Defense Forces (IDF) and the Syrian Army, Israel decided to launch the operation.

Israeli Air Force
The Israeli Air Force (IAF; , commonly known as , ''Kheil HaAvir'', "Air Corps") operates as the aerial and space warfare branch of the Israel Defense Forces (IDF). It was founded on May 28, 1948, shortly after the Israeli Declaration of Independence. , Aluf Tomer Bar has been serving as the Air Force commander. The Israeli Air Force was established using commandeered or donated civilian aircraft and obsolete and surplus World War II combat aircraft. Eventually, more aircraft were procured, including Boeing B-17s, Bristol Beaufighters, de Havilland Mosquitoes and P-51D Mustangs. The Israeli Air Force played an important part in Operation Kadesh, Israel's part in the 1956 Suez Crisis, dropping paratroopers at the Mitla Pass. On June 5, 1967, the first day of the Six-Day War, the Israeli Air Force performed Operation Focus, debilitating the opposing Arab air forces and attaining air supremacy for the remainder of the war.
