Lockheed Martin RQ-170 Sentinel
The Lockheed Martin RQ-170 Sentinel, nicknamed Wraith, is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF) for the Central Intelligence Agency (CIA). While the USAF has released few details on the UAV's design or capabilities, defense analysts believe that it is a stealth aircraft fitted with aerial reconnaissance equipment. Introduced in 2007, it was deployed to Afghanistan in late 2007, and to South Korea two years later, in September 2009. Some images and details of the aircraft were released after Iran–U.S. RQ-170 incident, Iran captured an RQ-170 in 2011. It has a flying wing design, and uses a single engine, speculated to be either a General Electric TF34 turbofan or a Garrett TFE731. Development The RQ-170 Sentinel was developed by Lockheed Martin's Skunk Works as a Stealth aircraft, stealth unmanned aerial vehicle (UAV). Journalists have noted design similarities between the RQ-170 and previous ... [...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".

Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology. Other examples of stealth aircraft include the Northrop Grumman B-2 Spirit, B-2 Spirit, the B-21 Raider, the Lockheed Martin F-22 Raptor, F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is completely invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft avoiding detection by enemy radar and/or avoiding being successfully targeted by Semi-active radar guidance, radar guided weapons. Stealth is a combination of passive low observable (LO) features and active emitters such as low-probability-of-interc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zigzag
A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular. In geometry, this pattern is described as a Infinite skew polygon, skew apeirogon. From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection. Although the origin of the word is unclear, its first printed appearances were in French-language books and ephemera of the late 17th century. Examples of zigzags * The trace of a triangle wave or a sawtooth wave is a zigzag. * Pinking shears are designed to cut cloth or paper with a zigzag edge, to lessen fraying. * In sewing, a ''zigzag stitch'' is a sewing machine, machine stitch in a zigzag pattern. * The zigzag arch is an architectural embellishment used in Islamic architecture, Islamic, Byzantine architecture, Byzantine, Norman archite ...

432nd Wing
The 432nd Wing is a United States Air Force unit assigned to Air Combat Command at Creech Air Force Base near Indian Springs, Nevada. It flies General Atomics MQ-9 Reaper and RQ-170 Sentinel Unmanned aerial vehicles. The group operates unmanned reconnaissance aircraft which provide real-time reconnaissance, surveillance, and precision attack against fixed and time-critical targets. The 432nd Air Expeditionary Wing is a provisional unit assigned to Air Combat Command and is the designation for components of the 432nd Wing when deployed into combat areas as part of the Global War on Terror. Overview The wing is the first United States Air Force wing dedicated to unmanned aircraft systems: MQ-9 Reaper and RQ-170 Sentinel. The wing stood up 1 May 2007 at Creech Air Force Base, Nevada. The wing has dual reporting responsibilities to Ninth Air Force and U.S. Air Forces Central Command (USAFCENT) (as the 432nd AEW) at Shaw Air Force Base, South Carolina, as well as to Twelfth Air Fo ...

General Atomics MQ-9 Reaper
The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV, one component of an unmanned aircraft system (UAS)) capable of remotely controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate ground control by humans. The MQ-9 is a larger, heavier, more capable aircraft than the earlier General Atomics MQ-1 Predator and can be controlled by the same ground systems. The Reaper has a 950- shaft-horsepower (712 kW) turboprop engine (compared to the Predator's piston engine). The greater power allows the Reaper to carry 15 times more ordnance payload and cruise at about three times the speed of the MQ-1. The aircraft is monitored and controlled, including weapons employment, by aircrew in the Ground Control Station (GCS). The MQ-9 ...

General Atomics MQ-1 Predator
The General Atomics MQ-1 Predator (often referred to as the Predator drone) is an American remotely piloted aircraft (RPA) built by General Atomics that was used primarily by the United States Air Force (USAF) and Central Intelligence Agency (CIA). Conceived in the early 1990s for aerial reconnaissance and forward observation roles, the Predator carries cameras and other sensors. It was modified and upgraded to carry and fire two AGM-114 Hellfire missiles or other munitions. The aircraft entered service in 1995, and saw combat in the war in Afghanistan, Pakistan, the NATO intervention in Bosnia, the NATO bombing of Yugoslavia, the Iraq War, Yemen, the 2011 Libyan civil war, the 2014 intervention in Syria, and Somalia. The USAF describes the Predator as a "Tier II" MALE UAS (medium-altitude, long-endurance unmanned aircraft system). The UAS consists of four aircraft or "air vehicles" with sensors, a ground control station (GCS), and a primary satellite link communication ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine. The aircraft never flew, but a patent was filed for routing exhaust gases into the duct to augment thrust. * 1914: Auguste Rateau suggests using exhaust-powered compressor – a turbocharger – to improve high-altitude performance; not accepted after the ...
