Interstate XBDR
The Interstate XBDR was a design for an assault drone - an early television-guided missile - powered by two jet engines, that was designed by the Interstate Aircraft and Engineering Corporation during the latter stages of the Second World War for use by the United States Navy. Wind tunnel tests of a scale model were conducted, however no full-scale examples of the aircraft were built before the project was cancelled. Design Referred to at the time as an "assault drone", and the only aircraft ever designated in the 'BD' series, the XBDR-1 was designed by Interstate in response to a Navy requirement in late 1943 and early 1944. The aircraft featured a tailless design,Parsch 2003 and was essentially a flying wing with a small vertical stabiliser. The XBDR-1 was intended to be powered by two Westinghouse 19B axial-flow turbojet engines, which were to be buried in the wing near the wing roots. The planned warload was not detailed, however it was planned that the assault drone w ... [...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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Interstate XBDR-1
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. The U.S. federal government first funded roadways through the Federal Aid Road Act of 1916, and began an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were still state-funded and maintained, however, and there was little in the way of national standards for road design. U.S. Highways could be anything from a two-lane country road to a major multi-lane freeway. After Dwight D. Eisenhower became president in 1953, his administration ...

Interstate TDR
The Interstate TDR was an early unmanned combat aerial vehicle — referred to at the time as an " assault drone" — developed by the Interstate Aircraft and Engineering Corporation during the Second World War for use by the United States Navy. Capable of being armed with bombs or torpedoes, 2000 aircraft were ordered, but only around 200 were built. The type saw some service in the Pacific Theater against the Japanese, but continuing developmental issues affecting the aircraft, along with the success of operations using more conventional weapons, led to the decision being made to cancel the assault drone program in October 1944. Design and development In 1936, Lieutenant Commander Delmar S. Fahrney proposed that unpiloted, remotely controlled aircraft had potential for use by the United States Navy in combat operations. Due to the limitations of the technology of the time, development of the "assault drone" project was given a low priority, but by the early 1940s the developme ...

Horten Ho 229
The Horten H.IX, RLM designation Ho 229 (or Gotha Go 229 for extensive re-design work done by Gotha to prepare the aircraft for mass production) was a German prototype fighter/bomber initially designed by Reimar and Walter Horten to be built by Gothaer Waggonfabrik. Developed at a late stage of the Second World War, it was the first flying wing to be powered by jet engines.Green 1970, p. 247. The Ho 229 had been designed in response to a call by Hermann Göring, the head of the Luftwaffe, in 1943 for light bomber designs capable of meeting the "3×1000" requirement; namely, to carry of bombs a distance of with a speed of . Only jet propulsion was capable of achieving the required speed, but such engines were relatively primitive and extremely fuel-hungry, necessitating considerable effort across the rest of the design in order to satisfy the range requirement as well. The flying wing configuration was favoured by the Horten brothers due to its high aerodynamic efficiency, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorgon (U
A Gorgon ( ; grc, Γοργών, Gorgṓn, or grc, Γοργώ, Gorgṓ, label=none) is a creature in Greek mythology. Gorgons occur in the earliest examples of Greek literature. While descriptions of Gorgons vary, the term most commonly refers to three sisters who are described as having hair made of living, venomous snakes and horrifying visages that turned those who beheld them to stone. Traditionally, two of the Gorgons, Stheno and Euryale, were immortal, but their sister Medusa was not and was slain by the demigod and hero Perseus. Etymology The name derives from the Ancient Greek word (), which means 'grim or dreadful', and appears to come from the same root as the Sanskrit word (), which means a guttural sound, similar to the growling of a beast, thus, possibly originating as an onomatopoeia. Depictions Gorgons were a popular image in Greek mythology, appearing in the earliest of written records of Ancient Greek religious beliefs such as those of Homer, which may da ...

History Of Unmanned Aerial Vehicles
UAVs include both autonomous (capable of operating without human input) Drone (aircraft), drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty first century technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation. A UAV differs from a cruise missile in that a UAV is intended to be recovered after its mission, while a cruise missile impacts its target. A military UAV may carry and fire munitions on board, while a cruise missile is a munition. Loitering munitions are a class of unmanned aircraft intermediate between them. Early development Austrian incendiary balloon attack on Venice The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, serving as a balloon carrier (the precursor to the aircraft carrier) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for wikt:hollow, hollow or open-shaped object ...

Load Factor (aeronautics)
In aeronautics, the load factor is the ratio of the lift of an aircraft to its weightHurt, page 37 and represents a global measure of the stress ("load") to which the structure of the aircraft is subjected: : n = \frac, where : n is the load factor, : L is the lift : W is the weight. Since the load factor is the ratio of two forces, it is dimensionless. However, its units are traditionally referred to as g, because of the relation between load factor and apparent acceleration of gravity felt on board the aircraft. A load factor of one, or 1 g, represents conditions in straight and level flight, where the lift is equal to the weight. Load factors greater or less than one (or even negative) are the result of maneuvers or wind gusts. Load factor and g The fact that the load factor is commonly expressed in ''g'' units does not mean that it is dimensionally the same as the acceleration of gravity, also indicated with ''g''. The load factor is strictly non-dimensional. The use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Aeronautics
The Bureau of Aeronautics (BuAer) was the U.S. Navy's material-support organization for naval aviation from 1921 to 1959. The bureau had "cognizance" (''i.e.'', responsibility) for the design, procurement, and support of naval aircraft and related systems. Aerial weapons, however, were under the cognizance of the Navy's Bureau of Ordnance (BuOrd). Origins The USN's first attempt for naval aviation began in 1908 when it conducted observations of the Wright Brothers aircraft at Fort Myer, Virginia.https://www.history.navy.mil/content/dam/nhhc/research/histories/naval-aviation/pdf/History%20(1).pdf First tests and Naval Aviation Corps The first test of an aircraft from naval vessel was in 1910 when a Curtiss Model D flown by Eugene Burton Ely took off from the USS Birmingham (CL-2) and again on USS Pennsylvania (ACR-4) in early 1911. These test was enough for the USN to establish naval aviation units in the summer of 1911. The purchase of the first naval aircraft in May 1911 and ...
