Twin-fuselage Aircraft
A twin-fuselage aircraft has two main fuselages. It is distinct from the twin-boom configuration which has a single main fuselage with two subsidiary boom structures. Twin fuselages have been adopted for various reasons, and a few types have entered production. Early seaplanes A twin-float arrangement offers stability on the water without the need for wing tip stabilising floats. Mounting the float immediately below, or integrally with, the fuselage provides a strong airframe with minimal additional weight. During and after World War I a number of such twin-fuselage floatplanes and twin-hulled flying boats were constructed, and a few entered production. As early as 1913, the Radley-England Waterplane racing flying boat demonstrated the concept at the hands of pilot Gordon England. The Twin Blackburn of 1915 was a long-range floatplane for anti-Zeppelin patrol. A handful of production examples were delivered but few were used operationally. Savoia-Marchetti produced two twin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American XP-82 Twin Mustang 44-83887
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt Me 309
The Messerschmitt Me 309 was a prototype Nazi Germany, German Fighter aircraft, fighter, designed in the early years of World War II to replace the Messerschmitt Bf 109. Although it had many advanced features, the Me 309's performance left much to be desired and it had so many problems that the project was cancelled with only four prototypes built. The Me 309 was one of two failed Messerschmitt projects intended to replace the Bf 109, the other being the Messerschmitt Me 209 (1943), 1943 Me 209 project. Design and development Messerschmitt's failure to resolve the stability and other problems of the Me 209 project during 1940 caused Willy Messerschmitt to scrap much of the earlier design work when he commissioned wind tunnel testing of new wing designs and the cockpit canopy (aircraft), canopy in January 1941. Other changes included dropping the Daimler-Benz DB 601 engine and substituting Tricycle gear, tricycle landing gear for the previous conventional landing gear, tail-dr ...

Roc (mythology)
The roc is an enormous legendary bird of prey in the popular mythology of the Middle East. The roc appears in Arab geographies and natural history, popularized in Arabian fairy tales and sailors' folklore. Ibn Battuta tells of a mountain hovering in the air over the China Seas, which was the roc. The story collection ''One Thousand and One Nights'' includes tales "Abd al-Rahman the Maghribi's Story of the Rukh" and "Sinbad the Sailor", both of which include the roc. Etymology The English form ''roc'' originates via Antoine Galland's French from Arabic ''ruḵḵ'' () and that from Persian language, Persian ''ruḵ'' ().roc /[phonetic transcription]/ n. Also (earlier) ✝roche, ✝rock, ✝ruc(k), ✝rukh. L16 [Sp. ''rocho'', ''ruc'' f. Arab. ''ruḵḵ'', f. Pers.

Scaled Composites Stratolaunch
The Scaled Composites Model 351 Stratolaunch or Roc is an aircraft built by Scaled Composites for Stratolaunch Systems to carry air-launch-to-orbit (ALTO) rockets, and subsequently repurposed to offer air launch hypersonic flight testing after a change of ownership. It was announced in December 2011, rolled out in May 2017, and flew for the first time on April 13, 2019, shortly after the death of founder Paul Allen. The aircraft features a twin-fuselage design and the longest wingspan ever flown, at , surpassing the Hughes H-4 Hercules "Spruce Goose" flying boat of . The Stratolaunch is intended to carry a payload and has a maximum takeoff weight. Stratolaunch ceased operations in May 2019, shortly after the first flight of the Roc, and placed all company assets, including the aircraft, for sale by June 2019.

Scaled Composites SpaceShipTwo
The Scaled Composites Model 339 SpaceShipTwo (SS2) was an air-launched suborbital spaceplane type designed for space tourism. It was manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic. SpaceShipTwo was carried to its launch altitude by a Scaled Composites White Knight Two, before being released to fly on into the upper atmosphere powered by its rocket engine. It then glided back to Earth and performed a conventional runway landing. The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California. On 29 April 2013, after nearly three years of unpowered testing, the first SS2 constructed successfully performed its first powered test flight. Virgin Galactic planned to operate a fleet of five SpaceShipTwo spaceplanes in a private passenger-carrying service and took bookings for some time, with a suborbital flight carrying a ticket price of US$250,000 in 2015. The spaceplane was also used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaled Composites White Knight Two
The Scaled Composites Model 348 White Knight Two (WK2) is a quadjet cargo aircraft that was used to lift the SpaceShipTwo (SS2) spacecraft to release altitude. It was developed by Scaled Composites from 2007 to 2010 as the first stage of Tier 1b, a two-stage to suborbital-space crewed launch system. WK2 is based on the successful mothership to SpaceShipOne, White Knight, which itself was based on Proteus. With an "open architecture" design and explicit plans for multi-purpose use, the aircraft could also operate as a zero-g aircraft for passenger training or microgravity science flights, handle missions in high-altitude testing more generally, or be used to launch payloads other than SpaceShipTwo. A study of use of the aircraft as a forest fire water bomber has also been mentioned, one that would utilize a large carbon composite water tank that could be quickly replenished to make repeat runs over fires. The first White Knight Two is named VMS ''Eve'' after Richard Branson' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaled Composites White Knight
The Scaled Composites Model 318 White Knight (now also called ''White Knight One'') is a jet-powered carrier aircraft that was used to launch its companion SpaceShipOne, an experimental spaceplane. The White Knight and SpaceShipOne were designed by Burt Rutan and manufactured by Scaled Composites, a private company founded by Rutan in 1982. On three separate flights in 2004, White Knight conducted SpaceShipOne into flight, and SpaceShipOne then performed a sub-orbital spaceflight, becoming the first private craft to reach space. The White Knight is notable as an example of a mother ship which carried a parasite aircraft into flight, releasing the latter which would then execute a high-altitude flight, or a sub-orbital spaceflight. This flight profile is shared with ''The High and Mighty One'' and ''Balls 8'', two modified B-52s which carried the North American X-15 into flight. It is also shared with White Knight Two, a descendant which carries SpaceShipTwo into flight as part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conroy Virtus
The Conroy Virtus was a proposed American large transport aircraft intended to carry the Space Shuttle. Designed, beginning in 1974, by John M. Conroy of the Turbo-Three Corporation, it was to incorporate a pair of Boeing B-52 Stratofortress fuselages to form a new craft using existing parts for cost-savings. While the project was seriously considered, it proved impractically large and NASA chose to develop the Boeing 747–based Shuttle Carrier Aircraft, Shuttle Carrier from surplus commercial aircraft instead. History The Space Shuttle was originally designed to use on-board turbofan engines for propulsion within the atmosphere on re-entry and for ferry flights between landing sites, such as Edwards Air Force Base, the White Sands Missile Range or contingency landing sites such as Easter Island, to the launch site at Kennedy Space Center at Cape Canaveral. When the air-breathing engines were deleted from the Shuttle design due to cost and weight concerns, a requirement arose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mothership
A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft. Examples include bomber aircraft, bombers converted to carry experimental aircraft to altitudes where they can conduct their research (such as the B-52 carrying the X-15), or ships that carry small submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atlantis II carrying the DSV Alvin, ''Alvin''). A mother ship may also be used to recover smaller craft, or go its own way after releasing them. A smaller vessel serving or caring for ''larger'' craft is usually called a tender ship, tender. Maritime craft During World War II, the German Type XIV submarine or ''Milchkuh'' (Milk cow) was a type of large submarine used to resupply the U-boats. Mother ships can carry small submersibles and submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atla ...

Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict. After the end of World War II in 1945, Korea, which had been a Korea under Japanese rule, Japanese colony for 35 years, was Division of Korea, divided by the Soviet Union and the United States into two occupation zones at the 38th parallel north, 38th parallel, with plans for a future independent state. Due to political disagreements and influence from their backers, the zones formed their governments in 1948. North Korea was led by Kim Il S ...

North American F-82 Twin Mustang
The North American F-82 Twin Mustang is an American long-range escort fighter aircraft, fighter. Based on the North American P-51 Mustang, the F-82 was designed as an escort for the Boeing B-29 Superfortress in World War II, but the war ended well before the first production units were operational. The F-82 was the last American piston-engined fighter ordered into production by the United States Air Force. In the postwar era, Strategic Air Command used the aircraft as a long-range escort fighter. Radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the Northrop P-61 Black Widow as all-weather day/night interceptors. During the Korean War, Japan-based F-82s were among the first USAF aircraft to operate over Korea. The first three North Korean aircraft destroyed by U.S. forces were shot down by F-82s, the first being a North Korean Yakovlev Yak-11, Yak-11 downed over Gimpo International Airport, Gimpo Airfield by the USAF 68th Fighter Squadr ...
