Target Drone
A target drone is an unmanned aerial vehicle, generally remote controlled, usually used in the training of anti-aircraft crews. One of the earliest drones was the British DH.82 Queen Bee, a variant of the Tiger Moth trainer aircraft operational from 1935. Its name led to the present term "drone". In their simplest form, target drones often resemble radio-controlled model aircraft. More modern drones may use countermeasures, radar, and similar systems to mimic manned aircraft. More advanced drones are made from large, older missiles which have had their warheads removed. In the United Kingdom, obsolete Royal Air Force and Royal Navy jet and propeller-powered aircraft (such as the Fairey Firefly, Gloster Meteor and de Havilland Sea Vixen used at RAE Llanbedr between the 1950s and 1990s) have also been modified into remote-controlled drones, but such modifications are costly. With a much larger budget, the U.S. military has been more likely to convert retired aircraft or olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Globe Aircraft Corporation
The Globe Aircraft Corporation was an American aircraft manufacturer formed in 1940 in Fort Worth, Texas. It was declared bankrupt in 1947. History The Bennett Aircraft Corporation was originally formed on 5 April 1940 to develop aircraft using a Bakelite bonded plywood '' Duraloid''. The company's first design was the BTC-1 twin engined monoplane. The company was renamed the Globe Aircraft Corporation in 1941 and they produced a single-engined Continental A-80 powered Globe GC-1 Swift. With the start of the war the company abandoned plans to produce the aircraft as it concentrated on sub-contract building of 600 Beech AT-10s and components for other aircraft like the Curtiss C-46 The Curtiss C-46 Commando is a twin-engine transport aircraft derived from the Curtiss CW-20 pressurised high-altitude airliner design. Early press reports used the name "Condor III" but the Commando name was in use by early 1942 in company pub .... When wartime restrictions were removed the compa ...

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Catapult
A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. A catapult uses the sudden release of stored potential energy to propel its payload. Most convert tension or torsion energy that was more slowly and manually built up within the device before release, via springs, bows, twisted rope, elastic, or any of numerous other materials and mechanisms. In use since ancient times, the catapult has proven to be one of the most persistently effective mechanisms in warfare. In modern times the term can apply to devices ranging from a simple hand-held implement (also called a "slingshot") to a mechanism for launching aircraft from a ship. The earliest catapults date to at least the 7th century BC, with King Uzziah, of Judah, recorded as equipping the walls of Jerusalem with machines that shot "great stones". Catapults are mentioned in Yajurveda un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Opposed Piston Engine
An opposed-piston engine is a piston engine in which each cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large-scale applications such as ships, military tanks, and factories. Current manufacturers of opposed-piston engines include Fairbanks-Morse, Cummins and Achates Power. Design Compared to contemporary two-stroke engines, which used a conventional design of one piston per cylinder, the advantages of the opposed-piston engine have been recognized as: * Eliminating the cylinder head and valvetrain, which reduces weight, complexity, cost, heat loss, and friction loss of the engine. * Creating a uniflow-scavenged movement of gas through the combustion chamber, which avoided the drawbacks associated with the contemporary crossflow-scavenged designs (however later advancements have provided methods for achieving uniflow scavenging in conventional piston engine designs). * A reduced height of the en ...

Globe Aircraft
A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a ''celestial globe''. A globe shows details of its subject. A terrestrial globe shows landmasses and water bodies. It might show nations and major cities and the network of latitude and longitude lines. Some have raised relief to show mountains and other large landforms. A celestial globe shows notable stars, and may also show positions of other prominent astronomical objects. Typically, it will also divide the celestial sphere into constellations. The word ''globe'' comes from the Latin word ''globus'', meaning "sphere". Globes have a long history. The first known mention of a globe is from Strabo, describing the Globe of Crates from about 150 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s United States Special-purpose Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.
