Fleetwings BQ-1
The Fleetwings BQ-1 was an early expendable unmanned aerial vehicle — referred to at the time as an " assault drone" — developed by Fleetwings during the Second World War for use by the United States Army Air Forces. Only a single example of the type was built, the program being cancelled following the crash of the prototype on its first flight. Development Development of the BQ-1 began on July 10, 1942, under a program for the development of "aerial torpedoes" – unmanned aircraft carrying internal bombs – that had been instigated in March of that year. Fleetwings was contracted to build a single XBQ-1 assault drone,Werrell 1985, p.30. powered by two Franklin O-405-7 opposed piston engines, and fitted with a fixed landing gear in tricycle configuration. The aircraft was optionally piloted; a single-seat cockpit was installed for ferry and training flights; a fairing would replace the cockpit canopy on operational missions.Parsch 2005 The BQ-1 was intended to carry a war ...

Flying Bomb
A flying bomb is a manned or unmanned aerial vehicle or aircraft carrying a large explosive warhead, a precursor to contemporary cruise missiles. In contrast to a bomber aircraft, which is intended to release bombs and then return to its base for re-use, a flying bomb crashes into its target and is therefore itself destroyed in its attack. The term flying bomb is most frequently associated with two specific Second World War weapons, the German V-1 and the Japanese Ohka. The former was unpiloted, as the first known cruise missile ever deployed in combat; the latter carried a pilot on a kamikaze mission. Historic exemplars ''The Sphere'' of March 13, 1915 published an article on "The Possibilities of an Aerial Torpedo Controlled by Wireless", suggested by a "correspondent to the Sphere" and declared feasible by an "aviation expert". The first attempt to build a flying bomb (alternatively called an "aerial torpedo" in the Navy) was undertaken by Elmer Sperry for the US Navy in 191 ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

World War II Guided Missiles Of The United States
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...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. 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) * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium-altitude long-endurance unmanned aerial vehicle (MALE) ** Miniature UAV (SUAV) ** Delivery drone ** Micro air vehicle (MAV) ** Target drone * Autonomous spaceport drone ship * Uncrewed surface vehicle (USV) ...

1940s United States Bomber 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.

Fleetwings Aircraft
Fleetwings, later Kaiser-Fleetwings, was an American aircraft company of the 1930s and 1940s. History Fleetwings started in 1926 (under a different name) as a business based on a patented mechanical timing device, which proved particularly suited to controlling automated welding equipment. After developing the additional capacity to offer welding services, it pursued research and technology specifically related to the welding of stainless steel. In 1929, the company reorganized as Fleetwings, Inc., in Garden City, New York, to develop stainless-steel aircraft structures. The company progressed to manufacturing components for other aircraft manufacturers, including ribs and control surfaces for the Ireland "Privateer" amphibian, and ribs, flaps and tail surfaces for Grover Loening Aircraft Company, and moved to a larger location in a hangar on lower Roosevelt Field, Long Island. In 1934, it purchased the former Keystone Aircraft facility on the Delaware River in Bristol, Penns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Fairchild BQ-3
The Fairchild BQ-3, also known as the Model 79, was an early expendable unmanned aerial vehicle – referred to at the time as an " assault drone" – developed by Fairchild Aircraft from the company's AT-21 Gunner advanced trainer during the Second World War for use by the United States Army Air Forces. Two examples of the type were built and flight-tested, but the progress of guided missiles rendered the assault drone quickly obsolete, and the type was not produced. Design and development Development of the BQ-3 began in October, 1942, under a program for the development of "aerial torpedoes", later and more commonly referred to as "assault drones", that had been instigated in March of that year. Fairchild was awarded a contract for the construction of two XBQ-3 prototypes, based largely on the AT-21 Gunner advanced gunnery trainer already in United States Army Air Forces service.Parsch 2003 The XBQ-3 was a twin-engined, low-wing aircraft, fitted with retractable tricycle landi ...

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] |
Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
