KAI RQ-101
The KAI RQ-101 Songgolmae () is a South Korean military unmanned aerial vehicle (UAV) developed by the Agency for Defense Development (ADD) and the Korea Aerospace Industries (KAI) in 2000. RQ-101 is an unarmed UAV designed for corps commanders and has been deployed and serviced by the South Korean Army since 2002 to collect military intelligence. It was officially given the name Songgolmae (, "peregrine falcon"). Development and Design The South Korean Army was using Searcher UAVs, which were introduced from Israel. In 1991, South Korea began developing its own UAVs for use in ground surveillance and reconnaissance operations by Corps-level units of the South Korean Army. Exploratory development of South Korean military UAVs was carried out from 1991 to 1992, and system development began in 1993, and operational tests were conducted to verify performance until 1997, and the development was officially completed in 2000. Officially, it is not known how many RQ-101s are in serv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Surveillance And Reconnaissance Aerial Vehicle
An unmanned surveillance and reconnaissance aerial vehicle, is an unarmed military unmanned aerial vehicle, UAV that is used for intelligence, surveillance, target acquisition, and reconnaissance (ISTAR). Unlike unmanned combat aerial vehicle (UCAV), this type of system is not designed to carry aircraft ordnance such as missiles, ATGMs, or aerial bomb, bombs for drone strikes. The main purpose is to provide battlefield intelligence. Small sized short-range man-portable unmanned aerial vehicles are called miniature UAV also used for battlefield intelligence. Current models The Harbin BZK-005 family encompasses reconnaissance variant like BZK-005 alongside combat-focused models like the BZK-005C. CH-1and CH-2 variants are for reconnaissance. Future models and technology demonstrators Belgium The Belgians were early adopters of reconnaissance UAVs, introducing the MBLE Épervier, "Epervier (Sparrowhawk)" UAV in the early 1970s. It was built by Manufacture Belge De Lampes Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forward-looking Infrared
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source ( thermal radiation), to create an image assembled for video output. They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm). Design Infrared light falls into two basic ranges: ''long-wave'' and ''medium-wave''. Long-wave infrared (LWIR) cameras, sometimes called "far-infrared", operate at 8 to 12 μm and can see heat sources, such as ...

Twin-boom Aircraft
A twin-boom aircraft has two wikt:Longitudinal, longitudinal auxiliary spars, or “auxiliary booms” , that may contain ancillary components such as fuel tank, fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the Empennage, tail surfaces, although on some types such as the Rutan Grizzly, Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from Twin-fuselage aircraft, twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin-fuselage aircraft, twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, ...

Line Of Sight
The line of sight, also known as visual axis or sightline (also sight line), is an imaginary line between a viewer/ observer/ spectator's eye(s) and a subject of interest, or their relative direction. The subject may be any definable object taken note of or to be taken note of by the observer, at any distance more than least distance of distinct vision. In optics, refraction of a ray due to use of lenses can cause distortion. Shadows, patterns and movement can also influence line of sight interpretation (as in optical illusions). The term "line" typically presumes that the light by which the observed object is seen travels as a straight ray, which is sometimes not the case as light can take a curved/angulated path when reflected from a mirror, refracted by a lens or density changes in the traversed media, or deflected by a gravitational field. Fields of study feature specific targets, such as vessels in navigation, marker flags or natural features in surveying, celestial objec ...

Navigation System
A navigation system is a computing system that aids in navigation. Navigation systems may be entirely on board the vehicle or vessel that the system is controlling (for example, on the ship's bridge) or located elsewhere, making use of radio or other signal transmission to control the vehicle or vessel. In some cases, a combination of these methods is used. Navigation systems may be capable of one or more of: * containing maps, which may be displayed in human-readable format via text or in a graphical format * determining a vehicle or vessel's location via sensors, maps, or information from external sources * providing suggested directions to a human in charge of a vehicle or vessel via text or speech * providing directions directly to an autonomous vehicle such as a robotic probe or guided missile * providing information on nearby vehicles or vessels, or other hazards or obstacles * providing information on traffic conditions and suggesting alternative directions * simultaneou ...

Electro-optics
Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials. It is closely related to photonics, the branch of optics that involves the application of the generation of photons. It is not only concerned with the " electro–optic effect", since it deals with the interaction between the electromagnetic ( optical) and the electrical ( electronic) states of materials. Electro-optical devices The electro-optic effect is a change in the optical properties of an optically active material in response to changes in an electric field. This interaction usually results in a change in the birefringence Birefringence, also called double refraction, is the optical property of a material having a refractive index that depends on the polari ...

Data Link
A data link is a means of telecommunications link, connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex (telecommunications), Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
