Denel Dynamics Umbani
The Umbani is a precision-guided bomb kit manufactured by Denel Dynamics in South Africa. It consists of a number of modules fitted to NATO standard Mk81, Mk82 or Mk83 low drag free-fall bombs to convert them into guided glide bombs. Design The modular kit consists of a number units that are attached to a standard Mk80-series bomb. A guidance system and large tail fins are the most basic form of the system, optional folding wings and a rocket motor may be added to increase the stand-off range up to or add a low-level launch capability. Range using different configurations: * Standard bomb kit - 40 km * With folding wing kit - 120 km * With wing kit and Extended Range (ER) module - 200 km Guidance The weapon's all-weather, day and night capability is due to the GPS–INS guidance system. Increasing accuracy to a claimed 3m CEP is possible by adding an imaging infrared or a semi-active laser seeker terminal guidance system. Testing and qualification The system w ...

Test Flight And Development Centre SAAF
The Test Flight and Development Centre is a unit of the South African Air Force. It is a test flight and evaluation organisation. Due to South Africa's apartheid policies of the 1960s, a number of countries instituted an arms boycott against it. This forced the SAAF to create an indigenous flight testing and development capability to research new technologies and methods and update old ones, and in this light a former graduate of the Empire Test Pilots' School (ETPS) was appointed the SAAF's Chief Test Pilot in 1967 and tasked with improving and expanding the air force's test flying and evaluation capabilities. In 1974 another ETPS graduate took over, and was tasked with creating a specialised test flying and evaluation unit within the SAAF. The result was that the Test Flight and Development Centre was officially established on 10 August 1975 at AFB Waterkloof. Over the next few years until the imposition of the mandatory United Nations arms embargo against South Africa in 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-active Laser Seeker
Laser guidance directs a robotics system to a target position by means of a laser beam. The laser guidance of a robot is accomplished by projecting a laser light, image processing and communication to improve the accuracy of guidance. The key idea is to show goal positions to the robot by laser light projection instead of communicating them numerically. This intuitive interface simplifies directing the robot while the visual feedback improves the positioning accuracy and allows for implicit localization. The guidance system may serve also as a mediator for cooperative multiple robots. Examples of proof-of-concept experiments of directing a robot by a laser pointer are shown on video. Laser guidance spans areas of robotics, computer vision, user interface, video games, communication and smart home technologies. Commercial systems Samsung Electronics Co., Ltd. may have been using this technology in robotic vacuum cleaners since 2014. Google Inc. applied for a pa ...

Africa Aerospace And Defence
The African Aerospace and Defence Expo (AAD) is an aerospace and defence exhibition held every two years at AFB Waterkloof, in Centurion, Gauteng, South Africa. The exhibition combines a trade exhibition and an air show. The AAD began in 1975 when the South African based aviation magazine World Airnews determined that a professional aerospace exhibition was appropriate, as distinguished from the traveling "barnstorming" air shows that were then prominent. The first event was held October 1975 as "Aviation Africa", at Lanseria Airport near Johannesburg, South Africa under the sponsorship of the Commercial Aviation Association of Southern Africa. The same year, Lt. General Bob Rogers of the South African Air Force instituted an open day at AFB Waterkloof, in Centurion, which eventually turned into the Defence Exhibition of South Africa (DEXSA). In 2000, Aviation Africa and DEXSA combined to become AAD. In 2006, the exhibition moved to AFB Ysterplaat in Cape Town Cape Town ( ...

South African Rand
The South African rand, or simply the rand, ( sign: R; code: ZAR) is the official currency of the Southern African Common Monetary Area: South Africa, Namibia (alongside the Namibian dollar), Lesotho (alongside the Lesotho loti) and Eswatini (alongside the Swazi lilangeni). It is subdivided into 100 cents (sign: "c"). The South African rand is legal tender in the Common Monetary Area member states of Namibia, Lesotho and Eswatini, with these three countries also having their own national currency (the dollar, the loti and the lilangeni respectively) pegged with the rand at parity and still widely accepted as substitutes. The rand was also legal tender in Botswana until 1976, when the pula replaced the rand at par. Etymology The rand takes its name from the Witwatersrand ("white waters' ridge" in English, ''rand'' being the Dutch and Afrikaans word for 'ridge'), the ridge upon which Johannesburg is built and where most of South Africa's gold deposits were found.

GBU-12 Paveway II
The GBU-12 Paveway II is an American aerial laser-guided bomb, based on the Mk 82 500-pound (227 kg) general-purpose bomb, but with the addition of a nose-mounted laser seeker and fins for guidance. A member of the Paveway series of weapons, Paveway II entered into service c. 1976. It is currently in service with the U.S. Air Force, U.S. Navy, U.S. Marine Corps, and various other air forces. Development and deployment The development of the GBU-12 traces back to the Vietnam War. The U.S. Air Force wanted a greater variety of laser-guided bombs, especially a lighter and more maneuverable one to be able to hit moving targets on the Ho Chi Minh trail. Earlier designs of guided bombs such as the BOLT-117 were quickly superseded by the Paveway series of add-on kits for conventional bombs. GBU-12 bombs (along with the balance of the Paveway series) are produced by defense contractors Lockheed Martin and Raytheon. Raytheon began production after purchasing the product line from ...

Saab JAS 39 Gripen
The Saab JAS 39 Gripen (; English: ''griffin'') is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace and defense company Saab AB. The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. Later aircraft are fully NATO interoperable. , more than 271 Gripens of all models, A–F, have been built. In 1979, the Swedish government began development studies for "an aircraft for fighter, attack, and reconnaissance" (''ett jakt-, attack- och spaningsflygplan'', hence "JAS") to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force. A new design from Saab was selected and developed as the JAS 39. The first flight occurred in 1988, with delivery of the first serial production airplane in 1993. It entered service with the Swedish Air Force in 1996. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003. To marke ...

Lead-in Fighter Trainer
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAE Systems Hawk
The BAE Systems Hawk is a British single-engine, jet-powered advanced trainer aircraft. It was first flown at Dunsfold, Surrey, in 1974 as the Hawker Siddeley Hawk, and subsequently produced by its successor companies, British Aerospace and BAE Systems. It has been used in a training capacity and as a low-cost combat aircraft. Operators of the Hawk include the Royal Air Force (notably the Red Arrows display team) and several foreign military operators. The Hawk is still in production in the UK and under licence in India by Hindustan Aeronautics Limited (HAL), with over 900 Hawks sold to 18 operators around the world. Development Origins In 1964, the Royal Air Force specified a requirement (Air Staff Target, AST, 362) for a new fast jet trainer to replace the Folland Gnat. The SEPECAT Jaguar was originally intended for this role, but it was soon realised that it would be too complex an aircraft for fast jet training and only a small number of two-seat versions were purchas ...

Dassault Mirage F1
The Dassault Mirage F1 is a French fighter and attack aircraft designed and manufactured by Dassault Aviation. It was developed as a successor to the popular Mirage III family. During the 1960s, Dassault commenced development of what would become the Mirage F1 as a private venture, alongside the larger Mirage F2. Work on the F1 eventually took precedence over the costlier F2, which was cancelled during the late 1960s. The French Air Force (''Armée de l'Air'') took interest in the fledgling fighter to meet its requirement for an all-weather interceptor aircraft. Accordingly, initial production units were equipped with the Thomson-CSF Cyrano IV monopulse radar. During the latter half of 1974, the Mirage F1 entered service in the French Air Force. Shortly thereafter, the type was deployed as the main interceptor of the French Air Force, a capacity which it continued to serve in until the arrival of the Mirage 2000. It later transitioned to an aerial reconnaissance role. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
