Safran Patroller
The Patroller is a French medium-altitude long-endurance unmanned aerial vehicle developed and manufactured by Safran Electronics & Defense (formerly by SAGEM). The airframe is based on the Stemme ASP S15 motor glider. The first flight was in June 2009 at Kemijarvi in Finland; it was shown at the 2009 Paris Air Show. The Patroller is a Medium-altitude long-endurance unmanned aerial vehicle (MALE) by the definition of the NATO. It completed another series of flight tests in July 2010, which demonstrated it is capable of missions lasting 20–30 hours; it can carry a 250 kg payload (including 80 kg under each wing). The Patroller will carry out imaging and surveillance trials in southern France, detecting forest fires. The Patroller uses the same ground control station as Sperwer II. A Ku-band datalink is used; range is limited to 200 km (line of sight). Safran Electronics & Defense and Egyptian aircraft factory AOI have signed a collaboration agreement con ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Sperwer II
The SAGEM Sperwer (Pronounced ''Spehr-wuhr'', Dutch for Sparrowhawk) is an unmanned aerial vehicle manufactured by the French firm SAGEM. The aircraft is piloted remotely and can cruise at altitudes of over 16,000 feet for as long as five hours. It can send back images of targets up to 150 kilometers away from its ground control station. Operational history The Sperwer is currently in service with the French Army (61e régiment d'artillerie), the Royal Netherlands Air Force, Swedish Air Force, United States Air National Guard, Hellenic Army (Greece) with the Netherlands in the process of removing them from front line use. Canadian Armed Forces operated the Sperwer in Afghanistan between 2003 and its last mission on 18 April 2009 when it was replaced with the Israeli built IAI Heron. The Royal Danish Army also bought Sperwer, but a series of problems forced the Ministry of Defence to cancel the programme and sell the remainder to Canada.

Aircraft First Flown In 2009
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-engined Aircraft
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive comp ...

Unmanned Military Aircraft Of France
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. It has been reported that the armed forces of more than 100 countries have approximately 170 different types of drones in service. 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) **Self-driving truck **Driverless tractor * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft, either fixed-wing or rotorwing, commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium ...

Thales Watchkeeper WK450
The Thales Watchkeeper WK450 is an unmanned aerial vehicle (UAV) for intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) formerly used by the British Army. It was developed by UAV Tactical Systems (U-TacS), a joint venture of Elbit Systems UK and Thales UK, and is based on Elbit's Hermes 450. The Watchkeeper entered full service in 2019, but was retired by March 2025, significantly before its earlier planned out-of-service date of 2042. Overview The Watchkeeper WK450 is based on the Elbit Hermes 450 UAV and is built in the UK by a joint venture company, UAV Tactical Systems (U-TacS), set up by the Israeli company Elbit Systems (51% ownership) and the Thales group. The Watchkeeper is 6.5m long, with a 10.9m wingspan. Its cruising speed is , and it can operate at an altitude of . It has a takeoff weight of 485 kg, a typical endurance of 14 hours, a payload capacity of 150 kg and uses a rotary Wankel engine provided by UAV Engines Ltd, a wholly ...

Elbit Hermes 450
The Hermes 450 is a medium-sized multi-payload unmanned aerial vehicle (UAV) designed by Israeli defence company Elbit for tactical long endurance missions. It has an endurance of over 20 hours, with a primary mission of reconnaissance, surveillance and communications relay. Payload options include electro-optical/infrared sensors, communications and electronic intelligence, synthetic-aperture radar/ground-moving target indication, electronic warfare, and hyperspectral sensors. Overview The Hermes 450 is a medium-sized UAV with a cylindrical shaped fuselage, high straight wings and a V-tail.

Arab Organization For Industrialization
The Arab Organization for Industrialization (AOI) () is a company established in 1975 by Egypt, Saudi Arabia, United Arab Emirates and Qatar to supervise the collective development of the Arab defense industry. Following a gradual deterioration in relations between the AOI member-states, Egypt became sole owner of AOI in 1993. As well as meeting the requirements of the Egyptian military, AOI directs spare capacity to civilian programmes, including civilian transport and sanitation equipment; additionally, AOI has stated its intention of entering the wind power sector. Initially an institution of Pan-Arabism, Saudi Arabia and the United Arab Emirates returned their shares in AOI, valued at US$1.8 billion, to Egypt in 1993, leaving AOI wholly owned by Egypt. AOI has approximately 16,000 employees, out of which 1,250 are engineers. AOI fully owns 12 factories and shares in 1 joint-venture, besides the Arab Institute for Development Technology.
