PAIC Império SP1
The PAIC Império SP1 is an experimental unmanned aerial vehicle (UAV) developed and manufactured by the Portuguese Aerospace Industry Consortium (PAIC) and Lockheed Martin Mission Systems and Sensors to support civilian protection agencies in the wildfire detection and maritime patrol roles. Império SP1 was developed under the PAIC Império UAS program, which was established in July 2008 as result of the offset compensation that was part of the contract for the modernization of the Portuguese Air Force's P-3C Orion aircraft. As such, development started in April 2009 and was funded by the Portuguese government and Lockheed Martin. The program had a duration of four years and was completed in December 2012. The development was led by the Portuguese Aerospace Industry Association (PEMAS) and is managed by X Aerosystems. In addition to these two companies, the research and development consortium includes Active Space Technologies, CeNTI, Critical Software, EDISOFT, EMPORDEF, Iber ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Pegaz 011
The PEGAZ 011 ( sr, text=Пегаз, translation=Pegasus) is a medium-range tactical UAV for day and night attack (armed variant), reconnaissance and surveillance missions, target acquisition and designation developed by Military Technical Institute in Serbia and produced by Utva Aviation Industry, subsidiary of Yugoimport SDPR. Its flight autonomy is over 12 hours, and it sends data from the height of 6,000 m. Powered by a two-cylinder boxer type of engine with 32 kW (43 HP), it reaches the maximum flight speed of 200 km/h. The PEGAZ has a maximum weight of 240 kg, including about 50 kg of reconnaissance/surveillance equipment. It is 5.4 m long with a wingspan of 6.34 m. It takes off automatically from improvised runways and performs tasks along pre-programmed flight (optional: catapult).

AAI RQ-2 Pioneer
The AAI RQ-2 Pioneer is an unmanned aerial vehicle (UAV) that had been used by the United States Navy, Marine Corps, and Army, and deployed at sea and on land from 1986 until 2007. Initially tested aboard USS ''Iowa'', the RQ-2 Pioneer was placed aboard s to provide gunnery spotting, its mission evolving into reconnaissance and surveillance, primarily for amphibious forces. It was developed jointly by AAI Corporation and Israel Aircraft Industries. The program grew out of successful testing and field operation of the Tadiran Mastiff UAV by the American and Israeli militaries. Essentially, the Pioneer is an upgraded IAI Scout which was re-engined to accommodate a greater payload by request of the US Navy. To accomplish this, the original "Limbach" two-cylinder two-stroke engine was replaced with a Fichtel & Sachs two-cylinder two-stroke. The Limbach motor used a 71 cm propeller from Propeller Engineering and Duplicating, Inc. of San Clemente, California. The newer, more powerf ...

Cork (material)
Cork is an Permeability (earth sciences), impermeable buoyancy, buoyant material, the Cork cambium, phellem layer of bark (botany), bark tissue that is harvested for commercial use primarily from ''Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The Dehesa (pastoral management), montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell (biology), cell. Cork composition varies depending on Geography, geographic origin, climate and soil conditions, Genetics, genetic origin, tree dimensions, age (virgin or reproduction), and gro ...

Empennage
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb ''empenner'' which means " to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin-boom Aircraft
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the 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, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...
