Hongdu JL-8
The Hongdu JL-8 (Nanchang JL-8), also known as the Karakorum-8 or K-8 for short, is a two-seat intermediate jet trainer and a light attack aircraft designed in the People's Republic of China by China Nanchang Aircraft Manufacturing Corporation. The primary contractor is the Hongdu Aviation Industry Corporation. Development The JL-8 trainer was proposed as a joint cooperation effort between the governments of Pakistan and the People's Republic of China in 1986. The name was changed on the suggestion of Pakistan's then President Zia ul Haq to Karakoram-8 to represent the friendship between the two countries. Work on the design started in 1987 at Nanchang Aircraft Manufacturing Company (NAMC) at Nanchang, Jiangshi Province in South Central China. The Chinese chief designer of the aircraft was Shi Ping (), heading a team of over 100 Chinese Engineers, while Air Cdr Muhammad Younas Tbt (M), SI(M) was the chief designer from the Pakistani side leading a team of over 20 Pakistani e ...

Flight Control Surfaces
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, but once aloft, the aircraft proved uncontrollable, often with disastrous results. The development of effective flight controls is what allowed stable flight. This article describes the control surfaces used on a fixed-wing aircraft of conventional design. Other fixed-wing aircraft configurations may use different control surfaces but the basic principles remain. The controls (stick and rudder) for rotary wing aircraft (helicopter or autogyro) accomplish the same motions about the three axes of rotation, but manipulate the rotating flight controls (main rotor disk and tail rotor disk) in a completely different manner. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Control System
A conventional Fixed-wing aircraft, fixed-wing aircraft flight control system consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered as flight controls as they change speed. The fundamentals of aircraft controls are explained in flight dynamics (fixed-wing aircraft), flight dynamics. This article centers on the operating mechanisms of the flight controls. The basic system in use on aircraft first appeared in a readily recognizable form as early as April 1908, on Louis Blériot's Blériot VIII pioneer-era monoplane design. Cockpit controls Primary controls Generally, the primary cockpit flight controls are arranged as follows:Langewiesche, WolfgangStick and Rudder: An Explanation of the Art of Flying McGraw-Hill Professional, 1990, , . * a Yoke (aircraft), control yoke (also known as a control column), centre s ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer Anth ...

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Multi-role Aircraft
A multirole combat aircraft (MRCA) is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses. Definition The term "multirole" was originally reserved for aircraft designed with the aim of using a common airframe for multiple tasks where the same basic airframe is adapted to a number of differing roles. The main motivation for developing multirole aircraft is cost reduction in using a common airframe. More roles can be added, such as aerial reconnaissance, forward air control, and electronic-warfare aircraft. Attack missions include the subtypes air interdiction, suppression of enemy air defense (SEAD), and close air support (CAS). Multirole has also been applied to one aircraft with both major roles, a primary air-to-air combat role, and a secondary role like air-to-surface attack. However, those designed with an emphasis ...

BAE 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 ...

Hardpoint
A hardpoint is an attachment location on a structural frame designed to transfer force and carry an external or internal load. The term is usually used to refer to the mounting points (more formally known as a weapon station or station) on the airframe of military aircrafts that carry weapons (e.g. gun pods and rocket pods), ordnances (bombs and missiles) and support equipments (e.g. flares and countermeasures, targeting pods or drop tanks), and also include hardpoints (also known as pylons) on the wings or fuselage of a military transport aircraft, commercial airliner or private jet where external turbofan jet engines are often mounted. Aircraft In aeronautics, the term ''station'' is used to refer to a point of carriage on the frame of an aircraft. A station is usually rated to carry a certain amount of payload. It is a design number which already has taken the rated g-forces of the frame into account. Therefore, point loads on the structure from externally or internally mo ...
