China Northwest Airlines Flight 2303
China Northwest Airlines Flight 2303 was a domestic flight from Xi'an to Guangzhou, People's Republic of China. On June 6, 1994, the aircraft operating the flight, a Tupolev Tu-154M, broke up in-flight and crashed as a result of an autopilot malfunction which caused violent shaking and overstressed the airframe. All 160 people on board were killed. As of 2023, it remains the deadliest airplane crash ever in mainland China. Aircraft The aircraft was a Tupolev Tu-154M (registration B-2610, factory 86A740, serial no. 0740). It was completed by the Kuibyshev Aviation Plant (KuAPO) on December 22, 1986, and was immediately transferred to the Civil Aviation Administration of China (CAAC). On July 1, 1988, due to reorganization, CAAC transferred the aircraft to China Northwest Airlines. The aircraft was powered with three Soloviev D-30KU-154-II low-bypass turbofan engines from the Rybinsk Engine Plant. On the day of the accident, the aircraft had 12,507 flying hours and 6,651 takeoff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Aviation Administration Of China
The Civil Aviation Administration of China (CAAC; ) is the Chinese civil aviation authority under the Ministry of Transport. It oversees civil aviation and investigates aviation accidents and incidents. As the aviation authority responsible for China, it concludes civil aviation agreements with other aviation authorities, including those of the Special administrative regions of China which are categorized as "special domestic." It directly operated its own airline, China's aviation monopoly, until 1988. The agency is headquartered in Dongcheng District, Beijing. The CAAC does not share the responsibility of managing China's airspace with the Central Military Commission under the regulations in the Civil Aviation Law of the People's Republic of China. History On November 2, 1949, shortly after the founding of the People's Republic of China, the CCP Central Committee decided to found the Civil Aviation Agency under the name of the People's Revolutionary Military Commission, ...

June 1994 Events In Asia
June is the sixth month of the year in the Julian and Gregorian calendars and is the second of four months to have a length of 30 days, and the third of five months to have a length of less than 31 days. June contains the summer solstice in the Northern Hemisphere, the day with the most daylight hours, and the winter solstice in the Southern Hemisphere, the day with the fewest daylight hours (excluding polar regions in both cases). June in the Northern Hemisphere is the seasonal equivalent to December in the Southern Hemisphere and vice versa. In the Northern Hemisphere, the beginning of the traditional astronomical summer is 21 June (meteorological summer begins on 1 June). In the Southern Hemisphere, meteorological winter begins on 1 June. At the start of June, the sun rises in the constellation of Taurus; at the end of June, the sun rises in the constellation of Gemini. However, due to the precession of the equinoxes, June begins with the sun in the astrological sign o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guangzhou Baiyun International Airport
Guangzhou Baiyun International Airport is the major airport of Guangzhou, Guangdong province, in Southern China. Both airport codes were inherited from the former Baiyun Airport, and the IATA code is derived from Guangzhou's historical romanization ''Canton''. Baiyun Airport serves as a hub for China Southern Airlines, FedEx Express, 9 Air, Hainan Airlines and Shenzhen Airlines.

Aircraft 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 ...

Banked Turn
A banked turn (or banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. For a road or railroad this is usually due to the roadbed having a transverse down-slope towards the inside of the curve. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal. Turn on flat surfaces If the bank angle is zero, the surface is flat and the normal force is vertically upward. The only force keeping the vehicle turning on its path is friction, or traction. This must be large enough to provide the centripetal force, a relationship that can be expressed as an inequality, assuming the car is driving in a circle of radius ''r'': :\mu mg > . The expression on the right hand side is the centripetal acceleration multiplied by mass, the force required to turn the vehicle. The left hand side is the maximum frictional force, which equals the coefficient of friction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tait-Bryan Rotations
In physics and engineering, Davenport chained rotations are three chained intrinsic rotations about body-fixed specific axes. Euler rotations and Tait–Bryan rotations are particular cases of the Davenport general rotation decomposition. The angles of rotation are called Davenport angles because the general problem of decomposing a rotation in a sequence of three was studied first by Paul B. Davenport. The non-orthogonal rotating coordinate system may be imagined to be rigidly attached to a rigid body. In this case, it is sometimes called a ''local'' coordinate system. Given that rotation axes are solidary with the moving body, the generalized rotations can be divided into two groups (here ''x'', ''y'' and ''z'' refer to the non-orthogonal moving frame): ; Generalized Euler rotations: ; Generalized Tait–Bryan rotations: . Most of the cases belong to the second group, given that the generalized Euler rotations are a degenerated case in which first and third axes are overlapping. ...

Flight Dynamics
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft. Spacecraft flight dynamics involve three main forces: propulsive (ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
