Iran Aseman Airlines Flight 3704
Iran Aseman Airlines Flight 3704 was a scheduled Iranian domestic passenger flight from Iranian capital Tehran Mehrabad International Airport to Yasuj in southwest Iran. On 18 February 2018, during its approach to Yasuj, the aircraft serving the flight, an ATR 72-212 operated by Iran Aseman Airlines, crashed into Mount Dena in the Zagros Mountains near Noqol village in Semirom county, Isfahan Province. All 60 passengers and 6 crew members on board were killed. According to the interim report, which was published on 18 February 2019 by the Iranian Civil Aviation Organization (CAO), the accident was caused by multiple factors, with pilot error considered as the main cause. The investigation showed that the crew decided to continue to Yasuj despite deteriorating weather conditions in the area. During its approach, the crew elected to descend below the minimum altitude. The resulting bad weather caused the aircraft to stall. The crew failed to recover the aircraft from the sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Wave
In meteorology, lee waves are atmospheric stationary waves. The most common form is mountain waves, which are atmospheric internal gravity waves. These were discovered in 1933 by two German glider pilots, Hans Deutschmann and Wolf Hirth, above the Krkonoše. They are periodic changes of atmospheric pressure, temperature and orthometric height in a current of air caused by vertical displacement, for example orographic lift when the wind blows over a mountain or mountain range. They can also be caused by the surface wind blowing over an escarpment or plateau, or even by upper winds deflected over a thermal updraft or cloud street. The vertical motion forces periodic changes in speed and direction of the air within this air current. They always occur in groups on the lee side of the terrain that triggers them. Sometimes, mountain waves can help to enhance precipitation amounts downwind of mountain ranges. Usually a turbulent vortex, with its axis of rotation parallel to the mount ...

Ministry Of Roads And Urban Development
The Ministry of Roads and Urban Development ( fa, وزارت راه و شهرسازی, ''Vezārat-e Rāh-e va Shahrsāzi'') is an Iranian government body in charge of providing and regulating the country's transport infrastructure (including roads, railroads, shipping lanes and airways), as well as setting policies for the housing sector and construction industry. This Ministry was formed on 27 June 2011, when the two ministries of Housing and Urban Development and Roads and Transportation were merged. Companies and organizations, such as Iran Air, I.R. Iran Railways, and Iran's Ports and Maritime Organization (PMO) function under the supervision of the Ministry of Roads and Urban Development. The Ministry follows a set of objectives and missions in the transport, urban development and housing sectors. These include, but are not limited to: formulating and implementing policies in these sectors, providing and maintaining infrastructure, creating national plans for urban dev ...

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] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Revolutionary Guard Corps
The Islamic Revolutionary Guard Corps (IRGC; fa, سپاه پاسداران انقلاب اسلامی, Sepāh-e Pāsdārān-e Enghelāb-e Eslāmi, lit=Army of Guardians of the Islamic Revolution also Sepāh or Pasdaran for short) is a branch of the Iranian Armed Forces, founded after the Iranian Revolution on 22 April 1979 by order of Ayatollah Ruhollah Khomeini.IISS Military Balance 2006, Routledge for the IISS, London, 2006, p. 187 Whereas the Iranian Army defends Iranian borders and maintains internal order, according to the Iranian constitution, the Revolutionary Guard is intended to protect the country's Islamic republic political system, which supporters believe includes preventing foreign interference and coups by the military or "deviant movements". The IRGC is designated as a terrorist organization by the governments of Bahrain, Saudi Arabia and the United States. As of 2011, the Revolutionary Guards had at least 250,000 military personnel including ground, aerosp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
