Aeroflot Flight 1661
Aeroflot Flight 1661 was a passenger flight operated by an Antonov An-24 that crashed during its initial climb, 25 minutes after take-off from Tolmachevo Airport on 1 April 1970. All 45 people on board perished. An investigation revealed that the Antonov collided with a radiosonde, causing a loss of control. Accident Flight 1661 was a scheduled domestic flight from Novosibirsk to Bratsk, Russia, with an intermediate stop at Krasnoyarsk. At 03:42 local time the An-24 departed Tolmachevo Airport from runway 25 on a heading of 251°. Shortly after take-off, the aircraft made a turn to the left, and at 03:53 contacted air traffic control (ATC) and reported their altitude as 4,200 meters. They then received clearance to continue climbing to 6,000 meters. At 04:10 ATC attempted to contact flight 1661, but no further transmissions from the Antonov were received. The crashed aircraft was found in a field approximately 142 km from Tolmachevo Airport; there were no survivors. Among the v ...

Weather Balloon
A weather balloon, also known as sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as ''transosondes''. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and the height of cloud layers. For such balloons, a theodolite or total station is used to track the balloon's azimuth and elevation, which are then converted to estimated wind speed and direction and/or cloud height, as applicable. Weather balloons are launched around the world for observations used to diagnose current conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radome
A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes spherical, geodesic dome, geodesic, planar, etc. depending on the particular application, using various construction materials such as fiberglass, polytetrafluoroethylene, polytetrafluoroethylene (PTFE)-coated fabric, and others. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally serve as radomes. On aircraft used for airborne early warning and control (AEW&C), a rotating radome, often called a "rotodome", is mounted on the top of the fuselage for 360-degr ...

Aviation Accidents And Incidents In The Soviet Union
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Accidents And Incidents Involving The Antonov An-24
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into someth ...

Aeroflot Accidents And Incidents In The 1970s
Aeroflot, the Soviet Union's national carrier, experienced a number of serious accidents and incidents during the 1970s. The airline's worst accident during the decade took place in , when two Tupolev Tu-134s were involved in a mid-air collision over the Ukrainian city then named Dniprodzerzhinsk, with the loss of 178 lives. Including this event, there were nine deadly incidents with more than 100 fatalities, while the total recorded number of casualties was 3,541 for the decade. Almost all of the events shown below occurred within the Soviet Union. Certain Western media conjectured that the Soviet government was reluctant to publicly admit the occurrence of such events, which might render these figures higher, as fatal events would have only been admitted when there were foreigners aboard the crashed aircraft, the accident took place in a foreign country, or they reached the news for some reason. However, no significant amount of unreported serious accidents have emerged afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroflot Accidents And Incidents
Founded in 1923, Aeroflot, the flag carrier and largest airline of Russia (and formerly the Soviet Union) (formerly the world's largest airline), has had a high number of fatal crashes, with a total of 8,231 passengers dying in Aeroflot crashes according to the Aircraft Crashes Record Office, mostly during the Soviet-era, about five times more than any other airline. From 1946 to 1989, the carrier was involved in 721 incidents. From 1995 to 2017, the carrier was involved in 10 incidents. In 2013, AirlineRatings.com reported that five of the ten aircraft models involved in the highest numbers of fatal accidents were old Soviet models.

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.
