Helikopter Service Flight 165
Helikopter Service Flight 165 was a crash of a Sikorsky S-61 helicopter into the North Sea, northwest of Bergen, Norway, on 26 June 1978. The aircraft was en route from Bergen Airport, Flesland to Statfjord A, an offshore oil platform. The accident was caused by a fatigue crack in a knuckle joint, causing one of the rotor blades to loosen. All eighteen people on board were killed in the crash. Aircraft The helicopter involved in the crash was a 2-year old Sikorsky S-61 The Sikorsky S-61L and S-61N are civil variants of the Sikorsky SH-3 Sea King, SH-3 Sea King military helicopter.

Structural Failure
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. Items are constructed with structural integrity to prevent catastrophic failure, which can result in injuries, severe damage, death, and/or monetary losses. ''Structural failure'' refers to the loss of structural integrity, or the loss of load-carrying structural capacity in either a structural component or the structure itself. Structural failure is ...

Helicopter Rotor
On a helicopter, the main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift (force), lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. Each main rotor is mounted on a vertical mast over the top of the helicopter, as opposed to a helicopter tail rotor, which connects through a combination of drive shaft(s) and gearboxes along the tail boom. The blade pitch is typically controlled by the pilot using the helicopter flight controls. Helicopters are one example of rotary-wing aircraft (rotorcraft). The name is derived from the Greek words ''helix'', helik-, meaning spiral; and ''pteron'' meaning wing. Design principles Overview The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airliner Accidents And Incidents Caused By In-flight Structural Failure
An airliner is a type of airplane for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a long, tube shaped, and jet powered aircraft. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major carriers, legacy carriers, and flag carriers, and are used to feed traffic into the large airline ...

Aviation Accidents And Incidents In The North Sea
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft 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. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the ''Wright Flyer'', 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 engine which enabled aviation ...

Accidents And Incidents Involving The Sikorsky S-61
An accident is an unintended, normally unwanted event that was not deliberately caused by humans. The term ''accident'' implies that the event may have been caused by unrecognized or unaddressed risks. Many researchers, insurers and attorneys who specialize in unintentional injury prefer to avoid using the term ''accident'', and focus on conditions that increase risk of severe injury or that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been directly caused by human error, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car crashes are the result of dangerous behavior and not purely ''accidents''; however, English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Accidental deaths were much less frequent before high-powered machinery began to spread with the Industrial Revolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knuckle Joint (mechanical)
The knuckles are the joints of the fingers. The word is cognate to similar words in other Germanic languages, such as the Dutch "knokkel" (knuckle) or German "Knöchel" (ankle), i.e., ''Knöchlein'', the diminutive of the German word for bone (''Knochen''). Anatomically, it is said that the knuckles consist of the metacarpophalangealUtah Mountain BikingThumb Sprain First as metacarpo. (MCP) and interphalangeal (IP) joints of the finger. The knuckles at the base of the fingers may be referred to as the 1st or major knuckles while the knuckles at the midfinger are known as the 2nd and 3rd, or minor, knuckles. However, the ordinal terms are used inconsistently and may refer to any of the knuckles. Cracking The physical mechanism behind the popping or cracking sound heard when cracking joints such as knuckles was elucidated in 2015 by cine MRI to be caused by tribonucleation as a gas bubble forms in the synovial fluid that bathes the joint.
