Aeroflot Flight 68
Aeroflot Flight 068 was a regularly scheduled passenger flight operated by Aeroflot from Khabarovsk Novy Airport in Khabarovsk Krai to Pulkovo Airport in Saint Petersburg with intermediate stops at Tolmachevo Airport in Ob, Russia, then Koltsovo Airport in Yekaterinburg. On 16 March 1961, the Tupolev Tu-104B operating this flight crashed shortly after take off from Koltsovo Airport. Three passengers and two crewmembers were killed along with two people on the ground. The Air Accident Investigation Commission concluded the cause of the accident was the failure of engine No. 2 (right) due a broken turbine blade. Accident After takeoff from Koltsovo Airport while climbing though altitude as the crew reduced the engine power from takeoff setting, engine No. 2 began vibrating severely. The crew was uncertain which engine was failing and were unable to use the engine instruments because the instrument panel was vibrating violently. A crew member decided to reduce power on eng ...

Turbine Engine Failure
A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles. Reliability Turbine engines in use on today's turbine-powered aircraft are very reliable. Engines operate efficiently with regularly scheduled inspections and maintenance. These units can have lives ranging in the thousands of hours of operation. However, engine malfunctions or failures occasionally occur that require an engine to be shut down in flight. Since multi-engine airplanes are designed to fly with one engine inoperative and flight crews are trained to fly with one engine inoperative, the in-flight shutdown of an engine typically does not constitute a serious safety of flight issue. The Federal Aviation Administration (FAA) was quoted as stating turbine engines have a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flap (aeronautics)
A flap is a high-lift device used to reduce the stall (flight), stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in Drag (physics), drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the Stall (fluid dynamics), stall of the outboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accidents And Incidents Involving The Tupolev Tu-104
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 ...

Aviation Accidents And Incidents In 1951
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 ...

TransAsia Airways Flight 235
TransAsia Airways Flight 235 was a TransAsia Airways domestic flight from Taipei to Kinmen (Quemoy). On , the aircraft serving the flight, a 10-month-old ATR 72-600, crashed into the Keelung River shortly after takeoff from Taipei Songshan Airport, to the east of Songshan in Taiwan. The aircraft had 53 passengers and five crew on board; 15 of them survived. Two minutes after takeoff, the pilots reported an engine flameout. Flight 235 climbed to a maximum height of , then descended. The other engine, still working, was shut down mistakenly. Immediately before crashing into the river, it banked sharply left and clipped a taxi travelling west on the Huandong Viaduct (causing two more injuries), then the viaduct itself, with its left wing. Flight 235 was the second fatal accident involving a TransAsia Airways ATR aircraft within seven months; Flight 222 had crashed on 2014, killing 48 of the 58 onboard.

Kegworth Air Disaster
The Kegworth air disaster occurred when British Midland Airways Flight 092, a Boeing 737-400, crashed onto the motorway embankment between the M1 motorway and A453 road near Kegworth, Leicestershire, England, while attempting to make an emergency landing at East Midlands Airport on 8 January 1989. The aircraft was on a scheduled flight from London Heathrow Airport to Belfast International Airport when a fan blade broke in the left engine, disrupting the air conditioning and filling the cabin with smoke. The pilots believed this indicated a fault in the right engine, since earlier models of the 737 ventilated the cabin from the right, and they were unaware that the 737-400 used a different system. The pilots mistakenly shut down the functioning engine. They selected full thrust from the malfunctioning one and this increased its fuel supply, causing it to catch fire. Of the 126 people aboard, 47 died and 74 sustained serious injuries. The inquiry attributed the blade fracture to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fatigue (material)
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting t ...
