Llandow Air Disaster
The Llandow air disaster was an aircraft accident in Wales in 1950. At that time it was the world's worst air disaster with a total of 80 fatalities. The aircraft, an Avro Tudor V, had been privately hired to fly rugby union enthusiasts to and from an international game in Ireland. On the return flight the aircraft stalled and crashed on its approach to land. Course of events On 12 March 1950, an Avro 689 Tudor V, ''Star Girl'', owned by Airflight Limited and being operated under the "Fairflight" name, took off from Dublin Airport in Ireland, on a private passenger flight to Llandow aerodrome in South Wales. The aircraft had 78 passengers and 5 crew on the manifest. The flight had been chartered privately for a trip to Belfast to watch the Welsh rugby union team compete against the Irish in the Five Nations Championship at the Ravenhill Stadium. The aircraft had been initially booked for 72 passengers, but the plane had been stripped to accommodate another six. The wea ...

Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thr ...

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] |
Moses Lake, Washington
Moses Lake is a city in Grant County, Washington, United States. The population was 25,146 as of the 2020 census. Moses Lake is the largest city in Grant County. The city anchors the Moses Lake Micropolitan area, which includes all of Grant County and is part of the Moses Lake–Othello combined statistical area. Moses Lake, on which the city lies, is made up of three main arms over long and up to one mile (1.6 km) wide. It is the largest natural body of fresh water in Grant County and has over of shoreline covering . Before it was dammed in the early 1900s and then incorporated into the Columbia Basin Project, Moses Lake was a smaller shallow lake. To the south of the town is the Potholes Reservoir and the Columbia National Wildlife Refuge that has a number of seep lakes and vast amounts of migratory birds and other fauna natural to the area. History Before the construction of Grand Coulee Dam on the Columbia River in 1941 and Moses Lake Army Air Base in 1942 the a ...

1952 Moses Lake C-124 Crash
The 1952 Moses Lake C-124 crash was an accident in which a United States Air Force Douglas C-124 Globemaster II military transport aircraft crashed near Moses Lake, Washington on December 20, 1952. Of the 115 people on board, 87 died and 28 survived. The crash was the world's deadliest aviation disaster at the time, surpassing the Llandow air disaster, which killed 80 people. The death toll would not be surpassed until the Tachikawa air disaster, which also involved a Douglas C-124A-DL Globemaster II, killed 129 people. Accident The flight was part of "Operation: Sleigh Ride", a USAF airlift program to bring U.S. servicemen fighting in the Korean War home for Christmas. At around 18:30 PST, the C-124 lifted off from Larson Air Force Base near Moses Lake, Washington en route to Kelly Air Force Base, San Antonio, Texas. Just seconds after taking off, the left wing struck the ground and the aircraft cartwheeled, broke up, and exploded, killing 82 of the 105 passengers and 5 of t ...

Douglas C-124 Globemaster II
The Douglas C-124 Globemaster II, nicknamed "Old Shaky", is an American heavy-lift cargo aircraft built by the Douglas Aircraft Company in Long Beach, California. The C-124 was the primary heavy-lift transport for United States Air Force (USAF) Military Air Transport Service (MATS) during the 1950s and early 1960s, until the Lockheed C-141 Starlifter entered service. It served in MATS, later Military Airlift Command (MAC), units of the Air Force Reserve and Air National Guard until retired in 1974. Design and development Douglas Aircraft developed the C-124 from 1947 to 1949, from a prototype they created from a World War II–design Douglas C-74 Globemaster, and based on lessons learned during the Berlin Airlift. The aircraft was powered by four large Pratt & Whitney R-4360 Wasp Major piston engines producing each. The C-124's design featured two large clamshell doors and a hydraulically actuated ramp in the nose as well as a cargo elevator under the aft fuselage. The C-124 ...

USS Akron (ZRS-4)
USS ''Akron'' (ZRS-4) was a helium-filled rigid airship of the U.S. Navy, the lead ship of her class, which operated between September 1931 and April 1933. It was the world's first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes, which could be launched and recovered while it was in flight. With an overall length of , ''Akron'' and her sister ship were among the largest flying objects ever built. Although LZ 129 ''Hindenburg'' and LZ 130 '' Graf Zeppelin II'' were some longer and slightly more voluminous, the two German airships were filled with hydrogen, and so the two US Navy craft still hold the world record for the largest helium-filled airships. ''Akron'' was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. The accident involved the greatest loss of life in any airship crash. Technical description The airship's skeleton was built of the new lightw ...

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
