TWA Flight 529
TWA Flight 529 was a Lockheed Constellation L-049 propliner, registration N86511, operating as a scheduled passenger service from Boston, Massachusetts to San Francisco, California. On September 1, 1961, at 02:05 CDT, the flight crashed shortly after takeoff from Midway Airport (ICAO: KMDW) in Chicago, killing all 73 passengers and five crew on board; it was at the time the deadliest single plane disaster in U.S. history. The accident was investigated by the Civil Aeronautics Board, which concluded its probable cause was the loss of a 5/16 inch bolt which fell out of the elevator control mechanism during the climb from Chicago, resulting in an abrupt pitch up followed by a stall and crash. Flight history The four-engine propliner originated in Boston, and after making intermediate stops in New York and Pittsburgh, arrived at Chicago Midway Airport at 01:18 CDT, where a new crew took over, and fuel and oil were added. At 02:00 the flight departed from runway 22, bound for L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Midway Airport
Chicago Midway International Airport , typically referred to as Midway Airport, Chicago Midway, or simply Midway, is a major commercial airport on the Southwest side of Chicago, Illinois, located approximately 12 miles (19 km) from the Loop business district. Established in 1927, Midway served as Chicago's primary airport until the opening of O'Hare International Airport in 1955. Today, Midway is one of the busiest airports in the nation and the second-busiest airport both in the Chicago metropolitan area and the state of Illinois, serving 20,844,860 passengers in 2019. Midway is a base for Southwest Airlines, which carries over 95% of the passengers at the airport. The airport's current name is in honor of the Battle of Midway. The now-defunct Midway Airlines that once serviced the airport took its name from the airport. The airfield is located in a square mile bounded by 55th and 63rd Streets, and Central and Cicero Avenues. The current terminal complex was completed ...

TWA Flight 529 Crash Site
Trans World Airlines (TWA) was a major American airline which operated from 1930 until 2001. It was formed as Transcontinental & Western Air to operate a route from New York City to Los Angeles via St. Louis, Kansas City, and other stops, with Ford Trimotors. With American, United, and Eastern, it was one of the "Big Four" domestic airlines in the United States formed by the Spoils Conference of 1930. Howard Hughes acquired control of TWA in 1939, and after World War II led the expansion of the airline to serve Europe, the Middle East, and Asia, making TWA a second unofficial flag carrier of the United States after Pan Am. Hughes gave up control in the 1960s, and the new management of TWA acquired Hilton International and Century 21 in an attempt to diversify the company's business. As the Airline Deregulation Act of 1978 led to a wave of airline failures, start-ups, and takeovers in the United States, TWA was spun off from its holding company in 1984. Carl Icahn acquired cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters. Its powers include air traffic management, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. Created in , the FAA replaced the former Civil Aeronautics Board, Civil Aeronautics Administration (CAA) and later became an agency within the United States Department of Transportation, U.S. Department of Transportation. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and developing civil aeronautics, ...

Hydraulic Drive System
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes. Hydraulic systems, like pneumatic systems, are based on Pascal's law which states that any pressure applied to a fluid inside a closed system will transmit that pressure equally everywhere and in all directions. A hydraulic system uses an incompressible liquid as its fluid, rather than a compressible gas. The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, the high power density and a wide array of actuators that can make use of this power, and the huge multiplication of force ...

Stall (flight)
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 propel ...

Flight Dynamics
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft. Spacecraft flight dynamics involve three main forces: propulsive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and the ...
