Lockheed L-188 Electra
The Lockheed L-188 Electra is an American turboprop airliner built by Lockheed Corporation, Lockheed. First flown in 1957, it was the first large turboprop airliner built in the United States. With its fairly high power-to-weight ratio, huge propellers and very short wings (resulting in the majority of the wingspan being enveloped in propwash), large Fowler flaps which significantly increased effective wing area when extended, and four-engined design, the airplane had airfield performance capabilities unmatched by many jet transport aircraft even today—particularly on short runways and high altitude airfields. Initial sales were good, but after two fatal crashes that led to expensive modifications to fix a design defect, no more were ordered. Jet airliners soon supplanted turboprops for many purposes, and many Electras were modified as freighters. Some Electras are still being used in various roles into the 21st century. The airframe was also used as the basis for the Lockheed P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Model 10 Electra
The Lockheed Model 10 Electra is an American twin-engined, all-metal monoplane airliner developed by the Lockheed Aircraft Corporation, which was produced primarily in the 1930s to compete with the Boeing 247 and Douglas DC-2. The type gained considerable fame after being flown by Amelia Earhart and Fred Noonan on their ill-fated around-the-world expedition in 1937. Design and development Some of Lockheed's wooden designs, such as the Lockheed Model 9 Orion, Orion, had been built by Detroit Aircraft Corporation with metal fuselages. However, the Electra was Lockheed's first all-metal and twin-engined design by Lloyd Stearman and Hall Hibbard. The name Electra (star), Electra came from a star in the Pleiades. The prototype made its first flight on February 23, 1934, with Marshall Headle at the controls. Wind-tunnel work on the Electra was undertaken at the University of Michigan. Much of the work was performed by a student assistant, Kelly_Johnson_(engineer), Kelly Johnson. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Constellation
The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943. The Constellation series was the first civil airliner family to enter widespread use equipped with a pressurized cabin, enabling it to fly well above most bad weather, thus significantly improving the general safety and ease of commercial passenger air travel. Several different models of the Constellation series were produced, although they all featured the distinctive triple-tail and dolphin-shaped fuselage. Most were powered by four 18-cylinder Wright R-3350 Duplex-Cyclones. In total, 856 were produced between 1943 and 1958 at Lockheed's plant in Burbank, California, and used as both a civil airliner and as a military and civilian cargo transport. Among their famous uses was during the Berlin Blockade#Start of the Berlin Airliftlift, Berlin and the Biafran airlifts. Three served as the presidential aircraft for Dwight D. Eisenhower, one of which is at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Civil Aeronautics Administration (United States)
The Air Commerce Act of 1926 created an Aeronautic Branch of the United States Department of Commerce. Its functions included testing and licensing of pilots, certification of aircraft and investigation of accidents. In 1934, the Aeronautics Branch was renamed the Bureau of Air Commerce, to reflect the growing importance of commercial flying. It was subsequently divided into two authorities: the Civil Aeronautics Administration (CAA), concerned with air traffic control, and the Civil Aeronautics Board (CAB), concerned with safety regulations and accident investigation. Under the Federal Aviation Act of 1958, the CAA's powers were transferred to a new independent body, the Federal Aviation Administration (FAA). In the same year, the National Aeronautics and Space Administration (NASA) was created after the Soviet Union’s launch of the first artificial satellite. The accident investigation powers of the CAB were transferred to the new National Transportation Safety Board in 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Certificate
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). Certification confirms that the aircraft of a new type intended for serial production is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, Airworthiness certificate#Special Airworthiness Certificate, primary category aircraft certification costs around US$1 million, US$25 million for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes ...

Napier Eland
The Napier Eland is a British turboshaft or turboprop gas-turbine engine built by Napier & Son in the early 1950s. Production of the Eland ceased in 1961 when the Napier company was taken over by Rolls-Royce Limited, Rolls-Royce. Design and development The Eland was first tested in flight in 1953 in a Vickers Varsity aircraft. Further flight proving was carried out from 1955 using the first production Airspeed Ambassador 2. The Eland was dropped from production when Napier was acquired by Rolls-Royce Limited in 1961. The only production applications for the engine were two variants of the Convair CV-240 family, the Royal Canadian Air Force Canadair CC-109 Cosmopolitan and the civil Convair CV-540. The military and civil operators had perpetual trouble with the engines which were considered complex. Due to their unreliability Transport Canada, The Department of Transport reduced the time between overhauls. The CC-106 had its Elands replaced with the Allison T56 turboprop and t ...

Rolls-Royce Dart
The Rolls-Royce RB.53 Dart is a turboprop engine designed and manufactured by Rolls-Royce Limited. First run in 1946, it powered the Vickers Viscount on its maiden flight in 1948. A flight on July 29 of that year, which carried 14 paying passengers between Northolt and Paris–Le Bourget Airport in a Dart-powered Viscount, was the first regularly scheduled airline flight by a turbine-powered aircraft.Turner 1968, p. 9. The Viscount was the first turboprop-powered aircraft to enter airline service - British European Airways (BEA) in 1953. The Dart was still in production forty years later when the last Fokker F27 Friendships and Hawker Siddeley HS 748s were produced in 1987. Following the company's convention for naming gas turbine engines after rivers, this turboprop engine design was named after the River Dart. History Designed in 1946 by a team led by Lionel Haworth, the Dart engine was derived using experience gained from the earlier more powerful Rolls-Royce Clyde t ...

Vickers Viscount
The Vickers Viscount is a retired British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included Cabin pressurization, pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first postwar transport aircraft; 445 Viscounts were built for a range of international customers, including in North America. Development Origins The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a postwar, small, medium-range, Cabin pressurization, pressurised aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).Cacutt 1989, pp. 323–333.
