RB-26 Invader
The Douglas A-26 Invader (designated B-26 between 1948 and 1965) is an American twin-engined light bomber and ground attack aircraft. Built by Douglas Aircraft Company during World War II, the Invader also saw service during several major Cold War conflicts. A limited number of highly modified United States Air Force aircraft served in Southeast Asia until 1969. It was a fast aircraft capable of carrying a large bomb load. A range of guns could be fitted to produce a formidable ground-attack aircraft.Wheeler 1992, p. 82. A redesignation of the type from A-26 to B-26 has led to confusion with the earlier and unrelated Martin B-26 Marauder, which had already been withdrawn from service when the designation was reused. Design and development The A-26 was Douglas Aircraft's successor to the A-20 (DB-7) Havoc, also known as Douglas Boston. Designed by Ed Heinemann, Robert Donovan, and Ted R. Smith,Francillon 1979 the innovative NACA 65-215 laminar-flow airfoil wing of the A-26 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual, the aircraft would often stall and crash.Ethell 1995, p. ...

Propeller (aircraft)
In aeronautics, an aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cowling
A cowling (or cowl) is the removable covering of a vehicle's engine, most often found on automobiles, motorcycles, airplanes, and on outboard boat motors. On airplanes, cowlings are used to reduce drag and to cool the engine. On boats, cowlings are a cover for an outboard motor. In addition to protecting the engine, outboard motor cowlings need to admit air while keeping water out of the air intake. Etymology "Cowling" comes from "cowl", which originated from Middle English coule, from Old English cūle, from earlier cugele (“hood, cowl”). This, in turn, came from Ecclesiastical Latin cuculla (“monk's cowl”), from Latin cucullus (“hood”), of uncertain origin. In aviation In aviation, a cowling may be used for drag reduction or engine cooling by directing airflow. Examples in aviation include the NACA cowling and Townend ring. On an airplane, the cowling may also cover part of the fuselage, the nacelles, the engine mount and part of the cockpit.Aviation Machinist's Ma ...

Ben Howard (aviator)
Benjamin Odell Howard (February 4, 1904 – December 4, 1970), was an American aviator and aeronautical engineer, whose aircraft won the Bendix Trophy and the Thompson Trophy in 1935.Benny Howard and His Darned Good Airplanes History At 17 Howard's interest in flying was sparked when he saw a band of gypsy fliers performing in their flying circus. By 18 he had saved up enough cash to buy an OX-5 powered Standard biplane. In those days learning how to fly was often self-taught and Howard thought he was up to it. The Standard was a safe plan ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Segundo, California
El Segundo ( , ; ) is a city in Los Angeles County, California, United States. Located on Santa Monica Bay, it was incorporated on January 18, 1917, and is part of the South Bay Cities Council of Governments. The population was 17,272 as of the 2020 census, a 3.7% increase from 16,654 in the 2010 census. A significant center of the oil and aerospace industries in Southern California, roughly three quarters of the city's land is dedicated exclusively to industrial and commercial uses, including a Chevron oil refinery which alone takes up more than a quarter of the entire city. History The El Segundo and Los Angeles coastal area was first settled by the Tongva (or Gabrieleños) Native American tribes. The area was once a part of '' Rancho Sausal Redondo'' ("Round Willow Patch Ranch"). Rancho Sausal Redondo extended from Playa Del Rey in the north to Redondo Beach in the south. Originally a Mexican land grant owned by Antonio Ygnacio Avila, the rancho was later purchased by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
