Douglas XA2D-1
The Douglas A2D Skyshark is an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy. The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out. Design and development On 25 June 1945, the Bureau of Aeronautics (BuAer) asked Douglas Aircraft for a turboprop-driven aircraft. Three proposals were put forth in the next year and a half: the D-557A, to use two General Electric TG-100s (T31s) in wing nacelles; the D-557B, the same engine, with contra-rotating propellers; and the D-557C, to use the Westinghouse 25D. These were canceled due to engine development difficulties, but BuAer continued to seek an answer to the high fuel-consumption of jet aircraft.Francillon 1988, p. 441. On 11 June 1947 Douglas received the Navy's letter of intent for a car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Allison XT40-A-2
The Allison T40, company designation Allison Model 500, was an early American turboprop engine composed of two Allison T38 power sections driving a contra-rotating propeller via a common gearbox. Design and development The T40 concept originated at Allison in 1944, where design studies were carried out on a turboprop engine. Taking advantage of this effort, the US Navy awarded Allison a contract for the design and development of a turboprop engine. The resulting T40 combined two Allison T38-A-1 power sections side-by-side with a common reduction gearbox powering contra-rotating propellers. Similar in layout to the Armstrong Siddeley Double Mamba, the T40 differed in that each engine drove both the forward and the rear propellers, unlike the Double Mamba, where each Mamba power section drove either the front or the rear propeller separately. The T38-A-1 power sections each contained 17-stage compressors giving a pressure ratio of 6.3:1, eight combustion chambers, and four-sta ...

NACA Airfoil
The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum Camber (aerodynamics), camber as percentage of the Chord (aircraft), chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thick ...

Gillespie Field is a county-owned public airport in El Cajon, California. It is located 11.5 miles (18.5 km; 10 nmi) northeast of downtown San Diego. History : ''Section reference dates.'' In 1942 the United States Marine Corps chose a site with east of San Diego for parachute training for the newly forming Paramarines, parachute battalions. In September 1942, Camp Gillespie was completed and named in honor of Lieutenant Archibald H. Gillespie, a Marine officer who played a prominent role in the effort to separate California from Mexico in the 1840s. Three high towers were built from which the paratroopers practiced their jumps. In February 1944, the camp was commissioned as Marine Corps Auxiliary Airfield Gillespie under the command of Marine Corps Air Station El Toro. MCAAF Gillespie soon became responsible for Marine Corps Air Station Camp Pendleton, Camp Pendleton Outlying Air Field.

Douglas A-4 Skyhawk
The Douglas A-4 Skyhawk is a single-seat subsonic carrier-capable light attack aircraft designed and produced by the American aerospace manufacturer Douglas Aircraft Company, and later, McDonnell Douglas. It was originally designated A4D under the United States Navy's pre-1962 designation system. The Skyhawk was developed during the early 1950s on behalf of the Navy and United States Marine Corps as a replacement for the propeller-driven Douglas A-1 (AD) Skyraider. The A-4 is a compact, straightforward, and lightweight aircraft for the era; its maximum takeoff weight of was roughly half of the Navy's weight specification. The Skyhawk has a short-span delta wing configuration, a tricycle undercarriage, and is powered by a single turbojet engine. The U.S. Navy issued a contract for the aircraft on 12 June 1952. On 22 June 1954, the XA4D-1 prototype performed its maiden flight; it went on to set a world speed record of 695.163 mph on 15 October 1955. On 1 October 1956, ...

George Jansen
George Jansen was a test pilot during the golden age of flight test at Edwards Air Force Base from the late 1940s through the 1950s. He not only flew as test pilot for many experimental planes such as the Douglas A2D Skyshark but also flew drop planes such as the B-29 Superfortress for other flight tests such as carrying the Douglas D-558-2 Skyrocket piloted by Bill Bridgeman. Born in Willows, California in 1921, he learned to fly crop dusting planes at the Nolta Air Service. In 1941 he entered the Army Air Corps. Jansen flew B-24 Liberators from England during World War II including the famous Ploesti Raid. After the war he Joined Douglas Aircraft Co. as a test pilot, flying many aircraft including the A2D, A3D, B-66 and the B-29 drop plane for the rocket powered Douglas D-558-II Skyrocket, which set an altitude record of over 79,000 ft. at a speed of Mach 1.4.

Wright R-3350 Duplex-Cyclone
The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly . Power ranged from , depending on model. Developed before World War II, the R-3350's design required a long time to mature, and was still experiencing problems with reliability when used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to be used in many civilian airliners, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1950s. Its main rival was the , Pratt & Whitney R-4360 Wasp Major, which first ran some seven years after the Duplex-Cyclone. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Design and development In 1927, Wright Aeronautical introduced its "Cyclone" engine, which powered a number of designs in the 1930s. After merging with Curtiss to become ...
