Douglas A2D Skyshark
The Douglas A2D Skyshark was 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 counter-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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. 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 as percentage of the 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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gillespie Field
Gillespie Field is a county-owned public towered airport northeast of downtown San Diego, in El Cajon, San Diego County, California, United States. 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 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 Camp Pendleton Outlying Air Field.

Douglas A-4 Skyhawk
The Douglas A-4 Skyhawk is a single-seat subsonic carrier-capable light attack aircraft developed for the United States Navy and United States Marine Corps in the early 1950s. The delta-winged, single turbojet engined Skyhawk was designed and produced by Douglas Aircraft Company, and later by McDonnell Douglas. It was originally designated A4D under the U.S. Navy's pre-1962 designation system. The Skyhawk is a relatively light aircraft, with a maximum takeoff weight of , and has a top speed of . The aircraft's five hardpoints support a variety of missiles, bombs, and other munitions. It is capable of carrying a bomb load equivalent to that of a World War II–era Boeing B-17 bomber, and can deliver nuclear weapons using a low-altitude bombing system and a "loft" delivery technique. The A-4 was originally powered by the Wright J65 turbojet engine; from the A-4E onwards, the Pratt & Whitney J52 engine was used. Skyhawks played key roles in the Vietnam War, the Yom Kippur ...

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. He later became the head of flight test for Douglas Aircraft and flew the maiden flights of commercial aircraft like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contra-rotating Propeller
Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive a pair of coaxial propellers in contra-rotation. Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission. Contra-rotating propellers are also known as counter-rotating propellers, although counter-rotating propellers is much more widely used when referring to airscrews on separate non-coaxial shafts turning in opposite directions. Operation When airspeed is low, the mass of the air flowing through the propeller disk (thrust) causes a significant amount of tangential or rotational air flow to be created by the spinning blades. The energy of this tangential air flow is wasted in a single-propeller design, and causes handling problems at low speed as the air strikes the vertical sta ...

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 2,200 to over 3,700 hp (1,640 to 2,760 kW), depending on the model. Developed before World War II, the R-3350's design required a long time to mature before finally being used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to become a major civilian airliner design, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1990s. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Its main rival was the , Pratt & Whitney R-4360 Wasp Major, first run some seven years after the Duplex-Cyclone's beginnings. Design and development In 1927, Wright Aeronautical introduced its famous "Cyclone" engine, which powered a number of designs in the 1930s. ...
