Harlow PJC-2
The Harlow PJC-2 was a 1930s American four-seat cabin monoplane, designed by Max Harlow. Development Max Harlow was an aeronautical engineer and instructor at the Pasadena Junior College. Under his tutelage, the aircraft designated PJC-1 was designed and built as a class project. The PJC-1 first flew on 14 September 1937 at Alhambra, California but it crashed during an extended (more than six turn) spin test with the center of gravity ballasted to the aft limit, as it was going through the certification process—a problem generally laid at the feet the unusually rigorous spin test requirement and the government test pilot, who bailed out of the airplane after the spin "flattened out." The airplane struck the ground, still in the "flat" (longitudinally level) attitude in a bean field near Mines Field (now Los Angeles International Airport) with considerable damage; although repairable, the PJC-1 was never returned to service. PJC students then built a slightly modified airpla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1930s United States Civil Utility Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Warren CP-1
The Warren CP-1, also called Miss Poly, Miss Polytechnic and the Warren Monoplane, was the second aircraft built by engineering students at California Polytechnic State University, California Polytechnic College, after their first project the Mason Greater Meteor. Design and development The CP-1 was built for Cal Poly instructor Martin C. Martinsen and completed in August 1929. It was a high-wing conventional landing gear equipped monoplane using dual airfoil-shaped lift struts. The fuselage is made of fabric-covered welded steel tubing, with wooden wing spars and ribs. The red, yellow and blue paint scheme was taken a from an earlier Berrylold Paint advertisement. An exhaust collector ring, larger rudder and low-pressure wheels and tires were added after construction. Operational history The CP-1 was licensed as an experimental aircraft and test flown from E.W. Clark Field in September 1929. It won a silver cup and two blue ribbons at the California State Fair, and on 29 June 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Globe Swift
The Globe GC-1 Swift, also known as the Globe/Temco Swift, is a light, two-seat sport monoplane from the post-World War II period. Design and development The Swift was designed by R.S. "Pop" Johnson in 1940, despite the fanciful story which has now entered into popular mythology surrounding the Swift's origin (that a Culver Cadet was obtained as a "template" aircraft). The design was financially secured by John Kennedy, president of the Globe Medicine Company, to be built by his new Globe Aircraft Company. World War II interrupted their plans, however, and the GC-1A Swift advertised as the "All Metal Swift" re-designed by K.H."Bud" Knox, received its type certificate on 7 May 1946. Two prototypes were built but essentially, the design remained the same as the type entered production. Globe built about 408 GC-1As. Later that year, the Swift received a more powerful engine of , making it the GC-1B. Globe, together with TEMCO, built 833 GC-1Bs in six months. Globe's producti ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
