Matteson M-1
The Matteson M-1 was an American high-wing, single-seat, FAI Open Class Glider (sailplane), glider that was designed and built by Fred Matteson of Palo Alto, California and Alfred Vogt (glider designer), Alfred Vogt of Schempp-Hirth. Design and development Work on the M-1 started in 1955 at the Schempp-Hirth factory, while Matteson was on military duty in West Germany. The design that Matteson had conceived was adapted to German metric standards and materials by Alfred Vogt who did the early construction work. After being posted back to the United States Matteson completed the aircraft in 1959 in California. The M-1 was built from wood and covered with doped aircraft fabric covering. The semi-tapered wing was of span and used a NACA 63-518 wing root airfoil, transitioning to a NACA 4412 airfoil at the wing tip. The three-piece wing, with a fixed center section and removable tips, featured a foam-filled leading edge and large-sized lower surface dive brakes. The aircraft had a ...

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 ...

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...

1950s United States Sailplanes
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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.

Martin M-1
The Martin M-1 was an American gull winged, single-seat glider that was designed and built by Volmer Jensen in 1939.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 48. Soaring Society of America November 1983. USPS 499-920 Design and development Jim Martin contracted Jensen to design and built him a glider for contest flying just before the Second World War. Jensen completed the aircraft in 1939. The aircraft was constructed with a wooden structure and covered in doped aircraft fabric covering. The cantilever gull-style wing employed a NACA 4400 series airfoil. The tail was a conventional low-tail design and featured strut-bracing. The M-1 was registered as an ''Experimental - Amateur-built'' aircraft and was not type certified. Operational history Martin flew the aircraft in a number of US Nationals, as did a later owner of the M-1, Emil Lehecka. While Lehecka owned it the aircraft picked up the nickname of the ''Whatsit''. By the 1970s the aircraft was owned ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters.

Yuba City, California
Yuba City (Maidu: ''Yubu'') is a city in Northern California and the county seat of Sutter County, California, United States. The population was 70,117 at the 2020 census. Yuba City is the principal city of the Yuba City Metropolitan Statistical Area which encompasses all of Sutter County and Yuba County. The metro area's population is 164,138.

One version of the origin of the name "Yuba" is that during one of these expeditions, wild grapes were seen growing by a river, and so it was named "Uba", a variant spelling of the Spanish word ''uva'' (grape). The Mexican government granted a large expanse of land, which included the area in which Yuba City ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
