Mitchell Nimbus
The Mitchell Nimbus is a series of American, single-seat, high-wing gliders that was designed by Don Mitchell in the 1950s. Mitchell is also well known for his ultralight Mitchell Wing A-10 and U-2 designs.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 15. Soaring Society of America, November 1983. USPS 499-920 Design and development The Nimbus series was designed as an attempt to combine a high aspect ratio wing with a thin airfoil section to produce a fast cross country sailplane. The first Nimbus prototype used a Göttingen airfoil, which resulted in lower than expected performance. It first flew in 1954. The Nimbus III, introduced in 1956, employed an FX-05-191 airfoil and this greatly improved performance. The Nimbus III is constructed entirely from wood and incorporates a three-piece wing, with a center section and removable wing tips. Rib spacing is 6 inches and the plywood leading edge extends to 83% of the chord. Operational history The origina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wing Tip
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: * Squared-off * Aluminium tube bow * Rounded * Hoerner style * Winglets * Drooped tips * Raked wingtips * Tip tanks * Sails * Fences * End plates Winglets have become popular additions to high speed aircraft to increase fuel efficiency by reducing drag from wingtip vortices. In lower speed aircraft, the effect of the wingtip shape is less apparent, with only a marginal performance difference between round, square, and Hoerner style tips The slowest speed aircraft, STOL aircraft, may use wingtips to shape airflow for controllability at low airspeeds. Wing tips are also an expression of aircraft design style, so their shape may be influenced by marketing considerations as well as by aerodynamic requirements. Wing tips are ...

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.

National Soaring Museum
The National Soaring Museum (NSM) is an aviation museum whose stated aim is to preserve the history of motorless flight. It is located on top of Harris Hill near Elmira, New York, United States. The NSM is the Soaring Society of America's official repository. In 1975, the SSA Board of Directors transferred the Soaring Hall of Fame to the National Soaring Museum. The museum features a large collection of vintage and historical gliders. The museum also administers the National Landmark of Soaring program to recognize people, places and events which are significant in the history of motorless aviation. History Elmira and Harris Hill have long been associated with soaring in the USA. The establishment of the nation's most prolific glider manufacturer, Schweizer Aircraft in Elmira and the holding of first 13 National Soaring Contests at the site between 1930 and 1946 guaranteed its stature as a location. During the US National Soaring Contests in the 1950s competitors and organizer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
