Vogt Lo-150
The Vogt Lo-150 is a West German high-wing, single seat glider that was designed by Alfred Vogt and produced by the Wolf Hirth Company.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 91, Soaring Society of America November 1983. USPS 499-920 Design and development The Lo-150 was developed from the wing span aerobatic Vogt Lo-100 as a performance cross country sailplane. The Lo-150 is constructed from wood, including its wooden monocoque fuselage. Its span two-piece wing employs a Clark Y airfoil and incorporates flaps for glidepath control. Early examples use a take-off dolly and land on a fixed skid, while later ones use a fixed monowheel landing gear. Fifteen Lo-150s were produced. Operational history Several Lo-150s were imported into the United States. A.J. Smith won the US Nationals flying an Lo-150 in 1961. Harold Jensen flew an Lo-150 in 1962, winning the Barringer Trophy.

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archive
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schweizer SGS 1-23
The Schweizer SGS 1-23 is a United States Open and Standard Class, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. The original "standard" 1-23 was introduced in 1948. The aircraft quickly became the most numerous competition and performance sailplane in the USA. A total of 93 of all sub-models were built by the time production was completed in 1967. Design and development Schweizer Aircraft started construction of the 1-23 prototype in May 1948. The aircraft was completed and first flew on 5 July 1948, only nine weeks after construction had begun. The prototype had been ordered by Bill Frutchy of Elmira, New York and the aircraft was available for him to fly it in the second half of the US Nationals. The first production 1-23 was ordered by E.J Reeves. The success of this aircraft led to more orders and series production was commenced. The 1-23 was initially sold on a "factory direct" basis, which allowed them to be sold at a lower price than thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barringer Trophy
The Lewin B. Barringer Memorial Trophy was established by the will of Lewin Barringer in 1948. The original rules specified that the trophy would be awarded for the longest distance soaring flight from any type of launching method other than airplane tow. The trophy would become the permanent property of any pilot who won it three times in succession. History Paul Bikle was the first pilot to win the Trophy three times in succession. He subsequently donated the trophy back to the Soaring Society of America as a perpetual trophy. In 1957 the SSA Directors, with Bikle's approval, changed the rules to allow for any type of launch method and include any flights, other than those flown at the US National Contest. Recipients Recipients of this trophy, from 1948 to present, include: See also * List of aviation awards This list of aviation awards is an index to articles about notable awards given in the field of aviation.

Harold Jensen (glider Pilot)
Harold Jensen (born c. 1965) is an American former basketball player. He is best remembered as a key player in Villanova University's surprise 1985 NCAA championship victory. He shot the winning basket in the final minutes of the 1985 showdown against Georgetown. Jensen was a 6'4" swingman from Trumbull High School in Trumbull, Connecticut. He played for coach Rollie Massimino at Villanova from 1983 to 1987. Jensen played little as a freshman, but as a sophomore was the sixth man for the Wildcats' 1985 National Championship team. For the season, Jensen averaged 4.1 points per game, but he came off the bench in the 1985 NCAA title game to shoot a perfect 5–5 from the floor and hit four clutch free throws in the closing minutes as Villanova beat the defending champion Georgetown Hoyas 66–64 in what is considered by many to be one of the biggest upsets in sports history. Jensen was named to the All-tournament team for his performance and would be remembered as one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduc ...

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 th ...

Clark Y
Clark Y is the name of a particular airfoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in 1922 by Virginius E. Clark using thickness distribution of the German-developed Goettingen 398 airfoil.Piccirillo, Albert, "The Clark Y Airfoil - A Historical Retrospective," SAE/AIAA paper 2000-01-5517, presented at the World Aviation Congress & Exposition, October 10, 2000, San Diego, California. The airfoil has a thickness of 11.7 percent and is flat on the lower surface aft of 30 percent of Chord (aircraft), chord. The flat bottom simplifies angle measurements on propellers, and makes for easy construction of wings. For many applications the Clark Y has been an adequate airfoil section; it gives reasonable overall performance in respect of its lift-to-drag ratio, and has gentle and relatively benign Stall (flight), stall characteristics. But the flat lower surface is not optimal from an aerodynamic pers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whic ...
