Schweizer SGU 1-19
The Schweizer SGU 1-19 and Schweizer SGU 1-20 are a family of United States single-seat, high-wing, strut-braced, utility gliders built by Schweizer Aircraft of Elmira, New York.Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', pages 96-108. Smithsonian Institution Press, 1988. The 1-19 was a 1944 development of the pre-war SGU 1-7 and bears a strong resemblance to the earlier craft. It was designed for single place training and soaring flights. The 1-20 was an improved version of the 1-19 with a wingspan of replacing the wing on the 1-19. Background Schweizer Aircraft had produced the SGS 2-8 and SGS 2-12 training gliders for the US military as well as producing many aircraft parts under subcontract for the war effort. As the Second World War was drawing to a close the company decided to continue to make gliding part of their business plan. Many economic forecasts had predicted a post war aviation boom, with thousands of military tr ... [...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".

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s United States Sailplanes
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

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] |
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] |

Motorglider
A motor glider is a fixed-wing aircraft that can be flown with or without engine power. The FAI Gliding Commission Sporting Code definition is: a fixed-wing aerodyne equipped with a means of propulsion (MoP), capable of sustained soaring flight without thrust from the means of propulsion. History In 1935, an occasional or auxiliary motor that could be retracted was suggested by Sir John Carden. This was incorporated into the Carden-Baynes Auxiliary that first flew on 8 August of the same year. A later version of the Budig glider was powered. Types Most motor gliders are equipped with a propeller, which may be fixed, feathered (e.g. AMS-Flight Carat), or retractable. However jet engine-powered motorgliders are now available from some manufacturers, some of which are intended for use only as "sustainer" engines, i.e. for sustaining gliding flight rather than as self-launching aircraft.

Cayuta, New York
Cayuta is a city in Schuyler County, New York, United States. As of the 2020 census, the population was 508. The City of Cayuta occupies the southeastern corner of the county and is northeast of Elmira. It is part of the Elmira Metropolitan Statistical Area. History The first pioneers arrived ''circa'' 1798 near the community of Cayuta. The town was created from part of the Town of Spencer ( Tioga County) in 1824, before the formation of Schuyler County. The size was increased in 1854 by the addition of parts of two other towns: Catharine and Erin (then both in Chemung County). In the same year, Schuyler County was created, and Cayuta was included in the new county. Geography According to the United States Census Bureau, the town has a total area of , all land. The western, southern and eastern town lines border Chemung County, and the northern town line borders primarily Tompkins County.

Schweizer SGM 2-37
The Schweizer SGM 2-37 is a two-place, side-by-side, fixed gear, low wing motor glider.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 131. Soaring Society of America, November 1983. USPS 499–920 A total of twelve were produced between 1982 and 1988, including nine for the United States Air Force Academy, which designated it the TG-7A. The TG-7A was retired from USAFA service in April 2003. The basic airframe was later developed into the SA 2-37A and B covert surveillance aircraft. Development Schweizer had flown a Schweizer SGU 1-19 as a motor glider in 1946 without putting the design into production. In 1958 the company carried out a design study of a powered aircraft using the wings and tail of the 1-26 designated as the Schweizer SA 1-30, but after some test flying and modification it was not put into production. A two-seat version of the 1-30, the Schweizer SA 2-31 was completed in 1960 but not put into production due to competition in the light aircraf ...

Ground Effect (aircraft)
For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface.. Reduced drag when in ground effect during takeoff can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached.. For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At high weights this sometimes allows the rotorcraft to lift off while stationary in ground effect but does not allow it to transition to flight out of ground effect. Helicopter pilots are provided with performance charts which show the limitations for hovering their helicopter in ground effect (IGE) and out of ground effect (OGE). The charts show the added lift benefit produced by ground effect. For fan- and jet-powered vertical take-off and landing (VTOL) aircraft, ground effect when ...

Schweizer Brothers
Paul, William (Bill), and Ernest Schweizer were three brothers who started building gliders in 1930. In 1937, they formed the Schweizer Metal Aircraft Company. Their first commercial glider sale was an Schweizer SGU 1-7, SGU 1-7 Glider (sailplane), glider to Harvard University's Altosaurus Glider Club. At that time, Eliot Noyes was a sailplane Aviator, pilot in the Harvard soaring club. That glider was later restored and currently resides at the National Soaring Museum in Elmira, New York. In 1939, the Schweizer brothers relocated to Elmira, New York, and incorporated as Schweizer Aircraft. Best known internationally for their gliders, they also remembered the importance of the folks who worked with them and for them. Over their nearly 70 years, they enabled creation of various flying machines; from gliders to Agricultural aircraft, crop dusters to helicopters, while contributing to the aircraft industry as a whole, and the Southern Tier of New York in particular.
