Scheibe SF-23 Sperling
The Scheibe SF-23 Sperling ( en:Sparrow) is a 1950s German two-seat cabin monoplane. Development The Sperling was the first design of powered aircraft to come from the Scheibe Flugzeugbau company which had started building gliders in 1951. The prototype first flew on 8 August 1955 and the initial production SF-23A aircraft first flew in September 1958. The Sperling is a high-wing braced monoplane with side-by-side seating for two in an enclosed cabin. It had a fixed tailwheel landing gear and was initially powered by a Continental C90 piston engine. The Sperling utilizes mixed construction, the fuselage being a fabric-covered steel-tube structure and the wings being single-spar wooden structures with fabric and plywood covering. Production of the Sperling was completed in 1963. Operation Most aircraft produced were sold to German private pilots and flying clubs but one was purchased by a British owner. The higher powered versions were suitable for use in glider-towing. By ... [...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".

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

1950s German Civil Utility Aircraft
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. Events By place Roman Empire * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger.

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
