Kinner K-5
The Kinner K-5 was a popular engine for light general and sport aircraft developed by Winfield B. 'Bert' Kinner. With the boom in civilian aviation after Charles Lindbergh's transatlantic flight the K-5 sold well. The K-5 was a rough running but reliable engine and the K-5 and its derivatives were produced in the thousands, powering many World War II trainer aircraft. The K-5 was followed by the B-5, R-5 and R-55.

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".

Davis D-1-K
The Davis D-1 is an American light two-seat parasol-winged monoplane of the late 1920s. Development and design The Davis D-1 was developed from the Davis V-3, which in turn was developed from the Vulcan American Moth. The Davis Aircraft Corporation had its factory at Richmond, Indiana. The D-1 is a parasol-winged aircraft of mixed construction with a two-spar wing and a rectangular welded steel-tube fuselage, the whole being covered by fabric. There are tandem open cockpits and it is fitted with a fixed tailwheel undercarriage which is attached by struts to the fuselage top and bottom. The wing is braced by struts from the lower fuselage. Various engines of between have been fitted. Operational history The D-1 was used from 1929 by sporting pilots and by private pilot owners for leisure flying. In September 1930, Art Chester bought a Davis D-1-85 parasol, and flew it to victory in the 1930 National Air Races. A late model D-1W "The Whistler II" was built in 1933 for Davis ...

73 Octane
Avgas (aviation gasoline, also known as aviation spirit in the UK) is an aviation fuel used in aircraft with spark-ignited internal combustion engines. ''Avgas'' is distinguished from conventional gasoline (petrol) used in motor vehicles, which is termed ''mogas'' (motor gasoline) in an aviation context. Unlike motor gasoline, which has been formulated since the 1970s to allow the use of platinum-content catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead (TEL), a toxic substance used to prevent engine knocking (premature detonation). There are ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline. Kerosene-based jet fuel is formulated to suit the requirements of turbine engines which have no octane requirement and operate over a much wider flight envelope than piston engines. Kerosene is also used by most diesel piston engines developed for aviation use, such as tho ...

Waco KSO
The Waco 10/GXE/Waco O series was a range of three-seat open-cockpit biplanes built by the Advance Aircraft Company, later the Waco Aircraft Company. Design and development The Waco 10 was a larger span development of the Waco 9, both single-engined three-seat single-bay biplanes constructed around steel-tube frames. The wing covering was fabric, and both upper and lower planes carried ailerons, which were strut linked. The two passengers sat side by side in a cockpit under the upper wing and ahead of the pilot, who had a separate cockpit. It had a split-axle fixed undercarriage and a tailwheel. The main undercarriage was fitted with hydraulic shock absorbers, unusual at the time on a light aircraft. The fin could be trimmed on the ground to offset engine torque, and the tailplane could be trimmed in flight. Initially it was powered by a Curtiss OX-5 water-cooled 90° V-8 engine producing . Its first flight was in 1927. It was numerically the most important type to be built ...

Sullivan Model K-3 Crested Harpy
The Sullivan Model K-3 Crested Harpy is a three place light sport aircraft of the 1920s. Design The Crested Harpy was a low wing monoplane, with an enclosed cabin which could accommodate a pilot and two passengers. It had conventional landing gear, and was powered by a Kinner K-5. The fuselage is constructed of welded steel tubing with aircraft fabric covering Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as ar .... The Wichita-assembled aircraft featured soundproofing materials.

Simplex C-2 Red Arrow
In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. For example, * a 0-dimensional simplex is a point, * a 1-dimensional simplex is a line segment, * a 2-dimensional simplex is a triangle, * a 3-dimensional simplex is a tetrahedron, and * a 4-dimensional simplex is a 5-cell. Specifically, a ''k''-simplex is a ''k''-dimensional polytope which is the convex hull of its ''k'' + 1 vertices. More formally, suppose the ''k'' + 1 points u_0, \dots, u_k \in \mathbb^ are affinely independent, which means u_1 - u_0,\dots, u_k-u_0 are linearly independent. Then, the simplex determined by them is the set of points : C = \left\ This representation in terms of weighted vertices is known as the barycentric coordinate system. A regular simplex is a simplex that is also a regular polytope. ...

Kreutzer Air Coach
The Kreutzer Air Coach is an American-built light trimotor transport aircraft of the late 1920s. Design and development Joseph Kreutzer formed the company of the same name in Los Angeles in late 1928. In 1929 the firm moved to Clover Field, Santa Monica, California, occupying the former Bach aircraft factory. Kreutzer was joined by Lawrence Brown and Albin Peterson who had designed the Brown-Mercury C-2.Data and information on the Air Coach series
, ''Aerofiles''. Retrieved 22 September 2010.
Kreutzer developed a series of small high-winged trimotor light transport aircraft, naming each the Air Coach. Each had a fixed tailwheel undercarriage with the two outboard engined slung from the supporting bracing struts to the high wing. The first model was the K-1 Air Coach of late 1928 which was powered by three Vel ...

Kinner Sportster
The Kinner Sportster was a 1930s American light monoplane built by Kinner Airplane & Motor Corporation. Design and development The Kinner Airplane & Motor Corporation had been producing radial engines since 1919 decided to enter the light aircraft market. The first design was a single-seat low-wing monoplane the Kinner Sportster K with a fixed tailwheel landing gear. Further versions followed with different engines. The strut-braced, low-wing, open cockpit, conventional gear aircraft featured folding wings. In 1933, an improved version the Sportwing B-2 was introduced. An enlarged four-seat version was produced in 1935 as the Kinner Envoy. Kinner became bankrupt in 1937 and rights to the Sportster were acquired by the Timm Aircraft Company. The Sportster was also produced after the Bankruptcy by Security-National Corp as the Security S-1 Airster Variants ;K Sportster :Powered by a Kinner K-5 engine. ;K-5 Sportster : ;B Sportster :Powered by a Kinner B-5 engine. ;B-1 Sport ...

Chamberlin C-2
The Chamberlin is an electro-mechanical keyboard instrument that was a precursor to the Mellotron. It was developed and patented by the American inventor Harry Chamberlin from 1949 to 1956, when the first model was introduced. There are several models and versions of the Chamberlin. While most are keyboard-based, there were also early drum machines produced and sold. Some of these drum patterns feature the work of Chamberlin's son Richard. Development Harry Chamberlin's idea for the instrument came from recording himself playing an organ, and conceiving its playback as entertainment. He designed the first Chamberlin instrument as early as 1949, intended as a home entertainment device for family sing-alongs, playing the big band standards of the day. The Chamberlin's use as a commercial instrument in rock (or rock and roll) music was not considered, as Harry Chamberlin disliked rock music and rock musicians. The Chamberlin has a piano-style keyboard. Underneath each key is a ...
