Kocjan Bąk
The Bąk (Horse-Fly) was a single seat motor glider designed and built in Poland from 1936. Development Affiliated to D.W.L., the ''Warsztaty Szybowcowe'' – glider workshops produced the Bᾳk, designed by Antoni Kocjan, to compete with the ITS-8 which had been designed to a specification from the I.T.S.M. (''Instytut Techniki Szybownictwa i Motoszybownictwa'' – institute of gliding and motor-gliding techniques), for a cheap ultra-light aircraft suitable for converting trained glider pilots to powered flying. The Bąk I was an immediate success with excellent performance and good handling qualities, passing I.T.L. (''Instytut Techniczny Lotnictwa'' – Technical aviation institute) and airworthiness tests without problems, also proving to have relatively good gliding performance. The Bąk was built primarily of wood with plywood in a semi-monocoque fuselage and cantilevered single spar wooden wings, with plywood skinned leading edge torsion boxes and wing roots, mid set o ...

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".

Saroléa Albatros
The Saroléa Albatros was a 22 kW (30 hp) flat twin air-cooled aircraft engine, produced just before World War II in Belgium. Design and development In the 1930s, Saroléa were one of the biggest motorcycle producers in Europe, using their own engines. They also designed and built small flat twin engines for light aircraft. The Albatros dates from about 1938. It had chrome-nickel steel machined piston barrels, with closely spaced cooling fins. The cylinder heads were aluminium alloy, with hemispherical combustion chambers and bronze valve seats. The connecting rods had big and little ends with roller bearings. The crankshaft was a chrome nickel steel forging, running in a combination of roller and ball bearings; a ball bearing at the output side crankshaft end allowed the Albatros to be used in either pusher or tractor configuration. With a maximum power of only at 2,650 rpm, the Abatros was targeted at the small single seat sports aircraft of the day. Appl ...

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 ...

Mid-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

1930s Polish Civil Trainer Aircraft
Year 193 (Roman numerals, CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

RWD (aircraft Manufacturer)
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym. History They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (''Sekcja Lotnicza Koła Mechaników Studentów''), where they manufactured their first designs. From 1926 they designed several aircraft alone ( Drzewiecki JD-2 and WR-1), in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Okęcie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organization. ...

Scheibe SF-24 Motorspatz
The Scheibe SF-24 Motorspatz ( en, Motor Sparrow) is a West German high-wing, single-seat motor glider that was designed by Egon Scheibe and produced by Scheibe Flugzeugbau.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 126. Soaring Society of America, November 1983. USPS 499-920 Derived from the unpowered Scheibe Spatz, the Motor Spatz was described in 1983 by Soaring Magazine as "one of the more primitive of the breed of self-launching sailplanes". Design and development The Motorspatz was an early attempt to create a self-launching glider. Scheibe accomplished this by mounting a Hirth engine in the nose of a mostly stock Spatz glider. The SF-24 is constructed with a welded steel tube fuselage that mounts the monowheel landing gear, with a small tail wheel for ground maneuvering. The wings and tail surfaces are built with wooden structures and covered in doped aircraft fabric covering. The wing has a span, employs an Mu 14% airfoil and mounts spoilers for ...
