Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

LWD Zuch
The Zuch was a Polish aerobatics and trainer aircraft, built in 1948 in the LWD bureau and produced in a small series. Design and development The aircraft was a development of a military and civilian trainer plane LWD Junak-1, meant as a civilian aerobatics and trainer plane for the Polish Aero Club. It was designed in the ''Lotnicze Warsztaty Doświadczalne'' (LWD - Aircraft Experimental Workshops), a main designer was Tadeusz Sołtyk. The design was similar to Junak-1, the main difference was en engine. Unlike Junak, its fixed landing gear, in massive covers, was lacking struts. It was also fitted with split flaps and had slightly enlarged rudder (similar improvements were later adapted in Junak-2). Description Mixed construction (steel and wood) low-wing monoplane, conventional in layout. Fuselage of a steel frame, covered with canvas, in front with metal sheet. Two-spar wings of wooden construction and trapezoid shape, canvas and plywood covered, fitted with split flaps. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Air-cooled Radial Piston Engines
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Continental R-670
The Continental R-670 (factory designation W670) was a seven-cylinder four-cycle radial aircraft engine produced by Continental displacing 668 cubic inches (11 litres) and a dry weight of . Horsepower varied from 210 to 240 at 2,200 rpm. The engine was the successor to Continental's first radial engine, the 170 hp Continental A-70. This engine was used on many aircraft in the 1930s and 1940s. The R-670 was widely used in the PT-17 Stearman primary training aircraft of the U.S. military.Gunston 1989, p.42. In addition to being used in aircraft, the R-670 was used in a number of light armored vehicles of World War II.

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".

VL Viima
VL Viima, constructed by the State Aircraft Factory ( fi, Valtion lentokonetehdas or ''VL'') is a Finnish two-seat, biplane trainer used by the Finnish Air Force from the late 1930s to the early 1960s. After military service, several were released into civil use. Design The Viima II is a single engined, tandem seater biplane. ''Viima'' means ''Gale'' in English. Post war, VL was eventually absorbed into Valmet, so the aircraft is often referred to as the Valmet Viima. It has unequal span, staggered single bay wings built around two box spars with plywood ribs. The interplane struts are N-shaped. The wings are fabric covered and carry four ailerons in all; the upper and lower ailerons are externally linked. The fuselage and tail unit are constructed of chrome-molybdenum steel and are fabric covered. The tailplane, mounted on top of the fuselage, is wire braced to the small triangular fin. Both the fin and the tailplane are adjustable when on ground. The deep, wide chord rudder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIM-II
The SIM-II ( sr, СИМ-II) was a 1930s Yugoslav Sports and tourist plane and the plane for the basic training, one-engined, with two crew members. It was designed by Sima Milutinović and built at the "S.Vlajković i sinovi" factory in Belgrade. Design and development Aircraft SIM-II was the first independent project of the most prolific designer of the Yugoslav aircraft, engineerSima Milutinović. Project of the school aircraft started Sima Milutinović during his specialization in the French aviation factories in late 1920s, where it attracted a solution that saw the flight school Blerio to the student and teacher sit on the plane next to each other. Upon his return to Yugoslavia, is hard at work, and aircraft that made the project was named SIM-II. Design was started at the end of the 1929 and the beginning of 1930. The prototype was developed in the aircraft factory in Belgrade "S. Vlajković and Sons", directed by the private constructor and with the financial help of hi ...

RWD-17W
The RWD 17 was a Polish aerobatics-trainer aircraft of 1937, parasol wing monoplane, constructed by the RWD team. Development The aircraft was designed for an order of the LOPP paramilitary organization, as an interim trainer aircraft between primary trainer RWD 8 and single-seater aircraft, demanding higher skills, like the RWD 10. It was also fitted to aerobatics. The construction of the new aircraft was very similar to the RWD 8, but almost all parts were newly designed. Main visual difference were twin struts supporting wings, instead of V-struts, and two-part wing instead of three-part, without central section. The works started in 1936, and the main designer was Bronisław Żurakowski of the RWD bureau. The first prototype (registration SP-BMX) was flown in August 1937 in Warsaw. After state trials in 1937, it was accepted for production, and in 1938 a short series of RWD 17 was produced (23 serial RWD 17 were in the Polish registry). In early 1938, a floatplane varian ...
