Bratukhin G-3
The Bratukhin Omega (also known as the 2MG) was an early Soviet helicopter, the first product of a new Soviet design bureau, OKB-3 that was created from within TsAGI specifically to develop rotary-wing aircraft. Bratukhin's design was a side-by-side twin rotor machine, with each rotor carried on a long outrigger truss. The Omega's rotors were each powered by a separate engine carried in a nacelle also at the end of the truss. Captive trials commenced in August 1941 and revealed severe problems with engine vibration and overheating. Before these could be addressed, however, OKB-3 was evacuated ahead of the German advance into the Soviet Union. Design and development Flight testing recommenced in mid-1942, with the Omega still flying on a tether until early the next year. Free-flight trials confirmed the design as basically sound, so although the engine difficulties were never fully resolved, Bratukhin was convinced that further development along the same general lines would prove ...

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".

Focke Achgelis Fa 223
The Focke-Achgelis Fa 223 ''Drache'' () was a helicopter developed by Germany during World War II. A single Bramo 323 radial engine powered two three-bladed rotors mounted on twin booms on either side of the cylindrical fuselage. Although the Fa 223 is noted for being the first helicopter to attain production status, production of the helicopter was hampered by Allied bombing of the factory, and only 20 were built. The Fa 223 could cruise at with a top speed of , and climb to an altitude of . The ''Drache'' could transport cargo loads of over at cruising speeds of and altitudes approaching . Design and development Henrich Focke had been removed by the Nazi regime from the company he had co-founded in 1936. Though the ostensible reason was that he was "politically unreliable", the RLM decision to phase Focke-Wulf into the production program of the almost-ready Messerschmitt Bf 109 necessitated an influx of capital to fund the immediate expansion of the company's produ ...

Military Helicopters
A military helicopter is a helicopter that is either specifically built or converted for use by military forces. A military helicopter's mission is a function of its design or conversion. The most common use of military helicopters is transport of troops, but transport helicopters can be modified or converted to perform other missions such as combat search and rescue (CSAR), medical evacuation (MEDEVAC), airborne command post, or even armed with weapons for attacking ground targets. Specialized military helicopters are intended to conduct specific missions. Examples of specialized military helicopters are attack helicopters, observation helicopters and anti-submarine warfare helicopters. Types and roles Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipment. To ...

Platt-LePage XR-1
The Platt-LePage XR-1, also known by the company designation PL-3,Francillon 1990, p.49. was an early American transverse rotors helicopter, built by the Platt-LePage Aircraft Company of Eddystone, Pennsylvania. The winner of a United States Army Air Corps design competition held in early 1940, the XR-1 was the first helicopter tested by the USAAF, flying in 1941. The flight testing of the XR-1 proved troublesome, and although continued testing showed that the design had promise, other, improved helicopters were becoming available before the XR-1 was ready for service. As a result, the development of the aircraft was terminated in 1945. Design and development Developed during 1939 from an earlier, unsuccessful design, the PL-1,Charnov 2003, p.171. the Platt-LePage Model PL-3 was the winner of a 1940 design competition, held under the terms of the Dorsey-Logan Act, for the supply of a helicopter design to the United States Army Air Corps.

MV-6
The Renault 6P, also called the Renault Bengali, was a series of air-cooled 6-cylinder inverted in-line aero engines designed and built in France from the late 1920s, which produced from to . Design and development Charles Lindbergh's Atlantic Ocean crossing in 1927 inspired Renault to enter the light aero-engine market to diversify the range of engines they offered. To complement the 4P four-cylinder engines, Renault developed the 6P series, with bore and stroke; by adding two cylinders of the same bore and stroke. Developed by Charles-Edmond Serre, the 6P evolved to give , using bore steel cylinder liners, aluminium alloy cylinder heads attached by long studs to the crankcase, Duralumin connecting rods and magnesium alloy crankcase. The 6P was also produced in the USSR, as the MV-6, (MV - ''Motor Vozdushniy'' / ''Motor Voronezhskiy'' - air-cooled engine / Voronezh built engine ).
