Lieutenant Mikhail Ivanovich Safonov (13 November 1893 – May 1924) was a World War I flying ace credited with five aerial victories. He began his naval service on 20 September 1909, when he entered Saint Peterburg's Imperial Russian Naval Academy. When he applied for aviation training in September 1915, he was a professional sailor with six years naval training and seagoing service. On 1 December 1915, he soloed. On 2 April 1916, he was classified as a naval pilot. He was posted to pilot Grigorovich M-9 flying boats that mounted a Madsen machine gun.

Madsen Machine Gun
The Madsen is a light machine gun that Julius A. Rasmussen and Theodor Schouboe designed and proposed for adoption by Colonel Vilhelm Herman Oluf Madsen, the Danish Minister of War, and that the Royal Danish Army adopted in 1902. It was the world's first true light machine gun produced in quantity and Madsen was able to sell it in 12 calibres to over 34 countries. The gun saw extensive combat usage for over 100 years, with continued use in limited quantities worldwide into the 2010s. The Madsen was produced by Compagnie Madsen A/S (later operating as Dansk Rekyl Riffel Syndikat A/S and then Dansk Industri Syndikat A/S). Design details The design dates to 1880s, with the Danish Self Loading rifle M.1888 (; ), being a precursor design. In 1883 Captain Vilhelm Herman Oluf Madsen (a Danish artillery officer), and Rustmester Rasmussen (a weapons technician at the Danish Arsenal), began working on a recoil-operated self-loading rifle; Madsen developed the idea and Rasmussen fabr ...

Grigorovich M-15
Grigorovich M-15 (alternative designation ShCh M-15 (russian: Щ М-15), sometimes also Shchetinin M-15) was a successful Russian World War I-era biplane flying boat, developed from the M-9 by Grigorovich. Development The M-15 was a smaller version of the M-9 intended to replace the latter, however it was only built in small numbers due to shortage of the more powerful Hispano-Suiza engines. After the summer of 1917 it was mostly used as a trainer. Two M-15s fell into Finnish hands during the Russian Civil War, having been left at Åland and Turku. The Russian officer J.Herbert flew the Åland aircraft to mainland Finland and was awarded an officer's title in the Finnish Air Force. Only the Åland aircraft was in flyworthy condition. The aircraft was flown until 1919. Variants ;M-15:Reconnaissance / skiplane powered by Hispano-Suiza 8A engines. ;M-17: the second prototype powered by a Clerget 9B engine. ;M-18: powered by a Hispano-Suiza 8B engine.

Float Plane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farman MF
Farman Aviation Works (french: Avions Farman) was a French aircraft company founded and run by the brothers Richard, Henri, and Maurice Farman. They designed and constructed aircraft and engines from 1908 until 1936; during the French nationalization and rationalization of its aeronautical industry, Farman's assets were assigned to the ''Société Nationale de Constructions Aéronautiques du Centre'' (SNCAC). In 1941 the Farman brothers reestablished the firm as the "''Société Anonyme des Usines Farman''" (SAUF), but only three years later it was absorbed by Sud-Ouest. Maurice's son, Marcel Farman, reestablished the SAUF in 1952, but his effort proved unsuccessful and the firm was dissolved in 1956. The Farman brothers designed and built more than 200 types of aircraft between 1908 and 1941. They also built cars until 1931 and boats until 1930. Background In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve the design of the air ...

Tallinn
Tallinn () is the most populous and capital city of Estonia. Situated on a bay in north Estonia, on the shore of the Gulf of Finland of the Baltic Sea, Tallinn has a population of 437,811 (as of 2022) and administratively lies in the Harju '' maakond'' (county). Tallinn is the main financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city Tartu, however only south of Helsinki, Finland, also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name Reval. Tallinn received Lübeck city rights in 1248,, however the earliest evidence of human population in the area dates back nearly 5,000 years. The medieval indigenous population of what is now Tallinn and northern Estonia was one of the last " pagan" civilisations in Europe to adopt Christianity ...

Baku
Baku (, ; az, Bakı ) is the capital and largest city of Azerbaijan, as well as the largest city on the Caspian Sea and of the Caucasus region. Baku is located below sea level, which makes it the lowest lying national capital in the world and also the largest city in the world located below sea level. Baku lies on the southern shore of the Absheron Peninsula, alongside the Bay of Baku. Baku's urban population was estimated at two million people as of 2009. Baku is the primate city of Azerbaijan—it is the sole metropolis in the country, and about 25% of all inhabitants of the country live in Baku's metropolitan area. Baku is divided into twelve administrative raions and 48 townships. Among these are the townships on the islands of the Baku Archipelago, and the town of Oil Rocks built on stilts in the Caspian Sea, away from Baku. The Inner City of Baku, along with the Shirvanshah's Palace and Maiden Tower, were inscribed as a UNESCO World Heritage Site in 2000. The c ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis fo ...

Warrant Officer
Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States. The name of the rank originated in medieval England. It was first used during the 13th century, in the Royal Navy, where Warrant Officers achieved the designation by virtue of their accrued experience or seniority, and technically held the rank by a warrant—rather than by a formal commission (as in the case of a commissioned officer). Nevertheless, WOs in the British services have traditionally been considered and treated as distinct from non-commissioned officers, as such (even though neither group has, technically, held a commiss ...

Russian Orthodox
Russian Orthodoxy (russian: Русское православие) is the body of several churches within the larger communion of Eastern Orthodox Christianity, whose liturgy is or was traditionally conducted in Church Slavonic language. Most Churches of the Russian Orthodox tradition are part of the Eastern Orthodox Church. Origin Historically, the term "Greek Orthodox" has been used to describe all Eastern Orthodox churches, since the term "Greek" can refer to the heritage of the Byzantine Empire. However, after the fall of Constantinople, the Greek influence decreased. Having lost its Christian '' basileus'' after the Turkish conquest, Constantinople, as a center of power, lost a significant part of its authority. On the other hand, the Moscow rulers soon began to consider themselves real '' Tsars'' (this title was already used by Ivan III), and therefore, according to them, the center of the Eastern Orthodox Church should be located in Moscow, and thus the bishop of Mo ...
