Viktor Fedorovich Bolkhovitinov
Viktor Fyodorovich Bolkhovitinov (Виктор Фёдорович Болховитинов) (4 February 1899 – 29 January 1970) was a Soviet engineer and team-leader of the developers of the Bereznyak-Isayev BI-1 aircraft. He was also the lead designer of the Bolkhovitinov DB-A bomber named after him. Bolkhovitinov was one of the first graduates of the Zhukovsky Academy. In 1934, he designed a modernized version of the Tupolev TB-3 bomber called the DB-A (long-range bomber of the academy). On August 12 of 1937, a DB-A attempted to fly over the North Pole to the USA, but the crew perished. In 1937, he designed the "S" or "Spartak", a small sleek high-speed bomber with a long greenhouse canopy. Two contra-rotating props were driven by a pair of Klimov M-103 V-12 engines. Development of the aircraft and its planned variants was discontinued when the war began. In 1940, Bolkhovitinov became head of his own experimental design bureau OKB-293. Based on a plane design by Ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...

Military Personnel From Saratov
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970 Deaths
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 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.

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Doctorate
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals d ...

Factory
A factory, manufacturing plant or a production plant is an industrial facility, often a complex consisting of several buildings filled with machinery, where workers manufacture items or operate machines which process each item into another. They are a critical part of modern economic production, with the majority of the world's goods being created or processed within factories. Factories arose with the introduction of machinery during the Industrial Revolution, when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops". Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, some having rail, highway and water loading ...

Matus Bisnovat
Matus Ruvimovich Bisnovat (russian: Матус Рувимович Бисноват, 23 October 1905, Nikopol – 8 November 1977) was a Soviet aircraft and missile designer. Bisnovat attended the Moscow Aviation Institute (MAI), graduating in 1931. In 1938, he headed a research team in Central Aero-Hydrodynamics Institute TsAGI, Zhukovsky, where several high-speed experimental airplanes were developed, the SK-1, SK-2 and SK-3. From 1942 - 1944 Bisnovat oversaw the development of the "302" rocket/ramjet fighter in NII-3, supervised by Andrey Kostikov. In 1946 he became head of Plant no. 293 and a team of engineers formerly in the OKB-293 of Viktor Bolkhovitinov. There Bisnovat managed some later work on the Bereznyak- Isaev BI-1 Rocket-powered aircraft. In 1948, with engine designer Aleksei Isaev he worked on the supersonic aircraft " Bisnovat 5". In 1952 he developed the infrared homing air-to-air missile SNARS-250. Bisnovat fell prey to a 1953 anti-Semitic campaign ag ...

Research Institute
A research institute, research centre, research center or research organization, is an establishment founded for doing research. Research institutes may specialize in basic research or may be oriented to applied research. Although the term often implies natural science research, there are also many research institutes in the social science as well, especially for sociological and historical research purposes. Famous research institutes In the early medieval period, several astronomical observatories were built in the Islamic world. The first of these was the 9th-century Baghdad observatory built during the time of the Abbasid caliph al-Ma'mun, though the most famous were the 13th-century Maragheh observatory, and the 15th-century Ulugh Beg Observatory. The Kerala School of Astronomy and Mathematics was a school of mathematics and astronomy founded by Madhava of Sangamagrama in Kerala, India. The school flourished between the 14th and 16th centuries and the original discoverie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
