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] |
