Boris Stechkin
Boris Sergeyevich Stechkin (24 July 1891 – 2 April 1969) was a Russian and Soviet scientist, engineer and inventor. He developed a theory of heat engines and was involved in construction of many Soviet aircraft engines. He was also co-developer of Sikorsky Ilya Muromets (the first four-engine airplane and bomber, 1913) and Lebedenko's Tsar Tank (the largest armored vehicle in history, 1916–1917). He died in Moscow on 2 April 1969.

Heat Engines
A heat engine is a system that transfers thermal energy to do mechanical or electrical work. While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds of energy, particularly electrical, since at least the late 19th century. The heat engine does this by bringing a working substance from a higher state temperature to a lower state temperature. A heat source generates thermal energy that brings the working substance to the higher temperature state. The working substance generates work in the working body of the engine while transferring heat to the colder sink until it reaches a lower temperature state. During this process some of the thermal energy is converted into work by exploiting the properties of the working substance. The working substance can be any system with a non-zero heat capacity, but it usually is a gas or liquid. During this process, some heat is normally lost to the surroundings and is ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine. The aircraft never flew, but a patent was filed for routing exhaust gases into the duct to augment thrust. * 1914: Auguste Rateau suggests using exhaust-powered compressor – a turbocharger – to improve high-altitude performance; not accepted after the ...

Sikorsky Ilya Muromets
The Sikorsky ''Ilya Muromets'' (; versions S-22, S-23, S-24, S-25, S-26 and S-27) was a class of Russian pre-World War I large four-engine commercial airliners and military heavy bombers used during World War I by the Russian Empire. The aircraft series was named after Ilya Muromets, a hero in Russian folklore. The series was based on the Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky. The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board. The Ilya Muromets was the world's first multi-engine aircraft in production and at least sixty were built.Sikorsky 1938, p. 96. During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit.Massenkov et al. 1994, p. 23. This heavy bomber was unrivaled in the early stages of the war, as the Central Powers had no air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikolai Lebedenko
Nikolay Lebedenko () was a Russian military engineer, mostly known as the main developer of the Lebedenko Tank, or the Tsar Tank, which was the largest armored vehicle in history, constructed in 1916–1917. Lebedenko was employed in a private firm, that worked for the Russian War Department, designing artillery devices before and during World War I, as well as the bomb release mechanism for the Ilya Muromets bomber. There is little known about the biography of Lebedenko or his year of birth and death. A page on the web resource of the Moscow City Museum states he was reportedly born on 2 March 1879 and died on 26 May 1948. During the war, he owned a private laboratory on Sadovaya-Kudrinskaya Street in Moscow, where he developed his projects for the Imperial Russian Army, including the Tsar Tank. His idea intrigued Nikolai Zhukovsky, a scientist he had met earlier in a scientific and medical conference before the war, and thus, development began. After he left Russia for the Un ...

Armored Vehicle
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid compos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burials At Novodevichy Cemetery
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Evidence suggests that some archaic and early modern humans buried their dead. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life. Methods of burial may be heavily ritualized and can include natural burial (sometimes called "green burial"); embalming or mummification; and the use of containers for the dead, such as shrouds, coffins, grave liners, and buri ...
