DB-3
The Ilyushin DB-3, where "DB" stands for ''Dalniy Bombardirovshchik'' (Russian: Дальний бомбардировщик) meaning "long-range bomber", is a Soviet bomber aircraft of World War II. It was a twin-engined, low-wing monoplane that first flew in 1935. 1,528 were built. The DB-3 was the precursor of the Ilyushin Il-4 (originally designated DB-3F). Design and development The genesis of the DB-3 lay in the BB-2, Sergey Ilyushin's failed competitor to the Tupolev SB. Ilyushin was able to salvage the work and time invested in the BB-2's design by recasting it as a long-range bomber, again competing against a Tupolev design, the DB-2, to meet the stringent requirements of an aircraft capable of delivering a bombload to a range of at a maximum speed no less than . He had redesigned the BB-2 to take advantage of the radial Gnome-Rhône Mistral Major 14Kdrs engine, for which the Soviets had purchased a license in 1934 as the M-85, and had begun construction of the prototyp ...

Ilyushin Il-4
The Ilyushin Il-4 (DB-3F) (; NATO reporting name: Bob) is a Soviet twin-engined long-range bomber and torpedo bomber, widely used by the Soviet Air Force and Soviet Naval Aviation during World War II. Design and development In 1938, the Ilyushin design bureau redesigned the Ilyushin DB-3 to ease production and improve its performance, the revised version receiving the designation DB-3F (''Forsirovanniye'' or "boosted"). The aircraft's internal structure, particularly the wings, was extensively changed, eliminating the need for hand finishing of the structure, and with duralumin replacing the large scale use of steel in the earlier version.''Air International'' March 1986, p. 133.Gunston 1995, pp. 100–101. The aircraft's fuel system was redesigned, increasing its internal capacity while reducing the number of fuel tanks. The fuselage nose was lengthened to give more room for the navigator/bombardier while reducing drag. The prototype DB-3F, powered by the same Tumansky M-87B ...

Tupolev DB-2
The Tupolev ANT-37 (or DB-2) was a Soviet twin-engined long-range bomber designed and built by the Tupolev design bureau, the design team operating under the guidance of Pavel Sukhoi. The aircraft did not enter production, but three examples of the type were used for research and record breaking flights. Design and development Based on the unbuilt Tupolev ANT-36 (DB-1) single-engined bomber, the ANT-37 was a twin-engined monoplane of stressed skin, dural construction, fitted with a high-aspect-ratio wing and tailwheel landing gear, the main units retracting into the engine nacelles. Powered by Gnome-Rhône 14K radial engines, the prototype first flew on 16 June 1935. The program suffered a setback when the prototype crashed the following month, after the tail splintered into pieces during flight. A re-designed second prototype was built, designated as the DB-2D, in an attempt to overcome the design problems encountered during flight testing, particularly with the tail unit. ...

Gnome-Rhône Mistral Major
The Gnome-Rhône 14K ''Mistral Major'' was a 14-cylinder, two-row, air-cooled radial engine. It was Gnome-Rhône's major aircraft engine prior to World War II, and matured into a highly sought-after design that would see licensed production throughout Europe and Japan. Thousands of Mistral Major engines were produced, used on a wide variety of aircraft. Design and development In 1922 Gnome-Rhône purchased a license for the highly successful nine-cylinder single-row Bristol Jupiter radial engine and produced it until about 1930, alongside the smaller five-cylinder Bristol Titan. Starting in 1926, however, they used the basic design of the Titan to produce a family of new single-row radial engines, the so-called "K series". With increasing numbers of cylinders, these started with the 5K Titan, followed by the 7K Titan Major and 9K Mistral. By 1930, 6,000 of these engines had been delivered. However, the aircraft industry at that time was rapidly evolving and producing much la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Air Forces
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...

Sergey Ilyushin
Sergey Vladimirovich Ilyushin (; – 9 February 1977) was a Soviet aircraft designer who founded the Ilyushin aircraft design bureau. He designed the Ilyushin Il-2, Il-2 Shturmovik, which made its maiden flight in 1939. It is the most produced warplane, and remains the second most-produced aircraft in history, with some 36,000+ built, behind the US Cessna 172.

Tupolev SB
The Tupolev ANT-40, also known by its service name Tupolev SB ( – ''Skorostnoi Bombardirovschik'' – high speed bomber) and development co-name TsAGI-40, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934. The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation". Numerically the most important bomber in the world in the late 1930s, the SB was the first modern stressed skin aircraft produced in quantity in the Soviet Union and probably the most formidable bomber of the mid-1930s. It was produced in the Soviet Union and was also built under license in Czechoslovakia. Many versions saw extensive action in Spain, the Republic of China, Mongolia, Finland and at the beginning of World War II against Germany in 1941. It was also used in various duties in civil variants, as trainers and in many secondary roles. Successful in the Spanis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tumansky M-87
The Tumansky M-87 was a Soviet air-cooled aircraft radial engine that was developed in the late 1930s. It was a development of their licensed Gnome-Rhone 14K engines that started with the M-85. Development In 1934, USSR licensed the French Gnome-Rhone 14K aircraft engine producing 800 hp (595 kW), which entered production as the M-85. The engine was subsequently modified to M-86 which produced 960 hp (715 kW) at takeoff thanks to increased supercharging and a higher compression ratio. The M-87 was created to further increase the power output. Cylinders and pistons were revised to increase the compression ratio and the supercharger was redesigned. The resulting engine had better high-altitude performance and entered production in 1938. However, the engine proved unreliable and suffered from failure of gears in the reduction gearbox. Later the M-88 was designed to address the shortcomings of the M-87. At first the M-88 was not a success, but the designer ...

Medium Bomber
A medium bomber is a military bomber Fixed-wing aircraft, aircraft designed to operate with medium-sized Aerial bomb, bombloads over medium Range (aeronautics), range distances; the name serves to distinguish this type from larger heavy bombers and smaller light bombers. Mediums generally carried about two tons of bombs, compared to light bombers that carried one ton, and heavies that carried four or more. The term was used prior to and during World War II, based on available parameters of Aircraft engine, engine and Aerospace engineering, aeronautical technology for bomber aircraft designs at that time. After the war, medium bombers were replaced in world air forces by more advanced and capable aircraft. History In the early 1930s many air forces were looking to modernize their existing bomber aircraft fleets, which frequently consisted of older biplanes. The new designs were typically twin-engined monoplanes, often of all-metal construction, and optimized for high enough pe ...

Finnish Air Force
The Finnish Air Force (FAF or FiAF; ; ) is one of the branches of the Finnish Defence Forces. Its peacetime tasks are airspace surveillance, identification flights, and production of readiness formations for wartime conditions. The Finnish Air Force was founded on 6 March 1918. History The Finnish Air Force, one of the oldest air forces of the world, pre-dates the British RAF (founded as an independent entity on 1 April 1918) and the Swedish (founded on 1 July 1926). The first steps in the history of Finnish aviation involved Russian aircraft. The Russian military had a number of early designs stationed in the Grand Duchy of Finland, which until the Russian Revolution of 1917 formed an autonomous grand duchy under the Russian Empire. Soon after the Finnish declaration of independence of 6 December 1917, the Finnish Civil War of January to May 1918 broke out, in which the Soviets sided with the ''Reds'' – the socialist rebels with ties to Lenin's Bolshevik Party.

It is located on the Baikal-Amur Mainline, northeast of Khabarovsk. Population: History The future site of Komsomolsk-on-Amur was conquered by the Mongols in the 13th century, becoming part of the Yuan dynasty. It was later held by the Qing dynasty until the area was ceded to the Russian Empire in the treaty of Aigun in 1858. The village of Permskoye () was established on the later site of Komsomolsk in 1860 by migrant peasants from what was then called the Nizhne-Tambovsky District, Far Eastern Territory (now Khabarovsk Krai). The government of the Russian SFSR announced in 1931 plans to construct a shipyard on the Amur at the present site of Komsomolsk, with construction beginning in 1932. According to ...

Controllable Pitch Propeller
Controllability is an important property of a control system and plays a crucial role in many regulation problems, such as the stabilization of unstable systems using feedback, tracking problems, obtaining optimal control strategies, or, simply prescribing an input that has a desired effect on the state. Controllability and observability are dual notions. Controllability pertains to regulating the state by a choice of a suitable input, while observability pertains to being able to know the state by observing the output (assuming that the input is also being observed). Broadly speaking, the concept of controllability relates to the ability to steer a system around in its configuration space using only certain admissible manipulations. The exact definition varies depending on the framework or the type of models dealt with. The following are examples of variants of notions of controllability that have been introduced in the systems and control literature: * State controllability ...
