Yakovlev Yak-6
The Yakovlev Yak-6 was a Soviet twin-engined utility aircraft, developed and built during World War II. It was used as a short-range light night bomber and a light transport. Development In April 1942, the Yakovlev design bureau was instructed to design a twin-engined utility transport aircraft to supplement smaller single-engined aircraft such as the Polikarpov U-2. The design was required to be simple to build and operate.Gordon, Komissarov and Komissarov 2005, p. 235.Gunston 1995, p. 467. Design and construction work proceeded extremely quickly, with the first prototype Yak-6 flying in June 1942. It passed its state acceptance tests in September that year and was quickly cleared for production. The Yak-6 was a cantilever low-wing monoplane of all-wood construction with fabric covering. It had a retractable tailwheel undercarriage, with the main wheels retracting rearwards into the engine nacelles. The horizontal tail was braced. It was powered by two 140 hp Shvetsov M-1 ...

Shcherbakov Shche-2
The Shcherbakov Shche-2 (russian: Ще-2, produced 1943–1946), also known as the TS-1 and nicknamed "Pike", was a twin-engined utility aircraft manufactured in the Soviet Union, designed by Alexei Shcherbakov for construction by OKB-47, to meet an urgent requirement for a light transport and liaison aircraft for operation by the Soviet Air Force during the Second World War. Proving to be successful, it remained in service for a number of years post-war in both civilian and military roles in the Soviet Union, and with the air forces of several allied nations. 550 built, in use until 1956 (USSR) and 1960 (foreign users). Design and development The German invasion of the USSR revealed that there was an urgent requirement for a light transport and utility aircraft for use by the Soviet Air Force at the front. To meet this requirement, Aleksei Shcherbakov, who had previously worked at the Kalinin design bureau, and who had also heavily influenced the design of the Polikarpov I-153 ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

World War II Soviet Aircraft
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Aircraft
The JSC A.S. Yakovlev Design Bureau (russian: ОАО Опытно-конструкторское бюро им. А.С. Яковлева) is a Russian aircraft designer and manufacturer (design office prefix Yak). Its head office is in Aeroport District, Northern Administrative Okrug, Moscow. Overview The bureau formed in 1934 under designer Alexander Sergeyevich Yakovlev as OKB-115 (the design bureau has its own production base at the facility No.115), but dates its birth from 12 May 1927, the day of maiden flight of the AIR-1 aircraft developed within the Department of Light Aircraft of GUAP (Head Agency of Aviation Industry) under the supervision of A.S. Yakovlev. During World War II Yakovlev designed and produced a famed line of fighter aircraft. Irkut acquired Yakovlev in April 2004.

1940s Soviet Military Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 '' Ab urbe condita''). The denomination 194 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.

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Rocket Launcher
A rocket launcher is a weapon that launches an unguided, rocket-propelled projectile. History The earliest rocket launchers documented in imperial China consisted of arrows modified by the attachment of a rocket motor to the shaft a few inches behind the arrowhead. The rocket was propelled by the burning of the black powder in the motor; these should not be confused with early fire arrows, which were conventional arrows carrying small tubes of black powder as an incendiary that ignited only after the arrow hit its target. The rocket launchers were constructed of wood, basketry, and bamboo tubes. The launchers divided the rockets with frames meant to keep them separated, and the launchers were capable of firing multiple rockets at once. Textual evidence and illustrations of various early rocket launchers are found in the 1510 edition of the ''Wujing Zongyao'' translated by Needham and others at Princeton University. (The original ''Wujing Zongyao'' was compiled between 1040 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
