Bartini Beriev VVA-14
The Bartini Beriev VVA-14 ''Vertikaľno-Vzletayushchaya Amfibiya'' ( vertical take-off amphibious aircraft) was a wing-in-ground-effect aircraft developed in the Soviet Union during the early 1970s. Designed to be able to take off from the water and fly at high speed over long distances, it was to make true flights at high altitude, but also have the capability of flying efficiently just above the sea surface, using aerodynamic ground effect. The VVA-14 was designed by Hungarian-born designer Robert Bartini in answer to a perceived requirement to destroy United States Navy Polaris missile submarines. The final aircraft was retired in 1987. Development Bartini, in collaboration with the Beriev Design Bureau intended to develop the prototype VVA-14 in three phases. The VVA-14M1 was to be an aerodynamics and technology testbed, initially with rigid pontoons on the ends of the central wing section, and later with these replaced by inflatable pontoons. The VVA-14M2 was to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnetic Anomaly Detector
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field); military MAD equipment is a descendant of geomagnetic survey or aeromagnetic survey instruments used to search for minerals by detecting their disturbance of the normal earth-field. History Geoexploration by measuring and studying variations in the Earth's magnetic field has been conducted by scientists since 1843. The first uses of magnetometers were for the location of ore deposits. Thalen's "The Examination of Iron Ore Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use t ...

Ekranoplans
A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIG), ground-effect craft, wingship, flarecraft or ekranoplan (russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the moving wing and the surface below. Some models can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft. Design A ground-effect vehicle needs some forward velocity to produce lift dynamically, and the principal benefit of operating a wing in ground effect is to reduce its lift-dependent drag. The basic design principle is that the closer the wing operates to an external surface such as the ground, when it is said to be in ground effect, the less drag it feels. An airfoi ...

1970s Soviet Anti-submarine Aircraft
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. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon).

Beriev Be-2500
The Beriev Be-2500 Neptun (Russian: Бериев Бе-2500 Нептун) is a super heavy amphibious transport aircraft that, as of 2007, was in design and development by Russian design firm Beriev. The maximum takeoff weight is estimated at 2500 tons, hence its name. Design and development It has been designed to serve both as a conventional jet aircraft, flying at high altitudes transcontinentally, as well as a craft using the ground-effect at intercontinental routes across the sea. It is planned to fly via intercontinental routes, taking off from normal seaports without needing special infrastructure. The concept is thought to have some connection with the Lun-class ekranoplan of the 1970s. If it entered service, it would become the new largest airplane in the world. The concept of the aircraft was developed in the 1980s by the Beriev Design Office in collaboration with TsAGI and TsIAM. There are two versions of the design that differ in the arrangement of the gear units a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rybinsk RD-36-35PR
The Rybinsk RD-36-35 was a small lift turbojet engine, designed for use on V/STOL aircraft at the Rybinsk Engine Design Bureau (RKBM), designed by Pyotr A. Kolesov. Very little is known of this engine, probably due to confusion with the similarly designated Kolesov RD-36 and Lotarev D-36, which have little or no relation to the lift-jet.

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Soloviev D-30M
The Soloviev D-30 (now the Aviadvigatel PS-30) is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is probably the single most important turbofan engine developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed within an amazingly short period of time (about three years), the D-30 turned out to be one of the most reliable engines in the history of Soviet engine development, and it was recognized with the USSR State Prize. Design and development The original version of the Soloviev D-30 was developed specifically to power the Tupolev Tu-134 short-to-medium range jet airliner; however, it also served as a base for the development of a family of advanced engines. Engine development was started in the early 60s. Nevertheless, by 1966, the engine was put into serial production. The D-30 engine has a two-stage compression spoo ...

Beriev Be-1
The Beriev Be-1 was an experimental wing-in-ground-effect aircraft developed in the Soviet Union during the 1960s. Design and development In 1956, Robert Ludvigovich Bartini approached the Beriev design bureau with a proposal for a Wing-In-Ground-effect vehicle (WIG). The Be-1 became the first experimental prototype, used for exploring the stability and control of wing-in-ground-effect aircraft. The Be-1 featured two floats with very low aspect ratio wing sections between them and small normal wing panels extending outside the floats. Surface-piercing hydrofoils were mounted on the underside of the floats. The aircraft was powered by a single Tumansky RU-19 turbojet, mounted above the wing. The Be-1 was also equipped with landing gear. The aircraft was operated between 1961 and 1964. The first flight from water was made in 1964.
