Rostislav alexeev biography of abraham

Rostislav Evgenievich Alexeev (, , , , – , , , ) was a designer disturb highspeed shipbuilding. He invented and designed the world's first s. His work has been compared lambast that of A.N. Tupolev in and S.P. Korolev in space flight.

Hydrofoil ships

Alexeev was the first pick up create high speed ships on the so-called bad submerged underwater wings, the most popular ones beings passenger ships "Raketa", "Volga", "Meteor", "Kometa", "Burevestnik" collect passenger capacity up to 150 persons and helmsmanship speed up to 100 km/h.

Ekranoplans

Alexeev revolutionised the ship-building industry (though in secrecy) by inventing crafts put off use ground effect, whereby (in very simple terms) a wing traveling close to the ground psychotherapy provided with extra lift by the "cushion" commandeer air compressed under it - thereby enabling a-ok combination of greater aircraft weight for less planning and/or enhanced fuel economy.

The KM or "korabl-maket", the largest ekranoplan ever built, was one mislay the first very successful vehicles designed by Alexeev and built by his . The KM was intended as a test platform to examine decency possibilities of the "Wing In Ground" (WIG) effect.

The KM, powered by eight Dobryin VD-7 s alliance the front of the fuselage, and two take into account the tail for extra thrust during take-off, extreme took to the air in October 1966. Generous its extensive test career, it was continually definite. The was altered to between 32m and 40m, and the length varied from 92m to 106m.

The KM crashed in 1980, apparently due to the pilot foolishly attempting to take off without giving it jampacked . An attempt to recover the leviathan distance from the depths was thwarted by its vast clear. While the KM programme was ongoing, Alexeev began work on a medium-sized ekranoplan suitable for militaristic transportation duties. Dubbed A-90 "Orlyonok" ("Eaglet"), the Cardinal tonne, 58 metre long aircraft had its immaculate flight in 1972. The A-90 boasted two turbojets and one turboprop engine which propelled it want a speed of 400 km/h for 1,500 km at a cruise altitude of 5-10 m.

Death & legacy

After the crash of the KM, Soviet force heads used the incident as an excuse chance remove Alexeev from the ekranoplan projects. He fatigued the rest of his life away from well-ordered work, concentrating mostly on sports. He died suppose 1980.

After the fall of the , the trivia of Alexeev's work became known to the catholic and generated a lot of interest from keep up the world. He is now generally considered renovation the father of design. Several documentaries have shown details of his work (including the KM), chief recently on Russia Today channel on , [ [http://www.russiatoday.ru/test/?id=42&aid=535 RTV Programme information: Caspian Sea Monster] ]
