If only valve c is open, since at this point the variation of pressure is always zero, no energy can be taken consfantinescu by the motor n, and the stationary wave will persist. Share on Twitter Tweet.

The laws discovered by Constantinescu, used in sonicity are constanrinescu same with the laws used in electricity. The Constantinesco synchronization gear or “CC” gear was first used operationally on the D.

For pipes with greater diameter greater velocity can be achieve for same value of k.

George Constantinescu – Wikipedia

Although Constantinescu was recognized among bigger names such as Edison, Graham Bell and Marie Curie by the Graphic magazine inhis name was not mentioned over the years as much as other inventors.

The effective hydromotive force will be: George Constantinescu Mathematical physics Romanian inventions. The system was not adopted on British railways but it was applied to some consyantinescu on the Romanian State Railways. If Nicolae Tesla invented and transmitted electromagnetic waves electromagnetic oscillations through the atmosphere, George Constantinescu invented mechanical sonic oscillations with which he transmitted sonic waves only through continuous media tubes or pipes, water, constantinescj, various liquids, air, gas, or full bars.

Gogu Constantinescu was one of those brilliant minds, whose ideas vonstantinescu long outstripped his physical existence, but which today preserves its topicality, surprising by its accuracy, inventiveness and applicability.

We all know at least a few famous inventors, however, some like Gogu Constantinescu have never become famous for unknown reasons.

Constantinescu has continued his successful career, building bridges over Siret in Adjud, Roman and Racatau. This page was last edited on 12 Juneat Inhe published the book A treatise on transmission of power by vibrations [4] in which he described his Theory of sonics. Most of his discoveries never could be public because were kept top secret by British ministery of defense ,and were about military technology,about plains and strategic weapons.

If we have a large volume vessel d, compared with the stroke volume of piston b, the capacity d will act as a spring taking out the energy of direct or reflected waves at high pressure, and giving back energy when pressure falls.

Later on, in his life, he has projected several well-known buildings throughout the country including the Sports Stadium ,the Chamber Commerce building, and the Constanta mosque.

Share on Digg Share. His inventions patents were obtained in countries like: He was responsible for creating a new field of constantinescuu, called “sonicity,” which describes the transmission of energy through vibrations in fluid or solid bodies.

The birth of the theory of sonics [1] can be considered the publication of the book A treatise on transmission of power by vibrations in by the Romanian scientist Gogu Constantinescu. In other projects Wikimedia Commons. One of his teachers was Anghel Saligny,another great inventor of the world,about him we will write also in the following article, next time. His father born in ,influenced him, being a professor of mathematics and engineering science, specialized in mathematics at the Sorbonne University.

We can say that what Tesla did in electronics, Constantinescu succeeded in mechanics. The most important findings are; — the asphalt, modern road rail vehicles — the theory of sonicity; power transmission through liquids, solids and gases, — device for firing synchronized bombers of World War I, — the use of reinforced concrete sleepers straight bridge, — railway motor wagon, — the first automatic transmission cars and locomotives without clutch and Gear — first glider in the world — first sonic radiator — several patents for improvements the diesel engines carburettors — mechanical torque converter actuated by a pendulum,Constantinescu cannon sonic converter.


It was also tried on rail vehicles.

Constantinescu argued that, contrary to popular belief, liquids are compressible. Gogu Constantinescu, however, has managed to build an arched bridge using this material, although the Romanian government in that time did not believe in its utility. Wikimedia Commons has media related to George Constantinescu. If the crank continues rotation at uniform speed, a zone of maximum pressure will start from the piston at the same time the reflected gou came to the piston, as a result the maximum pressure will double.

He was the first to use reinforced concrete in the construction of buildings in Romania among the buildings he built, we can costantinescu During his years as a student, he has promoted the usage of steel reinforced concrete to his students.

Oxen House, ConistonUnited Kingdom. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. Did you know that? In alternating current flowing a pipe the friction appear at the surface of the pipe and also in liquid itself.

He is the creator of the theory of sonicsa new branch of continuum mechanicsin which he described the transmission of mechanical energy through vibrations.
