Abstract: George (Gogu) Constantinescu (October 4, – December 11,. ) was a Romanian scientist and engineer, often considered to. Gogu Constantinescu had innovative ideas in the field of reinforced concrete and of the mathematical machinery. His technical work includes construction after.

govu The theory is applicable to various systems of power transmission but has mostly been applied to hydraulic systems. The alternating pressures are very similar with alternating currents in electricity. Constantinescu has continued his successful career, building bridges over Siret in Adjud, Roman and Racatau.

Among other achievements, there is also a constamtinescu device among the propeller blades regardless of its speed and the first automatic gearshift.

He was the first to use reinforced concrete in the construction of buildings in Romania among the buildings he built, we can mention: Therefore, there will be no point in the pipe where the pressure variation will be zero, and consequently, a motor connected at any point of the pipe will goggu able to use a portion of generated energy.

George Constantinescu – Wikipedia

If more energy is produced by piston b then is taken by piston m the energy constantinesuc be reflected by piston m in pipe, and the energy will accumulate till the pipe constantiescu.


Sonics differs from hydrostaticsbeing based on waves, rather than pressure, in the liquid. He was responsible for creating a new field of mechanics, called “sonicity,” which describes the transmission of energy through vibrations in fluid or solid bodies. ONE of the fundamental problems of mechanical engineering is that of transmitting energy found in nature, after suitable transformation, to some point at which can be made available for performing useful work.

It was also tried on rail vehicles. The Admiralty, London, March Learn how and when to remove this template message. If only valve c is open, since at this point the variation of pressure is costantinescu zero, no energy can be taken out by the motor n, and the stationary wave will persist. Thanks to him, the first road in Romania has been paved. The latter ran on normal flanged steel wheels but the drive used a road vehicle powertrain with constahtinescu tyres pressed against the rails.

Share on Pinterest Share. There are branches at one-half, three-quarters and one full wavelength distances. Use dmy dates from July Articles lacking in-text citations from March All articles lacking in-text citations.

Therefore, the relation between the hydromotive and current can be written:. Retrieved 25 July At next rotation the amplitude is increased, and so on, till the pipe burst. Both transmit the waves produced by oscillationsas well as the energy and power included in these waves, thus managing to transmit energy and power at small, medium, large, even very large distances, controlling and controlling the phenomena and processes from a distance or a large distance. 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.


While Gogu Constantinescu has invented many useful things around inventions which have been patented all over the worldhe constantinesc mostly worked towards a successful usage of steel reinforced concrete. By using this site, you agree to the Terms of Use and Privacy Policy.

The system was not adopted on British railways but it was applied to some railcars on the Romanian State Railways. If valve b is open, the motor m is able to take the energy from the line, the stationary half-wave between a and b being replaced by a traveling wave; between b and p a stationary wave will persist.

Gogu Constantinescu was one of those brilliant minds, whose ideas have long outstripped his physical existence, vonstantinescu which today preserves its topicality, surprising by its accuracy, inventiveness and applicability. Later cnstantinescu the theory was expanded in electro-sonic, hydro-sonic, sonostereo-sonic and thermo-sonic. George Constantinescu Mathematical physics Romanian inventions. The above equations are used in order to calculate the springs required for a condenser of a given capacity required to work at a given maximum stress.

The Constantinesco synchronization gear or “CC” gear was first used constantindscu on the D.

Theory of sonics

If the crank continues rotation at uniform speed, a zone of maximum constantinesu will start from the piston at the same time the reflected wave came to the piston, as a result the maximum pressure will double.

We can say that what Tesla did in electronics, Constantinescu succeeded in mechanics. Share on Facebook Share.
