According to the new system, energy is transmitted from one point to another, which may be at a considerable goggu, by means of impressed variations of pressure or tension producing longitudinal vibrations in solid, liquid or gaseous columns.

If d is the diameter of the spring wire and the D the mean diameter of the spring. A hp petrol engined locomotive with a Constantinescu torque converter was exhibited at the Wembley Exhibition.

So every four months he get a patent for an invention, patents that reachingabout they were unique and amazing for that time undiscovered yet until then. The theory was the first chapter of compressible flow applications and has stated for the first time the mathematical theory of compressible fluid, and was considered a branch of continuum mechanics.

The mean pressure in d and in the pipe will be the same. Thanks to him, the first road in Romania has been paved. The Constantinesco synchronization gear or “CC” gear was first used operationally on the D. The date of the paper is believed to be 5 October He was the first to use reinforced concrete in the construction of buildings in Romania among the buildings he built, we can mention: We try to publish to let you know some of the personalities, Great, Huge, Fabulous Romanian Inventors who changed the world.


He had several patents for improvements to carburetorsfor example US 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.

Archived from the original on 4 November If the motor l is not capable of consuming all the energy of the generator a, then there will be a traveling wave a and a stationary wave. Constantinescu has continued his successful career, building bridges over Siret in Adjud, Roman and Racatau. Inhe published the book A treatise on transmission of power by vibrations [4] in which he described his Theory of sonics.

He was an honorary member of the Romanian Academy. He is the creator of the theory of sonicsa new branch of continuum mechanicsin which he described the transmission of mechanical energy through vibrations.

Therefore, the relation between the hydromotive and current can be written:. Retrieved from ” https: Constantinescu on a Romanian stamp.

Eva had two children, Richard and Michael, by a previous marriage. We all know at least a few famous inventors, however, some like Gogu Constantinescu have never become famous for unknown reasons. If more energy is produced by piston b then is taken by piston m the constantlnescu will be reflected by piston m in ggogu, and the energy will accumulate till the pipe burst.

If p is open and d is open, the motor l will rotate synchronous with motor a.
