A Treatise on Transmission of Power by Vibrations. Inertial Transmission US Patent etc “. Hydraulic constantineecu are appliances for making alterations in value of fluid currents, pressures or phases of alternating fluid currents.

He had several patents for improvements to carburetorsfor example US The mean pressure in d and in the pipe will be the same.
The laws discovered by Constantinescu, used in sonicity are the same with the laws used in electricity. If p 1 is coonstantinescu pressure at an arbitrary point and p 2 pressure in another arbitrary point:. The most constzntinescu findings are; — the asphalt, modern consantinescu 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.
Please help to improve this article by introducing more precise citations. During his years as a student, he has promoted the usage of steel reinforced oggu to his students. Gogu Constantinescu was one of those brilliant minds, whose ideas have long outstripped his physical existence, but which today preserves its topicality, surprising by its accuracy, inventiveness and applicability.
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. Share on Facebook Share. Wikimedia Commons has media related to George Constantinescu.
The latter ran on normal flanged steel wheels but the drive used a road vehicle powertrain with rubber tyres pressed against the rails.
Other inventions included a “railway motor wagon”. He is the creator of the theory of sonicsa new branch of continuum mechanicsin which he described the transmission of mechanical energy through vibrations. Born in Craiova in “the Doctor’s House” near the Mihai Bravu Gardens, he was influenced by his father George, born in a professor of mathematics and engineering science, specialized in consyantinescu at the Glgu University.
We try to publish to let you know some of the personalities, Great, Huge, Fabulous Romanian Inventors who changed the world.
His father born in ,influenced him, being a professor of mathematics and engineering science, specialized in mathematics at the Sorbonne University. This is similar to the system used goggu many modern road-rail vehicles.
Suppose the crank a to be rotating uniformly, causing the piston b to reciprocate in the pipe c, which is full of liquid. Although Constantinescu gofu 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. Use dmy dates from July Articles lacking in-text citations from March All articles lacking in-text citations. Share on Pinterest Share.
The effective hydromotive force will be: At next rotation the amplitude is increased, and so on, till the pipe burst. Share on Digg Share. The Admiralty, London, Simple Harmonic The principal function of hydraulic condensers is to counteract inertia effects due to moving masses.
It was also tried on rail vehicles. If more energy is produced by piston b then is taken by piston m the energy will be reflected by piston m in pipe, and the energy will accumulate till the pipe burst. He was an honorary member of the Romanian Academy. Did you know that? The birth of the theory of sonics  can be considered the publication of the book Constntinescu treatise on transmission of power by vibrations in by the Romanian scientist Gogu Constantinescu.
The apparatus usually consists of a mobile solid body, which is dividing the liquid column, and fixed elastically in a middle position, in such way that it follows the movements of the liquid column. Retrieved constantinescuu July Born in Craiova, Romania — year — october 4th day — Past away Coniston Water, England, yeardecember 11 th. If only valve c is open, since at this point the variation of pressure is always zero, no energy can be taken out by the motor n, and the stationary wave will persist.
The methods of transmitting power known and practised by engineers are broadly included in two classes: March Learn how and when to remove this template message. A Treatise on Transmission of Power by Vibrations. Inhe published the book A treatise on transmission of power by vibrations  in which he described his Theory of sonics. 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, oil, various liquids, air, gas, or full bars.
From Wikipedia, the free encyclopedia. Most of his discoveries constantinesfu could be public because were kept top secret by British ministery of defense ,and were about military technology,about plains and strategic weapons. While Gogu Constantinescu has invented many useful things around inventions which have been patented all over the worldhe has mostly worked towards a successful usage of steel reinforced concrete.

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. Share on Google Plus Share. Retrieved from ” https: If gogk 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.
The theory of sonics is a branch gohu continuum mechanics which describes the transmission of mechanical energy through vibrations. American Journal of Engineering and Applied Sciences. The pipe is closed at p, a distance of one complete wavelength. This page was last edited on 12 Juneat
