Views Read Edit View history. The laws discovered by Constantinescu, used in sonicity are the same with the constantinscu used in electricity. If p 1 is the pressure at an arbitrary point and p 2 pressure in another arbitrary point:.

His hydraulic machine gun synchronization gear allowed airplane-mounted guns to shoot between the spinning blades of the propeller. 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. 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. According to the new system, energy is transmitted from one point to another, which may be at a considerable distance, by means of impressed variations of pressure or tension producing longitudinal vibrations in solid, liquid or gaseous columns.

The energy is transmitted by periodic changes of pressure and volume in the longitudinal direction and may be described as wave transmission of power, or mechanical constantinwscu transmission. The pipe is closed at p, a distance of one complete wavelength.

Suppose the crank a to be rotating uniformly, causing the piston b to reciprocate in the pipe c, which is full of liquid.

Theory of sonics

From Wikipedia, the free encyclopedia. The theory is applicable to various systems of power transmission but has mostly been applied to hydraulic systems. Retrieved 24 July In he has also published materials on its usage, calculus and he has tested the usage of this material in arch bridges. 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.


A hp petrol engined locomotive with a Constantinescu torque converter was exhibited at the Wembley Exhibition. Please help to improve this article by introducing more precise citations. The latter ran on normal flanged steel wheels but the drive used a road vehicle powertrain with rubber tyres pressed against the rails.

We can say that what Tesla did in electronics, Constantinescu succeeded in mechanics. Archived from the original on 4 November 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 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. 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 result of reflected waves will be a stationary wave in pipe with no increase of energy, and the pressure in the pipe will never exceed the pressure limit.

Archived from the original on fonstantinescu July He was responsible for creating a new field of mechanics, called consrantinescu which describes the gkgu of energy through vibrations in fluid or solid bodies. Waves are transmitted by a reciprocating piston along the pipe eeee. His father born in ,influenced him, being a professor of mathematics and engineering science, specialized in mathematics at the Sorbonne University. The theory of sonics is a branch of continuum mechanics which describes the transmission of mechanical energy through vibrations.


George “Gogu” Constantinescu Romanian pronunciation: 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. Constantinescu has studied at the Bridges and Roads School in Among other achievements, there is also a pulling device among the propeller blades regardless of its speed and the first automatic gearshift.

This article consantinescu a list of referencesbut its sources remain unclear because it has insufficient inline citations. The alternating pressures are very similar with alternating currents in electricity.

George Constantinescu

The Constantinesco synchronization gear or “CC” gear was first used operationally on the D. Use dmy dates from July Yogu lacking in-text citations from March All articles lacking in-text citations.

He has actively participated in the construction of English aircraft, the Bristol type, while he lived in England. 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. In alternating current flowing a pipe the friction appear at the surface of the pipe and also in liquid itself.

Did you know constantinesdu In a pipe were the currents are flowing, we will have:. While Gogu Constantinescu has invented many useful things around inventions which have been patented all over the worldhe consfantinescu mostly worked towards a successful usage of steel reinforced concrete. It was also tried on rail vehicles. This page was last edited constxntinescu 9 Octoberat
