George Constantinescu, a genial inventor of the twentieth century

George (or Gogu) Constantinescu (1881 - 1965) was a Romanian scientist, engineer and inventor. During his career, he registered over 130 inventions. He is the creator of the Theory of Sonics, a new branch of continuum mechanics, in which he described the transmission of mechanical energy through vibrations.

Born in Craiova and settled in the United Kingdom from 1912, Constantinescu was an honorary member of the Romanian Academy.

Among his inventions are a mechanical torque converter, a sonic engine and a hydraulic machine-gun synchronizer (or interrupter gear) - which allowed airplane-mounted-guns to shoot between the spinning blades of the propeller). The Constantinesco synchronization gear (or "CC" gear) was first used operationally on the D.H.4s of No. 55 squadron R.F.C. from March 1917, during World War I, and rapidly became standard equipment, replacing a variety of mechanical gears. It continued to be used by the Royal Air Force until World War II - the Gloster Gladiator being the last British fighter to be equipped with "CC" gear.

He was the designer of the Constantinesco, a French-manufactured car, and of the Constanţa Mosque (a project completed by the architect Victor Ştefănescu).

Although GEORGE CONSTANTINESCU's work is invaluable, it was not known enough, because of the secret given by the military mainly uses and on the other hand the few publications on this. Thus, his first book published in 1918 in London, in a limited number of copies, has been declared secret by the British government, because the explanations that have new theory in the field of weapons and means of war.

GEORGE CONSTANTINESCU's recognition internationally is certified by the British magazine published a picture "The Graphic" in 1926, featuring the presentation of scientific illustrious personalities of the time, starting with Einstein, Edison, Kelvin Howard Walter Florey (first row of second), Rutherford, Marie Curie, etc..
