George (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.
Among his inventions are a mechanical torque converter, a sonic engine and a sonic machine-gun synchronizer (aka interrupter gear) - which allowed airplane-mounted-guns to shoot between the spinning blades of the propeller). Constantinesco synchronization gear (or "CC" gear) was first used on the British Sopwith 1½ Strutter during World War I. It continued to be used by the Royal Air Force until the Second World War - the Gloster Gladiator being the last British fighter to be equipped with "CC" gear.
