Georgy Vladimirovich Logvinovich graduated from the Moscow State University in 1935 as a hydraulic engineer and continued in practice until 1941, when being called to the Soviet Army. From 1945, he was a collaborator of TsAGI, the Soviet Central Aero-hydrodynamics Institute in Moscow, and he was from 1966 to 1971 director of the Institute of Hydromechanics at the Ukrainian Academy of Sciences in Kiev after having been a Lecturer at the Moscow Power Institute from 1957 to 1961, and where he was appointed professor in 1970. Logvinovich was elected Member of the Ukrainian Academy of Sciences in the 1970s. He was awarded the Lenin Premium in 1978.

Logvinovich remains known for studies relating to the movement of bodies with high speed, for which he derived a number of theorems relative to the free boundaries. He thus studied hydromechanical phenomena that occur during cavitation and analyzed both theoretically and experimentally the characteristics of fast moving bodies immersed in fluid. He also established that the acoustic energy dissipated by impact of a flat body onto a rigid boundary is independent of the speed of sound. He was also interested in the design of underwater wings for which he presented a general theory based on an infinite cavity. These studies were conducted in relation to propulsion of fish and other sea animals. Cavitation was further considered in relation to the internal flow structure in its cavities. Logvinovich was the founder of a school in hydrodynamics whose purpose is to investigate super-fast movements of bodies in a fluid environment.
