Andrey Vladimirovich

Andrey Vladimirovich Rimsky-Korsakov, grandson of the famous Russian composer, was born on August 29, 1910, in St. Petersburg to a family of ancient noble lineage. His father had two master university degrees, and his mother graduated from the Smol'nyi Institute. French was accepted as the main language amongst family members.

Andrey Vladimirovich received an excellent education: he simultaneously studied at a German general education school and at a music school. After graduating, he began studies at the Leningrad Conservatory and the Leningrad Polytechnical Institute.

This combination of musical education and technical knowledge allowed Andrey Vladimirovich to work successfully at the Research Institute of Musical Industry organized by Academician N.N.Andreyev.

There, since 1932, he collaborated with A.A.Ivanov to construct one of the first Russian electric musical instruments: the Emiriton. While heading the laboratory of string musical instruments, Rimsky-Korsakov investigated sound formation in pianos, pizzicato musical instruments, and bow instruments.

In 1940, for his studies of string and sounding-board vibrations in musical instruments, Rimsky-Korsakov received a candidate degree.

In early 1941, Rimsky-Korsakov changed his place of work and came to the Leningrad Physicotechnical Institute of the Academy of Sciences of the USSR, where he began his investigations in hydroacoustics.

In 1942, he joined the Navy and, during the war, he was involved in designing and testing acoustic mines. After he was demobilized, Rimsky-Korsakov returned to his studies in musical acoustics.

The 1946 marked the beginning of Rimsky-Korsakov's tutorial activities---first, as an associate professor at the Department of Broadcasting and Acoustics at the Leningrad Electrotechnical Institute of Communication, and then, as the head of this department and the dean of the Faculty of Radio Engineering.

In 1950, Rimsky-Korsakov received his Doctoral Degree and the title of Professor.

In 1955, Rimsky-Korsakov moved to Moscow and became the head of the department that he organized himself at the Acoustics Institute of the Academy of Sciences of the USSR. There, he conducted extensive studies in noise and vibrations of complex mechanical structures, as well as in aeroacoustics and hydroacoustics.

The studies of noise formation in a gas flow streaming around obstacles allowed Rimsky-Korsakov and his colleagues to reveal a number of new mechanisms of sound formation by vortices and by rotating fans and blade wheels.

On the basis of these studies, they worked out recommendations for the design of low-noise turbocompressors and centrifugal ventilators. Rimsky-Korsakov and his co-workers developed methods of calculating the noise fields of jet engines and proposed ways for suppressing the self-excited vibrations of powerful jets. They undertook studies of noise radiation from submerged gas jets, both cool and heated, flowing freely to the atmosphere or to ejectors. They also determined the specific features of the generation of discrete components in the noise of choked jets and proposed a resonance technique for their control.

Important results were obtained by Rimsky-Korsakov and his colleagues in studying noise excited in frame structures by the mechanisms they support. These studies were performed by the method of acoustic simulation of structural vibrations. In collaboration with the researchers from the Institute of Mechanical Engineering of the Academy of Sciences of the USSR, Rimsky-Korsakov worked on the development of efficient vibration-proof basement structures and active electromechanical damping of vibrating mechanisms.

In 1960, Rimsky-Korsakov established the Department of Electroacoustics and Ultrasonics at the Moscow Mining Institute. At this department, he delivered lectures on electroacoustics, acoustical measurements, and noise and vibration control and supervised the studies of the possibility of intensifying technological processes by applying low-frequency acoustic vibrations.

Since 1965, Rimsky-Korsakov taught at the Moscow Institute of Radio Engineering, Electronics, and Automation: he gave lectures on electroacoustics, organized a student's training laboratory, published a monograph on electroacoustics and a companion book of problems.

Rimsky-Korsakov is the author of 9 monographs on different fundamental problems of acoustics. He is also the editor of five collections of papers on acoustical aerodynamics and on vibrations of mechanical structures. He owns more than fifty inventor's certificates.

Among his former students, there are 20 candidates and 2 doctors of science. His list of publications contains more than 100 scientific works.

Rimsky-Korsakov has given many invited and plenary talks at international scientific conferences in Moscow, Tokyo, Budapest, Madrid, and London. He represented the USSR in the International Electrotechnical Commission as secretary of the Ultrasound Subcommittee. He was also a member of the International Commission on Acoustics.

For his achievements in science, Andrey Vladimirovich Rimsky-Korsakov was awarded high state awards: the Badge of Honor, Order of the Red Banner of Labor, and medals.
