A variation problem on shapes of planar, axisymmetric, and spatial bodies which are optimal for minimizing the convective and radiation heat of their surfaces under hypersonic flowstreaming was stated and solved. Analytic and numerical solutions were obtained for diverse variation problems on optimal shapes of bodies and their flight trajectories in the atmospheres of the Earth and other planets. A problem on finding the rate constants of nonequilibrium reactions via measurements in hypersonic flow near the flying body was stated for the first time. Numerous solutions of inverse problems were obtained via measurements in ballistic Experiments. New theoretical expressions were obtained for the coefficients of triple recombination with electrons which essentially complement the well-known formulae by Pitaevsky and Langevin.
Biography
Graduated from Faculty of Theoretical Nuclear Physics of Moscow Engineering-Physical Institute in 1966 (department of theoretical physics). Ph.D. thesis was defended in 1973. D.Sci. thesis was defended in 1992. A list of my works contains more than 195 titles.
20 young scientists have defended their Ph.D. thesis" under my advisorship.
In 1986 I was awarded the prize of the Ministry of Higher Education of the USSR for a series of papers on the gasdynamical flows in turbulent wakes behind bodies flying with hypersonic velocities (jointly with S. G. Tikhomorov and N. N. Baulin). In 1993 I was awarded the N. E. Zhukovsky prize (with presenting the silver medal) for a series of papers on nonequilibrium flowstreaming around bodies (jointly with V. S. Khlebnikov and R. F. Talipov). In 1993 I was awarded the prize of the publishing company "Nauka" for the best publication of the year for a series of papers on inverse problems in nonequilibrium gasdynamics.
In 1998 I was awarded the P. L. Kapitsa medal by the Presidium of the Russian Academy of Natural Sciences for the fundamental contribution to the research of nonequilibrium flows.
In 1994 I was elected member of the New York Academy of Sciences.
In2001, at the VIII All-Russian congress on mechanics, I was elected member of the National Committee on Theoretical and Applied Mechanics.
