Moscow Aviation Institute founded in 1930 is one of several major engineering higher education establishments in Moscow. Since its inception MAI has been spearheading advances in aerospace technology both within Russia and worldwide. The university laid emphasis on laboratory instruction in applied science and engineering, specific to demands of the aerospace industry. During World war II part of the university was evacuated to Almaty Kazakhstan, the university, staff and students continued to work on research and wartime production throughout the war.During the Post-War period, the university expanded and assimilated new technologies during the Jet age. Research conducted in the university contributed to heralding the space age.The university has to its merit more than 160000 specialists, 250 chief designers in the Aerospace Industry. 50 Academicians of the Russian Academy of science, 22 cosmonauts, 100 test pilots and 60 Olympic champions in different sports.Alumni of the institute form the backbone of many companies like Sukhoi, MIG, Ilyushin, Tupolev, Yakovlev, Beriev, Myasishchev, Mil Moscow Helicopter Plant, OAO S.P. Korolev Rocket and Space Corporation Energia, Lavochkin, Makeyev Rocket Design Bureau, Khrunichev State Research and Production Space Center, NPO Energomash, Almaz-Antey and others. Wikipedia.

We study the unique solvability of the Steklov problem for the biharmonic equation in unbounded domains under the assumption that a generalized solution of this problem has a bounded Dirichlet integral with weight |x|a. Depending on the value of the parameter a, we prove uniqueness theorems or present exact formulas for the dimension of the solution space of the Steklov problem in the exterior of a compact set and in a half-space. © 2017, Pleiades Publishing, Ltd.

The main objective of RESEARCH project is the definition of an electrical architecture for Flight Control System capable of controlling a flight control surface on an Aircraft with the help of electrically operated actuators, thus replacing the hydraulic actuators commonly used in current Aircraft designs. This architecture will be designed with the main objective of being electrical, as this is the main purpose of this call, and certifiable, since the intention is to be able to use it in a possible future Aircraft. The objective of the RESEARCH project is to find a robust architecture to meet the constraints imposed by safety regulations while keeping other system performances (as weight, Reliability) as optimal as possible.

A comparative analysis of predictive ability of three approaches to estimate the rate constants of reactions of H2, H, H2O and CH4 with electronically excited O2(a1Δ g) and O2(b1Σ+g) molecules is conducted. The first approach is based on a detailed ab initio study of potential energy surfaces. The second one is known as the "bond energy-bond order" method, and the third approach is a modification of the updated method of vibronic terms that makes it possible to evaluate the activation energy of reactions involving electronically excited species. The comparison showed that the estimates of the energy barrier by the updated method of vibronic terms for some reactions can be in good agreement with ab initio calculations and available experimental data. It was revealed that reactions of O 2(b1Σ+g) molecules with H2, H 2O and CH4 molecules and with the H atom result in the formation of electronically excited species. The reactivity of O 2(b1Σ+g) molecules is smaller than that of O 2(a1Δg) ones, but much higher as compared to the reactivity of ground state O2 molecules. For each reaction under study involving oxygen molecules in the excited electronic states O 2(a1Δg) and O2(b 1Σ+g) the recommended temperature-dependent rate constants are presented. © 2011 the Owner Societies.

We consider the design features of fan noise suppressors in application to air intakes and the bypass duct of a turbofan engine. A combined liner is developed that has increased acoustic efficiency in comparison to conventional honeycomb liner . We demonstrate the important role of the area of the sound-absorbing liner between fan Rotor and Stator ensuring significant noise reduction. © Pleiades Publishing, Ltd., 2012.

A high-resolution technique of large eddy simulation with the implicit subgrid model (ILES) is presented for computation of compressible turbulent flows. The technique is applied to computation of jet flows. The nozzle and jet flows were computed jointly for obtaining realistic flow parameters at the nozzle exit section. Two approaches to the flow simulation in the boundary layer and in the nozzle are considered. The Reynolds-averaged Navier-Stokes (RANS) equations are used for the boundary layer description in the first approach. For the RANS/ILES method, the influence of the order of difference approximation of convection terms in the Navier-Stokes equations on the resolvability of the developed method is shown. The computa-tions were performed for subsonic and off-design supersonic jets on a grid containing 1.1 × 106 cells. It is found that an increase in the order of the difference approximation from five to nine enables the accuracy of results to be improved without increasing the number of computation grid cells. The high workability of the method is demonstrated for computation of supersonic flows with separations. In the second approach, the largest eddies in the boundary layer were resolved explicitly, and the flow near the wall was described by the simplified wall model (WM). Use of the WMILES method for joint computation of the nozzle and jet flows made it possible to refine the description of the turbulent mixing layer near the nozzle exit section and improve the accuracy of agreement with the experiment. The flows in different-shape chevron nozzles and their jets were jointly computed using the WMILES method on the grids with (2.3-2.5) × 106 cells. The agreement of the computations with the experiment for the level of maximum fluctuations in the mixing layer was improved appreciably as compared to the computations using the RANS/ILES method. A possible expla-nation is found for the growth in high-frequency noise in the investigated chevron nozzles, which is observed in the experiment. © Pleiades Publishing, Ltd., 2012.

Two classes of MIMO radars are briefly considered. MIMO radars with colocated antennas and coded signals represent a new and prospective concept. MIMO Radars with widely separated antennas ("Statistical MIMO radars") are a particular case of well-known Multisite (Multistatic) radar systems. Most results presented by the authors of "Statistical MIMO radars" were obtained under much more general conditions and published many years ago. Besides, ignoring some specific features of radar by the authors of "Statistical MIMO radars" has led to serious errors. © 2010 EuMA.
