    Purpose: The article researches the actual issues of developing partnership and cooperation between the state and private business in matters of production and modernization the military-industrial complex of Russia. The main object of the research is the Russian NAVY. The subject of the research is the comparison of the Russian and US NAVY modernization in the context of public and private partnership. Design/Methodology/Approach: The authors used a wide range of methodological tools in the course of the study. The method of economic analysis, the method of structural analysis, the statistical method and the method of mathematical comparison were used. Findings. Studying the role of business actors in the national rearmament programmes in Russia the authors revealed such key indicators as economic viability and financial efficiency of programme implementation. A comparative analysis of budget and private funding of the similar US programme was conducted and statistical data supporting the main findings of the study were introduced. Practical Implications: The development of cooperation between business and the MIC at the state level should go along the path of creating conditions for public-private partnerships (PPPs) - a set of organizational, legal, financial and economic relations and joint actions of the state and private business aimed at achieving the goals of the state economic policy in order to address socially significant tasks on mutually beneficial conditions. Originality/Value: The authors’ conclusion that state’s financial and economic policy in the field of defense and modernization of the domestic defense industry has all chances to become the locomotive of the country’s industrial, scientific and technological development gives new horizons for discussing the most appropriate rearmament strategy.peer-reviewe

    Nonlinear Feedback Control of Axisymmetric Aerial Vehicles

    Get PDF
    We investigate the use of simple aerodynamic models for the feedback control of aerial vehicles with large flight envelopes. Thrust-propelled vehicles with a body shape symmetric with respect to the thrust axis are considered. Upon a condition on the aerodynamic characteristics of the vehicle, we show that the equilibrium orientation can be explicitly determined as a function of the desired flight velocity. This allows for the adaptation of previously proposed control design approaches based on the thrust direction control paradigm. Simulation results conducted by using measured aerodynamic characteristics of quasi-axisymmetric bodies illustrate the soundness of the proposed approach

    Wind Field and Trajectory Models for Tornado-Propelled Objects

    A mathematical model to predict the trajectory of tornado born objects postulated to be in the vicinity of nuclear power plants is developed. An improved tornado wind field model satisfied the no slip ground boundary condition of fluid mechanics and includes the functional dependence of eddy viscosity with altitude. Subscale wind tunnel data are obtained for all of the missiles currently specified for nuclear plant design. Confirmatory full-scale data are obtained for a 12 inch pipe and automobile. The original six degree of freedom trajectory model is modified to include the improved wind field and increased capability as to body shapes and inertial characteristics that can be handled. The improved trajectory model is used to calculate maximum credible speeds, which for all of the heavy missiles are considerably less than those currently specified for design. Equivalent coefficients for use in three degree of freedom models are developed and the sensitivity of range and speed to various trajectory parameters for the 12 inch diameter pipe are examined

    An improved version of the Adaptive Maneuvering Logic (AML) program for air-combat maneuvering is discussed. The modifications and improvements incorporated into the AML program are documented

    US and USSR Military Aircraft and Missile Aerodynamics 1970-1980. A selected, annotated bibliography, volume 1

    Get PDF
    The purpose of this selected bibliography (281 citations) is to list available, unclassified, unlimited publications which provide aerodynamic data on major aircraft and missiles currently used by the military forces of the United States of America and the Union of Soviet Socialist Republics. Technical disciplines surveyed include aerodynamic performance, static and dynamic stability, stall-spin, flutter, buffet, inlets nozzles, flap performance, and flying qualities. Concentration is on specific aircraft including fighters, bombers, helicopters, missiles, and some work on transports, which are or could be used for military purposes. The bibliography is limited to material published from 1970 to 1980. The publications herein illustrate many of the types of aerodynamic data obtained in the course of aircraft development programs and may therefore provide some guidance in identifying problems to be expected in the conduct of such work. As such, this information may be useful in planning future research programs
