The Application of Analytical Methods to the Study of Pareto - Optimal Control Systems
Engineering Education # 04, April 2014
DOI: 10.7463/0414.0704897
Analytical approach to a problem of the multicriteria optimization, being alternative to expensive cost calculation numerical methods of sounding of space of parameters is considered. The statements allowing on characteristics of a comonotonicity and contramonotonicity are formulated and to the angular characteristic of anti-gradients to define парето - optimum decisions. The received results are applied to a problem of parametrical synthesis of double-circuit control systems by movement of missilies. The possible directions of improvement of inconsistent criteria of time of increase and reregulation are shown and limits of parametrical correction are noted

Method of calculating aerodynamic characteristics of bodies with arbitrarily curved axis

Engineering Education # 11, November 2012
DOI: 10.7463/1112.0492155
The study of aerodynamics of bodies that received permanent deformation in the process of movement is a very important task. The authors developed an efficient matrix method for describing the geometry of bodies with an arbitrarily curved axis; this method was used as the basis for creating a general method for calculating aerodynamic characteristics of such bodies; this general technique is based on the physical "Newtonian inhibition" hypothesis. This approach allows to calculate not only aerodynamic but inertial characteristics of curved bodies; also it can serve as a basis for formation of a combined method of deformed bodies with head and tail surfaces.
77-30569/249741 Studying special features of aerodynamics of curved bodies
Engineering Education # 11, November 2011
Studying aerodynamics of bodies which received irreversible deformations in the process of motion is an extremely urgent task today. The authors analyze the approaches used in studying flow around elongated bodies at high angles of attack. The authors provide a general formula for a body with constant curvature of direct axis. The authors give primary attention to the description of original experimental studies of flow near a curved body at supersonic speeds. The results of the visualization of flows and drainage studies are given. The authors justify the proposals on modifications of the Newton theory of flow and other theories for creating a method of calculating aerodynamic characteristics of random deformed bodies.
