Muravyts'kyj O. Development of techniques for rational designing of units of the flying devices from composite materials

The dissertation is devoted to questions of rational designing the fuselage and panel of a wing as designs of flying devices made by winding from composite materials, and also structure composite materials in view of constructive - technological restrictions. In the dissertation the system of analytical dependences for an estimation of a realizability fiber-reinforcing of the layers of composite materials on trajectories of main stresses connecting external loading, physical and mechanical properties of materials of the layers and fiber-reinforcing angle is received. The techniques and software on PC for designing optimum fuselage and panels of a wing of minimal weight are developed with nonsymmetrical multialternative loading in view of technology factors of their manufacturing and opportunity of application of hybrid materials. The new scientific rules are offered about optimumum structure of layered composite materials with any flat loading
