Kulbaka A. Computer aided design of wind- energy plant with vertical axis of rotor rotation

The work is dedicated to the development of computer aided design theory of wind- energy plant (WEP) with vertical axis of rotor rotation. It's substantiated the necessity the design of wind- energy plants with verti-cal axis of combined rotor rotation that provides their functioning at the pres-ence of weak winds, that it's typically for the territory of Ukraine. It's determined the more general decomposition of WEP design. Due to that the system of WEP is described by very big quantity of variable parameters, that complicates the criteria and functional restrictions calculations then the problem of WEP design is divided at the stages by introduction of de-sign description by levels of working out in detail. That's why, the solution of general task of WEP optimal design is given as the process of consecutive solu-tion of optimization local interrelationship problems, which are located at the different levels of hierarchy: selection of type of acceleration and main rotors, determining the amount of acceleration rotors and their locations with respect to the core, determining the amount of acceleration and the main rotor blades, the optimum range of profiles of the blades accelerating and main rotors, the opti-mal choice of design of the blades with the determination of optimal composite material which is made blade, determining the optimal geometric parameters of the combination of the rotor based on the use of mathematical models of aero-dynamics, strength-based criteria and a variety subject to the restrictions and solving the problem of multi-criteria optimization. It is shown that in order to reduce costs it is advisable to develop integrated CAD, partially using the existing system design, based on the application of the proposed optimization method.
