Abstract— Coal, oil and natural gas are the main pillar of effective industrial progress.

INTRODUCTION RADITIONAL energy sources as oil can be considered the major source to meet the world energy needs but quick depletion of oil are major concern. Clearly, this problem can be treated using clean renewable energy but improving its usage needs sufficient time to meet the future challenges [1]. Some developing countries in middle east region have little bit resources of conventional energies (coal, oil and natural gas) like Egypt. Moreover, a yearly expenditure of conventional energy resources increases rapidly in the developing countries. Developing secondary sources other than oil as wind energy must be the challenge of these countries for assuring the sustainability of energy supplies in the long term. More than 15% of the energy consumed across the world is produced from the renewable energy as wind, solar and sea waves [2]. Alternative energy resources as solar, wind and sea waves energies can fill the gap between the increasing demand and available energies in countries have poor in conventional Khaled M.

These wind turbines are classified into two groups, horizontal (HAWT) and vertical (VAWT) wind turbine axes. Structures of horizontal axis wind turbines are complicated and economically valuable only in areas having high speed winds throughout day time [3], [4]. Clearly, VAWT has a simple design and low operating and maintenance costs. Therefore, VAWT suitable for individual use specially in isolated areas like helping the young farmers in the desert for producing the electricity or directly driving a pumps to lift water from the wells. As well as, modeling and control of a new compressed air energy storage system is presented for offshore wind turbine in [5]. The vertical wind turbines of savonius blades have many advantages as the capability to work at low wind speed with a modest assembly [4], [6]. Many of pervious researches are dealing with the performance analysis of savonius rotor as [7]. Also, the performance and flow field assessment of a savonius rotor tested using a wind tunnel in [8]. Electricity can be generated using wind turbine system has one electric generator coupled to the rotors through a differential planetary system as presented in [9]. The requirement of increasing the maximum power which could be extracted from the air current by using counter rotating wind turbines introduced in [10]. A new ideas of wind turbine as floating offshore wind turbine concept introduced in [11], [12]. Also, increasing the savonius rotors efficiency through a parametric study presented in [13]. The calculation of the energy production of wind turbine presented in [14]. Dynamic analysis of a floating wind turbine of vertical axis presented in [15]. The numerical and analytical study of vertical axis wind turbine is presented in [16]. Many researches are dealing with improving the wind turbine performance using light composite materials for manufacturing the turbine blades as in [17], [18]. As well as, shaft torsion in addition to blade bending coupling vibrations in a rotor system are discussed in [19]. Many researches are dealing with investigation of theoretical and experimental results through testing an experimental prototype as [20], [21]. This paper is dealing with improving the wind turbine performance using light composite materials blades and rotor (shaft) with a very low corrosion and wear problems. Also, this paper seeks to enhance investigation of theoretical and experimental results through using a suitable experimental small prototypes.

Abstract— Coal, oil and natural gas are the main pillar of
effective industrial progress. Cheap renewable energy is attracting
most countries attention specially the developing countries for filling
the gap between their demand and available sources. Obviously,
shortage of traditional energy sources can be treated using wind
energy.
This paper gives a comprehensive overview of small vertical wind
turbine which suitable for countries have a moderate wind speed. The
wind turbine performance can be improved using composite materials
blades and rotor shaft. Also, corrosion and wear problems can be
treated using light wind turbine rotor and blades manufactured from
composite materials instead of using metal rotor and blades. As well
as, this paper seeks to enhance investigation of theoretical and
experimental results through using a suitable experimental two small
prototypes of vertical wind turbines. The first prototype has a
composite materials blades and shaft while the second prototype has
