• WIND POTENTIAL ANALYSIS FOR HAKKARI CENTRAL REGION

    Machines. Technologies. Materials., Vol. 12 (2018), Issue 7, pg(s) 283-286

    In this study wind potential investigated for the region to the east of Turkey’s Hakkari centers. The wind speed and direction information used in the study were taken from the measurement station belonging to the General Directorate of Meteorology in Hakkari Center. Data sets containing 5 year wind speed and wind direction between 2013 and 2017 taken from this measurement station were analyzed by the WASP program. The NASA SRTM data library in the WASP interface was used to create digital maps for the region. Regional barriers required for areas where wind potentials are searched and roughness maps were created using Google Maps. As a result of these analyzes, annual average wind speed value of 1.96 m / s and average power density of this region in Hakkari Center is calculated as 12 W / m2. The prevailing wind direction belonging to this region has been identified as Southwest, but it has been found that this dominant wind direction changes with great proximity to the Southeast-Northwest sector interval on the South side.

    NEW DESIGNS OF ROTORS WITH VARIABLE GEOMETRY PARAMETERS IN DYNAMICS AND THEIR EFFECTIVE USE IN AVIATION AND WIND ENERGY

    Machines. Technologies. Materials., Vol. 10 (2016), Issue 10, pg(s) 6-9

    In the report will be presented the investigation results of the working model of rotors with variable geometry parameters in dynamics. Because of aerodynamic and economic calculations, the effectiveness of use of such designs for powerful wind stations is proved. The analysis of various designs and methods of selection of that or other design for various conditions of operation of wind installations in wide range of the wind speed change is given.
    Also rather effective by cost-price method of accumulation of wind energy will be suggested that is the topical world problem and for development of which are annually spent some hundreds of millions of US Dollars.
