Experimental checking of reversibility theorem for axially symmetric body with empennage
(Osvita Ukrainy, 2016-12) Tupitsin, Nikolay; Тупіцин, Микола Федорович; Ziganshin, Anwar; Зіганшин, Анвар Абдуллович; Stepanenko, Illia; Степаненко, Ілля Олександрович
Wind tunnel tests were implemented for experimental verification of the reversibility theorem for three various shapes of fore body for an axially symmetric thin body in direct and reverse streams. Be- sides, such tests were implemented for UAV models with three types of wings. Results of investigations showed that the error of execution reversibility theorem consequence can achieve 12.5% at the range of angles of attack from 0 to 20° (accordingly, from 180° to 200°).
Experimental investigation of wind energy plant with helicoidal rotor
(National Aviation University, 2019-12-26) Sineglazov, Viktor; Синєглазов, Віктор Михайлович; Daskal, Evgen; Даскал, Євген Вікторович; Ziganshin, Anwar; Зіганшин, Анвар Абдуллович
The article is devoted to design and investigation of a helicoidal wind rotor in the wind tunnel, which is a modification of the Darrieus rotor – the most promising rotor type for vertical axis wind turbines. The graphs of power and rotation of the investigated wind generator depending on the incoming air flow speed are obtained. Investigation of the helicoidal rotor in a large wind tunnel has shown that the helicoidal rotor type has a high potential for use in vertical axis wind turbines. The high cut in speed of the incoming air flow is caused by the phenomenon of "sticking" of the axial generator with steel cores, as well as by the absence of an additional starting Savonius rotor, which could create the initial torque moment at rhe low speed of the incoming air flow.Iit is necessary to enlarge diameter of the generator and to reduce the air gap between the magnets and the stator to increase electric power.
