Design of the UAV aerodynamics in multiple stages

Autor: Popović Lazar S., Paunović Lazar D., Đilas Veljko S., Milutinović Aleksandar M., Ivanov Toni D., Kostić Ivan A.

Publikováno v: Scientific Technical Review, Vol 70, Iss 2, Pp 9-16 (2020)

This paper presents a methodology for aerodynamic optimization of UAV with VTOL capabilities. Aircrafts such as these usually fly at low speeds and due to that low Reynolds numbers are to be expected. The friction drag is highly dependent on the qual

Multi-objective constrained optimizations of VAWT composite blades based on FEM and PSO

Autor: Svorcan Jelena, Trivković Zorana, Ivanov Toni, Baltić Marija, Peković Ognjen

Publikováno v: FME Transactions, Vol 47, Iss 4, Pp 887-893 (2019)

Vertical-axis wind turbines (VAWTs) are attractive tools for wind energy extraction particularly suitable for small consumers or off-grid areas. Although their geometry is simple (here, rectangular blade of constant airfoil is assumed), aerodynamic a

Estimation of wind turbine blade aerodynamic performances computed using different numerical approaches

Autor: Svorcan Jelena, Peković Ognjen, Ivanov Toni

Publikováno v: Theoretical and Applied Mechanics, Vol 45, Iss 1, Pp 53-65 (2018)

Although much employed, wind energy systems still present an open, contemporary topic of many research studies. Special attention is given to precise aerodynamic modeling performed in the beginning since overall wind turbine performances directly

VAWT optimization using genetic algorithm and CST airfoil parameterization

Autor: Ivanov Toni D., Simonović Aleksandar M., Svorcan Jelena S., Peković Ognjen M.

Publikováno v: FME Transactions, Vol 45, Iss 1, Pp 26-31 (2017)

Darrieus type vertical axis wind turbine (VAWT) is optimized using the genetic algorithm (GA). The airfoil shape is parameterized using the Class-Shape Transformation (CST) method. The double multiple stream tube (DMST) method with the Gormont dynami
