Artificial neural network for the evaluation of electric propulsion system in unmanned aerial vehicles Goli, Srikanth; Kurtuluş, Dilek Funda; Waqar, Muhammad; Imran, Imil Hamda; Alhems, Luai M.; Kouser, Taiba; Memon, Azhar M. (2025-01-01) In the domain of unmanned aerial vehicles (UAVs), evaluating electric propulsion systems is pivotal for enhancing performance and efficiency. This study employs a scaled conjugate gradient (SCG) algorithm to train an artif...
Design optimization of a fluidic thrust vectoring system based on coanda effect using meta-models Kara, Emre; Kurtuluş, Dilek Funda (2024-12-30) In this study, parametric optimization is employed to identify optimal output parameters for physical components of HOMER nozzle type fluidic thrust vectoring (FTV) system. Optimization study is conducted on seven output p...
The oscillating vortex generator: a boundary layer propulsion and flow control device Anılır, Berkan; Kurtuluş, Dilek Funda; Platzer, M. F. (2024-11-29) This paper aims to explore the feasibility of providing boundary layer propulsion and flow control by means of embedded aerofoils that are oscillating in the pure plunge mode. To this end, Navier-Stokes calculations of the...
Experimental and Numerical Unsteady Aeroelastic Effect Analysis of Wing Model Triggered with Piezoelectric Material Comez, F.Y.; Sengil, N.; Kurtuluş, Dilek Funda (2024-01-01) The current study analyzed the piezoelectrically driven mechanism responsible for generating force in both rectangular and hummingbird wings, which mimicked the flapping motion of the micro air vehicles, utilizing a combin...
Distributed Robust Formation Control of Heterogeneous Multi-UAVs with Disturbance Rejection Imran, Imil Hamda; Kurtuluş, Dilek Funda; Memon, Azhar M.; Goli, Srikanth; Kouser, Taiba; Alhems, Luai Muhammad (2024-01-01) This paper investigates the formation control of multiple heterogeneous quadrotor unmanned aerial vehicles (UAVs). The research focuses on developing a distributed robust formation control strategy to effectively manage th...
Unsteady aerodynamics over NACA0005 airfoil for ultra-low Reynolds numbers Kouser, Taiba; Kurtuluş, Dilek Funda; Aliyu, Abdulrahman; Goli, Srikanth; Alhems, Luai M.; IMRAN, Imil Hamda; Memon, Azhar (2024-01-01) Numerical simulation for a two-dimensional NACA0005 is performed for angle of attack α = 0° − 15° in present study. The Reynolds numbers 1000, 2000 and 5000 are considered. Simulations show that...
Implementation of a new actuator disc model based on BEM theory in SU2 CFD software Yenipazar, Kaan; Kurtuluş, Dilek Funda (2024-01-01) The aim of the current study is to develop an alternative actuator disc model in the SU2 (Stanford University Unstructured) software using the blade element theory (BEM) approach. The objective is to reduce computational c...
Three-dimensional flow evaluation of monarch butterfly wing Comez, Fadile Yudum; Sengil, Nevsan; Kurtuluş, Dilek Funda (2024-01-01) The current study aims to examine the flow field around a monarch butterfly wing at different angles of attack. A fully opened forewing configuration for the monarch butterfly wing has been selected for analysis at a maxim...
