In recent decades, researchers aim to understand and control the physical phenomenon behind the complex flow structure of low swept delta wings arising with their widespread use in Unmanned Air Vehicles (UAV), Unmanned Combat Air Vehicles (UCAV) and Micro Air Vehicles (MAV). In order to extend the working capabilities of these vehicles with having stable flight performance, detailed studies on understanding and controlling the flow structures over low swept delta wings are required. The aim of the present study is to control the flow structure over a non-slender delta wing with sweep angle of

Control of flow structure on 70° swept delta wing with along-the-core blowing using numerical modeling Küçükyılmaz, İbrahim Can; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2016) In recent years, interest has increased in Unmanned Combat Air Vehicles (UCAVs) and Unmanned Air Vehicles (UAVs), which can be represented by simplified planforms including delta wings. Delta wings experience the formation of two counter-rotating vortices on the leeward side of the planform due to the shear layer separated from the windward side. At sufficiently high angle of attack, these vortices undergo sudden expansion, called vortex breakdown/burst, which is quite detrimental considering the aerodynami...
Control of flow structure on low swept delta wing with staedy leading edge blowing Zharfa, Mohammadreza; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2014) Unmanned Combat Air Vehicles (UCAVs), Unmanned Air Vehicles (UAVs) and Micro Air Vehicles are becoming extremely popular due to introducing many advantages to defense industry and aeronautical field. In line with this, the aerodynamics of these vehicles, which can be represented by simplified planforms, including delta wings, have been of considerable interest in recent years. This interest has stimulated investigation of the flow structure, as well as its control, on delta wings having low and moderate val...
Development and implementation of novel flow control techniques for nonslender delta wings Çelik, Alper; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2017) Understanding and controlling the physical phenomenon behind the aerodynamics of low to moderate swept delta wings has been a challenge for researchers during the last few decades, which is stimulated by their widespread use in unmanned combat air vehicles (UCAVs) and micro air vehicles (MAVs). Although delta wings are capable of generating high lift and stable flight performance at high angle of attack, the problems related to lack of conventional flow control surfaces compel the researchers to explore new...
Control of flow structure on VFE-2 delta wing with passive bleeding using CFD Sayılır, Serdar Emin; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2018) The utilization of slender delta wings on military platforms like fighter jets and missiles has been a great topic of aerodynamics research for many decades from both experimental and numerical point of view as a result of their superior contributions to the flight performance. Second Vortex Flow Experiment (VFE-2) was carried out by NATO Research and Technology Organization between 2003 and 2008 to judge the realistic capability of the CFD codes which had been developed for simulating the leading edge vort...
Effect of blowing pattern through leading edge on flow structure of 45 degree swept delta wing Günacar, Gökay; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2016) There has been an increasing interest in recent years in control of flow structure over non-slender delta wings, which are the simplified planforms of Unmanned Air Vehicles (UAV), Unmanned Combat Air Vehicles (UCAV), and Micro Air Vehicles (MAV). Different control approaches have been applied to alter the flow structure with particular interests in preventing stall and delaying vortex breakdown. Among different flow control techniques, blowing through leading edge of the wing has been commonly used due to i...
