Control of Flow Structure over a Nonslender Delta Wing Using Periodic Blowing
Cetin, Cenk; Celik, Alper; Yavuz, Mehmet Metin (2018-01-01)
The effect of unsteady blowing through the leading edge on the flow structure over a 45 deg swept delta wing in relation to the steady blowing is experimentally studied in a low-speed wind tunnel using the techniques of surface-pressure measurements, particle image velocimetry, and laser-illuminated smoke visualization. The unsteady blowing in the form of a periodic square pattern at 25% duty cycle is provided at the excitation frequencies varying from 2 to 24 Hz for a fixed momentum coefficient. The flow s...
Control of flow structure on 45 degree swept delta wing using passive bleeding
Karagöz, Burcu; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2017)
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 s...
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...
Control of underactuated planar pronking through an embedded spring-mass Hopper template
Ankaralı, Mustafa Mert; Saranlı, Uluç (Springer Science and Business Media LLC, 2011-02-01)
Autonomous use of legged robots in unstructured, outdoor settings requires dynamically dexterous behaviors to achieve sufficient speed and agility without overly complex and fragile mechanics and actuation. Among such behaviors is the relatively under-studied pronking (aka. stotting), a dynamic gait in which all legs are used in synchrony, usually resulting in relatively slow speeds but long flight phases and large jumping heights. Instantiations of this gait for robotic systems have been mostly limited to ...
Control of flow structure on low swept delta wing using unsteady leading edge blowing
Çetin, Cenk; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2016)
There is an increasing interest in recent years in the aerodynamics of low swept delta wings, which can be originated from simplified planforms of Unmanned Air Vehicles (UAV), Unmanned Combat Air Vehicles (UCAV) and Micro Air Vehicles (MAV). In order to determine and to extend the operational boundaries of these vehicles with particular interest in delaying stall, complex flow structure of low swept wings and its control needs to be understood. Among different flow control strategies, blowing through differ...
