This research work covers the design, manufacture and testing of an unmanned aerial vehicle for the purpose of testing various control systems by undergraduate students in the laboratory environment. The aerial vehicle under consideration is a four-rotor propeller powered. Aluminum rod based mechanical structure is preferred. The stabilization of the hovering vehicle in its rotational axes in the air and navigation about the yaw axis are the accomplished goals of this study. The aerial vehicle is run in real time by using Matlab 6.5 Software̕s xPc module. The linear quadratic regulator and PD controllers are utilized to stabilize the aerial vehicle in its rotation axes. To eliminate the measurement noise generated by the sensors, low-pass second order transfer function is designed and its implementation to real time experiments is discussed.

Nanoscale Thermal Transport in Single, Bilayer Graphene, and Graphite Gholivand, Hamed; Donmezer, Nazli (2016-10-12) In this study, ab-initio calculations were performed to obtain phonon dispersions of single, bilayer graphene, and graphite structures. Using these dispersions single mode relaxation times, thermal conductivities, and mean free paths (MFPs) have been calculated. Finally, calculated variables were used to understand the effects of additional layers to thermophysical properties, phonon mode contributions to thermal conductivity, and the limits for ballistic-diffusive heat transfer of single, bilayer graphene,...
Design, construction and performance evaluation of axial flow fans Keklikoğlu, Hayrettin Özgür; Albayrak, Kahraman; Department of Mechanical Engineering (2019) The primary purposes of this study are to examine the methods used in axial flow fan design, to perform these methods on the design of an axial fan, to develop a design application in order to reduce the design errors and spent time in the design process, and to determine the reliability of the application with numerical and experimental methods. This study is concerned with the design of axial flow fans. It provides detailed information about the design process — additionally, a design code is implemented....
Numerical Simulation of a Flexible X-Wing Flapping-Wing Micro Air Vehicle Deng, S.; Perçin, Mustafa; van Oudheusden, B. W.; Bijl, H.; Remes, B.; Xiao, T. (2017-07-01) Numerical simulations were performed to investigate the flowfield around a flexible flapping-wing micro air vehicle using an in-house-developed computational fluid dynamics solver. To include the dynamics of the flexible wings and its impact on the aerodynamic behavior of the micro air vehicle, the wing-deformation pattern during flapping was experimentally determined by a stereovision measurement. These data were subsequently interpolated to be employed as prescribed flapping kinematics in the numerical fl...
Performance improvement of a 3d reconstruction algorithm using single camera images Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005) In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...
Measurement of the elliptic anisotropy of charged particles produced in PbPb collisions at root s(NN)=2.76 TeV Chatrchyan, S.; et. al. (2013-01-01) The anisotropy of the azimuthal distributions of charged particles produced in root s(NN) = 2.76 TeV PbPb collisions is studied with the CMS experiment at the LHC. The elliptic anisotropy parameter, upsilon(2), defined as the second coefficient in a Fourier expansion of the particle invariant yields, is extracted using the event-plane method, two- and four-particle cumulants, and Lee-Yang zeros. The anisotropy is presented as a function of transverse momentum (p(T)), pseudorapidity (eta) over a broad kinema...
