Fiber optic gyroscopes (FOGs) are common rotation measurement devices in aerospace applications. They have a wide range of diversity in length and winding radius of coils to meet the system requirements. Every dimensional parameter in the coil influences the dynamic response of the system, which eventually leads to measurement errors. In order to eliminate the errors and qualify the system, after the design and production stages, a deep and comprehensive testing procedure follows. In this study, the dynamic...
Dynamical Modeling of the Unsteady Flow over a Flapping Wing by applying Proper Orthogonal Decomposition and System Identification to Particle Image Velocimetry Data
Durmaz, Oguz; Karaca, H. Deniz; Ozen, G. Deniz; KASNAKOĞLU, Coşku; Kurtuluş, Dilek Funda (2011-12-15)
In this work a novel approach for the dynamical modeling of the unsteady flow over a pitching airfoil is considered. The technique is based on collecting instantaneous velocity field data of the flow using particle image velocimetry (PIV), applying image processing to these snapshots to locate the airfoil, filling the airfoil and its surface with proper velocity data, applying proper orthogonal decomposition (POD) to these post-processed images to compute the POD modes and time coefficients, and finally fit...

In this study dynamic mesh forces and dynamic factors in a geared shaft system are studied by using a continuous system model. The system consists of a gear pair, two shafts carrying gears, and two inertias representing drive and load in the system. A continuous system model is used to include the shaft inertias, which are usually disregarded even in most of the sophisticated models. The primary aim of this work is to provide a tool for studying the effect of shaft inertia in gear dynamics, and to present s...
Dynamical modelling of the flow over a flapping wing using proper orthogonal decomposition and system identification techniques
DURMAZ, Oğuz; KARACA, H Deniz; ÖZEN, G Deniz; KASNAKOĞLU, COŞKU; Kurtuluş, Dilek Funda (2013-04-01)
A systematic approach for the dynamical modelling of the unsteady flow over a flapping wing is developed, which is based on instantaneous velocity field data of the flow collected using particle image velocimetry (PIV) and computational fluid dynamics (CFD) simulations. The location and orientation of the airfoil is obtained by image processing and the airfoil is filled with proper velocity data. Proper orthogonal decomposition (POD) is applied to these post-processed images to compute POD modes and time co...
