Comparison of rotor inflow models for flight simulation fidelity
Güner, Feyyaz; Yavrucuk, İlkay; Department of Aerospace Engineering (2016)
In real-time rotorcraft simulations, there are various dynamic inflow models to chose from. Although dynamic inflow models are well documented in literature, a comparisons of them are not commonly available. In this thesis, dynamic inflow models commonly used in flight simulators are, namely uniform inflow, extesion of uniform inflow with Payne’s coefficients, Pitt-Peters inflow and Peters-He inflow model with higher harmonics, integrated to a well-known blade element model. A theoretical background for dyn...

Comparison of transient and quasi-steady aeroelastic analysis of wind turbine blade in steady wind conditions
Sargın, H; Kayran, Altan (2014-6-16)
In the preliminary design stage of wind turbine blade, faster and simpler methods are preferred to predict the aeroelastic response of the blades in order to get an idea about the appropriateness of the blade stiffness. Therefore, in the present study, applicability of the quasi-steady aeroelastic analysis of wind turbine blade is investigated in terms of how accurately the quasi-steady aeroelastic analysis predicts the deformed state of the blade at certain azimuthal positions. For this purpose, compa...
Comparison of parametric models for conceptual duration estimation of building projects
Helvacı, Aziz; Sönmez, Rifat; Department of Civil Engineering (2008)
Estimation of construction durations is a very crucial part of project planning, as several key decisions are based on the estimated durations. In general, construction durations are estimated by using planning and scheduling techniques such as Gannt or bar chart, the Critical Path Method (CPM), and the Program Evaluation and Review Technique (PERT). However, these techniques usually require detailed design information for estimation of activity durations and determination of the sequencing of the activitie...
Comparison of axial flux and radial flux brushless dc motor topologies for control moment gyroscope wheel applications
Yılmaz, Kurtuluş; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2009)
In this thesis axial flux and radial flux brushless dc motors will be studied as a drive motor for the control of moment gyroscope wheel. Design equations for axial flux and radial flux brushless dc motor topologies will be reviewed. Based on these equations radial and axial flux motors with different number of poles will be designed that meet control moment gyroscope wheel application requirements. The results will be evaluated in terms of efficiency, torque/mass and torque/volume, and suitability for the ...
