Design and Experimental Investigation of a Wind Tunnel Gust Generator

This work aims at developing a two-vane gust generator for a small size open-loop wind tunnel to study the unsteady aerodynamic response of lift producing test models. The focus of the study is two-fold: (1) the design of a gust generator which produces the desired gust profiles by varying the parameters such as flow speed, pitching frequency of the vanes, maximum angle of deflection of the vanes and spacing between the vanes and (2) the experimental investigation of the gust velocity profiles via particle image velocimetry (PIV). Preliminary results of the numerical simulations reveal that a sinusoidally pitching vane design with NACA0015 profile is capable of generating a gust ratio of 0.15. The outcomes of this study will serve as a starting point for the design of a gust generator which will be placed in the Large Scale Wind Tunnel of METU Center for Wind Energy Research (RUZGEM).

Experimental investigation of the effects of tip-injection on the aerodynamic loads and wake characteristics of a model horizontal axis wind turbine rotor
Abdulrahim, Anas; Uzol, Oğuz; Department of Aerospace Engineering (2014)
In this study, tip injection is implemented on a model Horizontal Axis Wind Turbine (HAWT) rotor to investigate the power and thrust coefficient variations as well as the wake characteristics. The model wind turbine has a 0.95 m diameter 3-bladed rotor with non-linearly twisted and tapered blades that has NREL S826 profile. The nacelle, hub and the blades are specifically designed to allow pressurized air to pass through and get injected from the tips while the rotor is rotating. The experiments are perform...
Genetic Algorithm based aerodynamic shape optimization tool for wind turbine blades and its implementation to helicopter blades
Polat, Özge; Sezer-uzol, Nilay; Tuncer, İsmail Hakkı (2014-01-01)
This study presents a methodology first built up for the aerodynamic shape optimization for wind turbine rotors and its modified version for a helicopter rotor in hover. The Genetic Algorithm (GA) coupled with an in-house Blade Element Momentum (BEM) tool is used in the design optimization process. The wind turbine blade optimization studies are performed for maximizing the power production at a given wind speed, rotor speed and rotor diameter, while for the helicopter blade optimization in hover, figure of...
Modeling and experimental identification of quadrotor aerodynamics
Kaya, D. Derya; Kutay, Ali Türker; Department of Aerospace Engineering (2014)
The aim of this study is to obtain mathematical models for aerodynamic forces and moments of rotors of a quadrotor helicopter, and estimate their parameters through wind tunnel tests for hover, vertical climb, and forward flight conditions. The main factors which determine the movement of a quadrotor UAV are the aerodynamic forces and moments in three axes created by four rotors of the vehicle. Hence, accurate calculation of rotor forces and moments in varying flight conditions are essential to establish a ...

This study aims to optimize the impeller geometry of a backward-curved blade centrifugal fan in a helicopter oil cooler to improve the aerodynamic performance of the impeller. The study consists of three main parts: aerodynamic design and parametrization of the impeller, numerical analysis of impeller performance, and multi-objective design optimization to maximize fan static pressure and total to static isentropic efficiency. In the first part, a one-dimensional impeller design is performed using quasi-exp...
Design and Experimental Investigation of a Wind Tunnel Gust Generator
Yığılı, İmge; Perçin, Mustafa; Department of Aerospace Engineering (2022-9-01)
In the design, certification and operation cycles of air vehicles, wind turbines, etc., it is critically important to quantitatively demonstrate the capability of the vehicle to withstand any environmental and meteorological condition. Of several atmospheric conditions, one very common and significant one is the atmospheric gust. Therefore, capacity to generate gust in a fully controlled manner is of utmost importance. In wind tunnels, gust generation is done by means of gust generators, which are devices p...
