“…For sting balance, it is possible to assume that the measured forces and moments are linear with respect to the applied forces. The measured forces (N: normal force, and A: axial force) and moments (M: pitching moment) are given by the following equations (Boyle, 1988;Erm & Ferrarotto, 2009).…”

“…The wind tunnel used in this study has as a sting balance (the sensor used to measure forces and moments for models in wind tunnel); hence, it needs to be calibrated. In this work, the sting balance is first calibrated using the described in Boyle (1988), Erm and Ferrarotto (2009) and Ulbrich and Gisler (2013). Then, uncertainty analysis and validation experiments are conducted to evaluate the calibrated wind tunnel data.…”

The increase in the number of Unmanned Aerial Vehicles (UAVs) and Micro Air Vehicles (MAVs), which are used in a variety of applications has led to a surge in low Reynolds number aerodynamics research. Flow around fixedwing MAVs has an unusual behavior due to its low aspect ratio and operates at low Reynolds number, which demanded to upgrade the used wind tunnel for this study. This upgrade enables measuring the small aerodynamics forces and moment of fixed-wing MAVs. The wind tunnel used in this work is upgraded with a state of art data acquisition system to deal with the different sensors signals in the wind tunnel. For accurate measurements, the sting balance, angle sensor, and airspeed sensor are calibrated. For validation purposes, an experiment is made on a low aspect ratio flat plate wing at low Reynolds number, and the measured data are corrected and compared with published results. The procedure presented in this paper for the first time gave a detailed and complete guide for upgrading and calibrating old wind tunnel, all the required corrections to correct the measured data was presented, the turbulence level correction new technique presented in this paper could be used to estimate the flow turbulence effect on the measured data and correct the measured data against published data.

This paper bequeaths particulars of impact of turbulence on the flicker produced in the wind turbine which is sited on that surface. This is achieved in a laboratory wind tunnel with small models of hills with different slopes and wind turbine. Different shapes of models of hills placed in a laboratory wind tunnel. Wind turbines are tested for those conditions. The paper provides an empirical model to find flicker in terms of hill topography. The exquisiteness of the model is that, it is expedient to sundry types hills on which the turbine is sited. Validation of model is carried out with comparative graphs revealed with readings recorded on a turbine in tunnel

Paper presents a newfangled empirical model to figure, flicker, instigated in the horizontal axis, upwind turbine, due to wind turbulence, in continuous operation. Postulations, boundary curbs and limitations of the model are also depicted. In the proposed model, wind turbulence, number of blades, blade length and tower height are echoed. The exquisiteness of the model is that, it is expedient to range of heights of structures on which the turbine is sited. Validation of model is carried out with comparative graphs revealed after vigorous experimentation on a turbine in a tunnel with various heights of models of buildings.Index Terms--flicker emission, wind turbulence, wind turbine.
