Abstract

This paper provides information on the calibration matrix of the aerodynamic six-component external balance of the TA-2 wind tunnel. The balance allows different sets of load cell arrangements. Least squares method is used to fit the parameters of the calibration mathematical modelling. Data from eight campaigns were analysed considering the dimension of the matrix elements equal to one. Parameters and associated uncertainties which represent the behaviour of the balance over time were obtained.
