3.1.5 DATA ACQUISITION
For each tested case, the force measurement was carried out over a period of 120 seconds
and the data was acquired at a sampling rate of 1000 samples per second. Thus, the
obtained data records comprised of 120,000 data points, for each data channel. These
data were subsequently used to calculate the mean and the standard deviation, and to
extract the maximum and minimum values of the coefficients of the wind induced drag
and lift forces, and the pitching moment exerted on the tested PVT. Two repetitions of
the measurements were carried out for each test configuration. The obtained
experimental results were used in a comparative analysis described in Chapter 4.
