to a six-component balance. The beam is connected to the wind-tunnel structure by
nine motorised pulley systems to control the cables. The location of the model is
determined by hybridisation of the measurements from three gyro meters and seven
accelerometers embedded in the model, and also from the measurements of the
lengths of the nine suspension cables and the processing of images obtained from
two cameras. The determination of the aerodynamic forces exerted on the model
results from a digital processing of all the measurements performed:
