Device for Measuring Aerodynamic Forces,
Abstract
This invention is in the field of aerodynamic tests, and it is intended for use in wind tunnels for short-term action. We know about devices for measuring aerodynamic forces which contain scales outside the models with force transducers and an accelerometer fastened to a holder or onto the housing of the scales. The signals from the transducers are added and supplied to a meter. The problem with these devices is that they do not adequately compensate the signals for the oscillations of the holder and the vibrations of the scale housing. The purpose of this invention is to eliminate this drawback. This is done by simultaneously introducing a correction for the linear and angular accelerations of the model measured with an accelerometer installed in the holder at the model attachment site.
