Abstract:
The paper presents a method of recovery of gas flow pressure from the results of measurements by a piezoelectric pressure sensor in short-duration wind tunnels. It is assumed that the measuring system is a linear dynamic object. A quasisolution of linear Volterra integral equation of the first kind is constructed based on the condition that the equation holds on average in successive intervals into which the time interval of the measurement is divided. An experimental technique for determining the normal response of the sensor (transfer function) is proposed, and an example of recovery of air flow pressure in a wind tunnel is given.
Keywords:
short-duration wind tunnel, pressure, Volterra integral equations of the first kind.
