It is a problem to achieve an acceptable confidence level in the determination of the aero dynamic coefficients in short duration facilities. Measurements of non-stationary aerodynamic load in this sort of wind tunnels require the application of special designed high-rigidity sting-mounted strain gauge balances. Natural mass of the model causes to develop special methods, which can remove the dynamic errors due to inertial forces from the balance data. Some of possible compensation techniques are described. It was the purpose of present study to investigate the possibilities of non-stationary aerodynamic load measurements when the mass of the model is small and dynamic errors are negligible.
