Application of Accelerometers for Measuring Aerodynamic Forces in Short-Term Facilities

Abstract

Methods for restoring aerodynamic forces based on the use of measurement data by balance elements and an accelerometer have been expanded. A signal processing method has been developed that makes it possible to correct the measurement data of balance elements using additional data on the acceleration of support elements. Examples of the application of the proposed method under the conditions of a pulsed wind tunnel in experiments on massive models, both with constant and decreasing flow parameters during the test, are given. An increase in the measurement accuracy of single-component force-measuring sensors is shown.
