Abstract

The measurement function of wind tunnel balances is to separate vectorially the force vector K into the three X-Y-Z coordinate force directions or moments. The state of the art for external balances is strain-gage platform balances with computer separation of forces and moments. On the basis of experience gained with such balances, a new type of balance has been developed which combines the advantages of computer separation with the advantages of both platform- and pyramidal-type balances. This allows for a significant reduction of the load cells required for calibration of different heights within the test section and for considerable improvement of measurement accuracy of roll, pitch, and yaw moments
