Abstract:

A three-component balance system for use in measuring drag and lift forces as well as pitching moments acting on a wind tunnel model is presently available in the Department of Aeronautics. The original manual counterweight readout procedure was considered obsolete from the standpoint of data acquisition therefore, a revision was incorporated using strain gage load cells. The design and installation of the electrical readout system is described. Calibration procedures were devised and performed in order to develop a loading output matrix for use with a rapid data acquisition system and compatibility with an analog-digital computer program.
