Keywords: wind tunnel balance, strain gauges
A very stiff six-component wind tunnel balance of simple construction
was produced with semiconductor strain gauges on the axial-load element
and with a temperature sensor installed. Thermocompensation was performed
by software, treating the temperature sensor as the seventh balance load
component. Calibration of the prototype validated the concept.
