Conference paper


A six-component strain-gauge balance for short-duration hypersonic facilities is presented. The balance features a new geometry compared to classical strain-gauge balances for model measurements in wind tunnels. The new geometry and the utilization of highly sensitive semiconductor strain-gauges allows for both a short response time, and a high sensitivity. The calibration and data reduction procedures are described in detail. Measurements on a 30° cone at incidence in a M = 7.9 shock tunnel flow are presented. They are compared to inviscid calculations and measurements of other authors, showing that the balance operates reliably.
