  • For a certain aero-engine, strain gauges layout and bridges design on the main load-bearing components of areo-engine installation structure were carried out. To establish the relationship equations between strain output and load input, load calibration tests were conducted on the installation structure components and the whole structure respectively. And the correlation and significance for calibration equation of the thrust was analyzed in this approach. The results of correlation coefficient and F-measure reached more than 0.999 and 22000 respectively. Comparing the thrust calculations and load values, the errors under one-direction and two-direction were less than 2%. Results show that calibration equation has high accuracy. With introduction of the flight data into calibration equations, the engine thrust-time history curve was obtained. By contrast, the developmental trends of engine thrust-time history curves and engine fuel flow-time history curves coincided well. The results verify effectiveness and feasibility of the engine thrust test method further, and provide an enforceable technical approach for engine thrust measurement in actual flight.
