Six-component balance calibration technology for nozzle model testing facility

  • The balance calibration technology was developed with the method that theoretical computation was associated with model test in order to improve precision and accuracy of static and dynamic calibrations of six-component force-measuring balance for nozzle internal flow model testing facility.The original data of static calibration were processed by the method in which once quantic was compared to thrice quantic and the experiential model was obtained on phases of balance installation and test.The repeatability test indicates that precision and accuracy of dynamic calibration can be enhanced greatly with perfect method for data processing.The credibility of balance performance and correctness of correcting test data including added-force and added-moment of force-measuring system with the nozzle pressure ratio (NPR) were validated by being compared to the results of dynamic calibration for four-component balance.The method of six-component force-measuring balance calibration offers references for other multi-component force-measuring system calibrations.
