Real time monitoring and forecasting of full scale aircraft static test

Abstract To meet the airworthiness certification requirement of the full scale static test for ARJ21-700 commercial aircraft, a real time monitoring and forecasting software is presented. The software contains a database which stores all the material data, finite element analysis (FEA) model and results, strain gages and displacement transducers' information, etc. The software can also compare the test data with the FEA and theoretical results, and forecast the next and the final test results based on the analytical and test data in real time. With the support of this software, aircraft designers can monitor the strain and displacement data through distributed monitors and calculate the structure stress and safety margin in real time and can prevent unexpected accidents. Now this software has already been successfully used in the static test of ARJ21 with its high accuracy and reliability.
