Production tests on test-benches are mandatory before aircraft engines are delivered, as the measurements taken during the tests determine whether the engine meets the requirements. They are essential for both the aircraft and engine manufacturer. The latter can get a comprehensive picture of the performance of each engine. Such tests involve numerous measurements, the analysis of which is a challenging task.
The study presented in this article aims to detect possible biases introduced by the instruments used to measure the engines, especially the test-bench itself, during the tests. We propose a method to correct these biases. At the end, it will be necessary to verify that the data are corrected, ie that the measurements no longer depend on the test-bench on which they were made. This analysis is the follow-up to previous work on thrust tendency estimation.
