AI Technical Summary

Technical Problem

Traditional core engine heating and pressurization test methods only assess discrete typical states, failing to fully verify the performance and structural strength changes of the core engine in the time and process dimensions. This leads to differences between the test results and those under actual flight missions, making it difficult to expose the risk of performance degradation or structural failure.

Method used

The core engine test method based on flight mission profile design improves the accuracy and rationality of the test by determining multiple consecutive typical working stages, calculating the rate of change of inlet conditions, and integrating them into a test procedure that simulates the flight profile of the whole machine.

Benefits of technology

It enables full-process verification of core machine performance and structural strength, improves the authenticity and accuracy of test results, and can better expose potential performance degradation or structural failure risks.
