AI Technical Summary

Technical Problem

In the prior art, blade impact testing, high temperature environment simulation and humidity simulation are all separate experiments that cannot be integrated together, and the launch angle of the bird bomb cannot be changed, which cannot simulate the various environmental and angle impact conditions that the blades may face during actual aircraft operation.

Method used

An engine test device is designed, including a test chamber, a heater, a water tank, a nozzle, a workbench and a telescopic device. The high temperature environment is simulated by the heater, the water pump and the nozzle simulate the humidity environment, and the test of impacting the blades from different angles is realized through adjustable guide rails and electric slides.

Benefits of technology

The real environment simulation of the blades at different temperatures and humidity is realized, and the impact test can be carried out from different angles, enhancing the authenticity and applicability of the test.
