一种航空发动机叶片冰屑FOD原位疲劳试验机
By designing an in-situ fatigue testing machine for ice chips (FOD) on aero-engine blades, the problem of difficulty in simulating blade damage evolution under high-altitude conditions in existing technologies has been solved. This enables realistic simulation and damage monitoring of blades under complex service conditions, improving the accuracy and stability of the test.

AI Technical Summary
Existing technologies cannot accurately reflect the stress state of aero-engine blades under complex service environments, especially the damage evolution process when subjected to ice debris impacts at high altitudes. Furthermore, existing test equipment is unable to simulate high and low temperature environments, complex gas atmospheres, ice debris FOD, and in-situ damage observation.
An in-situ fatigue testing machine for ice chip FOD on aero-engine blades was designed, comprising a temperature field/atmosphere construction unit, an ice chip FOD simulation unit, a complex load loading unit, a damage monitoring unit, and a drainage unit. It can simulate the impact of ice chips and composite loads on blades under high-altitude conditions and achieve in-situ damage monitoring.
It enables mechanical performance testing of aero-engine blades under near-real service conditions, accurately simulates the damage evolution process under ice chip impact, improves clamping stability and load loading stability, and supports testing under multi-physics coupling conditions.
