Life Consumption Comparison Between Endurance Test Case and Field Service Case for a Type of Aeroengine
The second HP turbine rotor blade and disk are the key components of a type of aeroengine,for comparing the value of life consumption of the type of aeroengine in endurance test case with field service case,used finite element method to analyze the simulative steady temperature field and stress field of the second HP turbine rotor blade and disk.Based on the fatigue analysis theory of EGD-3 and damage cumulative theory,evaluated the fatigue damage of access points after analyzing the flight parameters and data in endurance test.The endurance damage of blade and disk were achieved by the method of interpolation and Larson-Miller formula.Based on the principle of equivalent damage,compared the damage degree in endurance test case with field service case,the life consumption value in endurance test amount to 1.642 as much as in field service in the same time.
