The Damage Tolerance Analysis of a Key Component of the Typical Structure of the Advanced Aircraft

The damage tolerance analysis and assessment of the key component of the aircraft under the corresponding load spectrum was given by improved crack growth program.Based on the damage tolerance test results of the key component of the aircraft,the capacity of the damage growth was given exactly and the life of the crack growth and the residual strength were forecasted.The examination of the Full-scale fatigue test was given by the results of the damage tolerance assessment,which ensured the success of the test and achieved good results.
