And yQ3The die-away time when service life is renovated using this time；
Actual life formula in the step 55 is：
M=m'+m "+m " ' ...；Wherein,
M', m ", m " ' ... number when being the use after overhauling each time.
2. the method for calculating engine main chamber burner inner liner actual life as described in claim 1, which is characterized in that
First loading spectrum is different loading spectrums from second loading spectrum；T in the step 1 is 2000h, the step 2
In T '=500h, t '=750h in the step 4.
