| Abstract: | The basic principle of load enhancement factor is that,which transfere the B basic fatigue life certification test under given load spectrum into the residual strength certification test under given B basic fatigue life of composite airframes.Load enhancement factor can be detered by theoretical of testing methods.The application of load enhancement factors in the certification of composite airframes is also disscussed in this paper. |
