| Abstract: | Flaw tolerance substantiation of helicopter structure is required in FAR/CCAR27/29. 571. The flaw tolerance substantiation approach of full-scale component was shown. The flaw type and parameter, the basic parameters and safe factors of flaw tolerance S-N curve, the load/stress correction of real flaw, the flaw tolerance performance of structure, inspection interval determination were presented in this paper. This offered some references for flaw tolerance substantiation of heli- copter structure. |
