| Abstract: | The dangerous analysis has been done on the structure damage at No. 1 rib bulkhead butt-joint area of L-11 trainer wing by adopting the structure damage analysis computation program based on the equivalent crack extension method. The results have shown that the butt-joint structure area can meet the design life index of L11 jet trainer. |
