Conclusions

  1. 1.

    New alloys 1161, 1163, and 1973 are markedly better in crack resistance than alloys D16ch and V95pch respectively, which makes it possible, apart from increasing resource characteristics, to increase the level of design stresses and consequently the weight efficiency of aircraft.

  2. 2.

    Use of pressed panels instead of rolled plates makes it possible to realize in structures according to residual strength conditions higher levels for design stresses.
