Abstract

Abstract:

The design conception of damageable substitute is for the first time applied to control the fatigue life of a wing with beams and it is also verified in the fatigue life tests of main beams of wings and aircraft components. The results are very satisfactory and thus an extremely successful access is supplied to achieve the aims of long life and high reliability of wing structures with beams.

Key words: wing with beams, damageable substitute, control life, fatigue crack

CLC Number:

V215.5
