The stress-strain state features of the helicopter blade butt

,

Abstract:

There are analysis results of stress-strain state of the helicopter composite blade butt in this article. Rig tests for determination of crushing load are performed and characteristic features of blade butt crush are detected. Finite element model with nonlinear boundary conditions on the contact surfaces of the construction are building. On the ground of made calculations the conclusions about crush probable scripts of the blade butt part are formulated.
