Bird skeleton bionic force bearing structure and design method thereof

The invention relates to the field of aero-engine stator component force-bearing structures, and discloses a bird skeleton bionic force-bearing structure and a design method thereof.The force-bearing structure is a rotation structure with the center line of an aero-engine as a rotation axis, the rotation section of the force-bearing structure comprises a force-bearing skeleton, a pre-rotation nozzle and a herringbone ring assembly, and the force-bearing skeleton is a force-bearing vertebra skeleton bionic body; the pre-swirl nozzle is a bionic bird skull, and the herringbone ring assembly is a bionic posterior limb skeleton. The rotation section of the load-bearing structure is formed by fitting a bird bionic load-bearing framework curve, and the load-bearing framework is designed into a variable-thickness load-bearing framework according to load-bearing load distribution, so that the load-bearing structure is good in integrity and reasonable in mechanical distribution, and the equivalent stiffness/strength i
