Procedure of the updated calculations of disks of aero – engines with removable blades a finite element method in three – dimensional statement in the environment of Femap/Nastran

Problematic. At adaptation of a design discs rotor air gas-turbine drives (GTD) it is necessary to conduct, in particular, strength calculations for what create the computer models corresponding stated designs (delineations) and operation conditions. If creation geometrical part model does not call special difficulties algorithm an finite-element grid carrying out performances disc stress-strain conditions (SSC) with blades can be modified taking into account development programs calculate.
 Research objective. To offer algorithms allowing set exactitude calculate performance SSC on personal computers, also represent outcomes form schedules type "surface".
 Realization technique. On example 2nd stage compressor GTD construction three-dimensional from separate blocks which have been "pasted together" unified has created. Numerical (a contact problem thermoelasticity, isotropic materials) are carried out. For preparation "surface" interface program transformation table columns two-dimensional created.
 The results research. Are created explicitly techniques reaching research objectives described.
 Conclusions. allow carry limited powers exact enough control statement, conduct visualisation distribution stresses forces zone "disc-blades" "surface".
