The article presents the results of

design optimization

of the

pylon

support

beam for me-

dium-haul aircraft

aimed at reducing dead weight, as well as improve the efficiency of

this beam. Designing of a new execution of support beam is based on the strength finite

element analysis in MSC.Software PATRAN/NASTRAN. To assess the degree of compli-

ance with the new design requirements set we carried out calculations of rigidity and the

natural frequencies of the beam.

Keywords:

pylon support beam, finite element, strength, rigidity
