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
