Wing rib and spar design
CFRP is for the spar, GFRP is for the wing skin and balsawood for the ribs. Theoretical design of the wing is carried out by considering the standard values. The geometry of the wing spar and ribs are designed using the CATIA V5 and FE model is done with Altair hypermesh. Spar is the main structural member which carries a bending load.
