| description | This paper provides a study on passive aeroelastic control optimization, by means of
aeroelastic tailoring, of a composite supersonic wing equipped with external stores. The
objective of the optimization is to minimize wing weight by considering the aeroelastic flutter
and divergence instability speeds as constraints at several flight altitudes. The optimization
variables are the composite ply angle and skin thickness of the wing box, wing rib and its
control surfaces. The aeroelastic instability speed is set as constraint such that it should be
higher than the flutter speed of a metallic base line model of supersonic wing having
previously published. A finite element analysis is applied to determine the stiffness and mass
matric of the wing and its multi stores. The boundary element method in the form of doublet
lattice method is used to model the unsteady aerodynamic load. The results indicate that, for
the present wing configuration, the high modulus Graphite/Epoxy composite provides a desired
higher flutter speed and lower wing weight compare to that of Kevlar/Epoxy composite as well
as the base line metallic wing materials. The aeroelastic boundary thus can be enlarged to
higher speed zone and in the same time reduce the structural weight which is important for a
further optimization process. |
