Abstract
The dynamic aeroelastic response of aircraft wings modeled as anisotropic composite thin-walled beams in an incompressible flow and exposed to gust and blast loads is examined. The structural model incorporates a number of nonclassical effects, such as transverse shear, material anisotropy, warping inhibition, and rotatory inertia. The circumferentially asymmetric stiffness layup is used to generate preferred elastic couplings, and in this context, the implication of elastic coupling, warping inhibition on the response is investigated. The unsteady incompressible aerodynamics for arbitrary small motion in the time domain is based on the concept of indicial functions. The implication of directionality property of composite material is revealed, the influence of the gust/blast profiles on the response is discussed, and a number of conclusions are outlined.
