Abstract
This paper describes an analysis of the static aeroelastic response of an aircraft with asymmetrical wing planforms representing combat damage using the MSCINASTRAN Aeroelastic Code. Wings(with ailerons), stabilators, and vertical wings(with rudders) are considered as lifting and control surfaces in the aerodynamic model. Structural and aerodynamic analyses are based on the finite element approach and are created independently for both the damaged and undamaged cases. Five different wing structural models, one undamaged and four damaged, are examined in this paper. Doublet-Lattice subsonic theory is used to account for interference effects among multiple lifting surfaces and bodies. The stability and control derivatives, airloads, and trim values are obtained for the damaged-wing aircraft. Effects of the static aeroelastic analysis of the damaged wing on the aircraft's maneuvering flight are discussed.
