Aeroelastic Sensitivity Analysis of Airliner Wing by Means of NASTRAN Solver 200
Original language description
This paper describes the airliner wing flutter sensitivity analysis. The sensitivity coefficients defines the influence of the structural parameters changes to the structure eigenvalue and flutter stability characteristics. Evaluated structural parameters represent the possible changes of the structure due to the installation of the smart high-lift devices at the leading and trailing edge region. In general, we can suppose the increasing of the mass and mass moment of inertia around the elastic axis anddecreasing of the stiffness. Described effects are ordinarily considered destabilizing regarding the flutter. The main aim of the presented work is to evaluate the impact of components to the stability and to define the most critical regions or parameters.
