Probabilistic Modeling of the Aeroelastic Life Cycle for Risk Evaluation of Composite Structures

Virtual aeroelastic tests using Monte Carlo simulations can be used to quantify the aeroelastic reliability of damage-tolerant composite aircraft structures, enabling aircraft manufacturers, operators, and flight certification authorities to establish design, maintenance and service guidelines that reduce lifecycle cost. A probabilistic / reliability methodology and computer simulation capability for composite airframes is presented in this paper and used to study a simple isotropic delta wind tunnel model and a realistic vertical tail / rudder system of a transport airplane.
