Systematic multiparameter design methodology for an ultrasonic health monitoring system for full-scale composite aircraft primary structures

The successful utilization of guided wave-based structural health monitoring (SHM) for detailed quantitative diagnostic of damage in composite aircraft primary structures depends on the excitation frequency, geometry, and positioning of the piezoelectric transducers. This study proposes a novel methodology to consistently define those parameters...

Aeroelastic tailoring of flexible composite aircraft

This paper presents a unified framework for aeroelastic tailoring of fully-flexible free-flying composite aircraft. A continuous-time state-space model is used to describe the flow. The 3D composite wing structure is condensed into a Timoshenko beam model utiliz-ing a cross-sectional modeler. The aerodynamic and structural models are tightly...

Multi-level repair decision-making process for composite structures

This paper details the development of a decision-making model that evaluates the multiple repair levels that a composite structure can undergo, each with its inherent achievable survivability and consequence to operations in terms of availability, costs, and scheduling. The goal of this model is to provide the maintainer an integrated approach...
