Robust design methodologies: application to compressor blades
… shapes due to manufacturing errors, erosion or foreign object damage. In the present study we focus on seeking compressor blade geometries, that are robust in performance in the presence of geometric uncertainty. Sophisticated tools for representing and propagating uncertainty are employed. …

Particle Sensing in Gas Turbine Inlets Using Optical Measurements and Machine Learning
Propulsion systems are exposed to a variety of foreign objects that can significantly damage or impact their performance. These threats can range from severe dangers such as sandstorms and volcanic eruptions, which can induce engine failure in minutes, to condensation and moisture during ground …

Effects of Damage Arrestment Devices on the Fatigue Life of Impacted Composite Sandwich Beams
… of the structure. Further, the effects of foreign object damage on composite sandwich structures are often catastrophic. Damage to the structure is often undetectable through visual inspection, leading to concerns of unknown interlaminar damage through the life of the structure, which can …
