Abstract: A system and method of adaptively managing a plurality of engines in a multi-engine system, where each engine comprises hot gas components and non-hot gas components, and each engine exhibits a performance margin and a remaining useful life, includes continuously, and in real-time, determining a plurality of different degradation mechanisms for each of the plurality of engines, and continuously, and in real-time, determining which of the determined degradation mechanisms is most limiting. The engines are controlled, based on the most limiting degradation mechanism, in a manner that the remaining useful lives of each engine are substantially equal. The plurality of different degradation mechanisms of each engine are determined based on the engine performance margin, modeled failure predictions of the hot gas components, and modeled failure predictions of the non-hot gas components.

Abstract: A method for controlling grain growth in articles of manufacture produced using nano-particle jetting additive manufacturing processes includes the steps of; providing or obtaining nanoparticles of a bulk material, providing or obtaining nanoparticles of a dopant material different from the bulk material, supplying the bulk material and the dopant material to a nano-particle jetting apparatus, and using the nano-particle jetting apparatus, building-up the article of manufacture in a layer-by-layer manner. Each layer includes a mixture of the bulk material particles and the dopant material particles. Furthermore, the method includes sintering the article of manufacture. During sintering, the presence of the dopant material mixed with the bulk material moderates the grain growth of the bulk material.
