Technical Abstract

The goal of the project is to develop an intelligent framework to construct adaptive parametric reduced order model (PROM) database for aeroservoelastic (ASE) analysis and aerostructural control. Leveraging on significant advancements by the proposing team in prior research, this Phase I effort will initiate a new frontier of ‘engineering intelligence’ to further ASE ROM development, including several emerging techniques: genetic algorithm optimization-guided ROMs, data-driven ROM for nonlinear aeroelasticity and gust response analysis, online determination of critical flight conditions and in-situ PROM database development while modeling, CFD computation, and ROM are in progress. A modular software framework will be established for automated PROM generation and optimization, consistent state enforcement, adaptive parameter space sampling, and database population. The feasibility of the proposed technology will be demonstrated for ASE problems of NASA interest (e.g., High-speed ASE, X-56A MUTT, etc.). The Phase II effort will focus on: (1) PROM engine optimization in terms of execution efficiency, robustness, and autonomy; and (2) direct integration of the ‘intelligent’ environment into NASA workflow; and process automation of modeling, simulation, and control synthesis for technology insertion and transition; and (3) extensive software validation and demonstration for ASE and flight control analysis of realistic aircrafts of current NASA interest

Potential NASA Applications

The developed technology will enable NASA to (1) determine critical flight conditions and guide CFD/ASE computation and flight testing; (2) enable real-time ASE simulation and flight control synthesis, and (3) develop advanced aerostructural control strategies. It will markedly reduce development costs and cycles of aerospace vehicles. NASA projects like High Speed ASE, MUTT, and MADCAT will benefit from the technology.

Potential Non-NASA Applications

The non-NASA applications are vast, and will focus on aerospace, aircraft, and watercraft engineering for fluid-structural interaction and fatigue analysis, real-time flow control and optimization, hardware-in-loop simulation, and others. The proposed development would provide a powerful tool to generate fast ROMs, which can be used for (1) fault diagnostics and optimized design; (2) design and planning of simulations and experiments, and (2) development of advanced control strategies.
