Abstract

The overall goal of the project is to develop reliable reduced order modeling technologies to automatically generate nonlinear, parameter-varying (PV), aeroservoelastic (ASE) reduced-order models (ROMs) for aerostructural sensing and control. The Phase I effort will focus on developing several key engines, including parameter-varying aerodynamic ROMs (AeroROM), structural dynamics ROM, as well as a scheme to integrate the AeroROM, structural ROM, sensor, actuator, and control law for integrated ASE analysis in the entire flight envelope. A modular software framework will be established for automated data exchange, PV AeroROM and structural ROM generation, ROM integration, computation, and verification. The feasibility of the proposed technology will be demonstrated for several ASE test problems of NASA interest (e.g., Aerostructures Test Wing and X-56A MUTT). The Phase II effort will focus on: (1) ROM engine optimization in terms of functionality, execution efficiency, and automated parameter selection; and (2) software environment enhancements with direct interfacing to NASA-relevant simulation and controller design tools, and fully automated ROM process 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.
