Abstract
The overall objective of Phase II project is to enhance the capabilities of STARS and similar software to perform fast and accurate analysis of unsteady aerodynamic and aeroservoelastic (ASE) problems. Phase I work demonstrated the feasibility of using system identification to obtain accurate models of unsteady aerodynamics from STARS data and their use in ASE analysis. Phase II work encompasses: (i) reduced order modeling of fluid-structure interaction, (ii) modeling of aerodynamic uncertainties, (iii) bifurcation analysis, (iv) software development, (v) modeling and simulation of aeroelastic and aeroservoelastic problems of aircraft, (vi) modeling of material and geometric nonlinearites as applied to aircraft, and (vii) integration of STARS multidisciplinary software into design environment. The techniques and tools developed in these areas will be applied to a fluid-structure interaction problem such as F/A-18 tail buffet load alleviation problem. SSCI will develop software modules for aerodynamic modeling and ASE analysis. These advanced technology modules will be integrated into STARS software system and thus furthering its multidisciplinary features.
