Abstract
Aeroservoelastic (ASE) modeling and vehicle stability analysis are twomajor concerns in the accurate prediction of flight characteristics ofgeneric hypersonic vehicles (GHVs). We propose to develop an ASE modelingand vehicle stability analysis toolkit. System Identification (SI)-basedblack box models of CFD solvers is the primary focus in Phase I.Bifurcation and Chaos Theory Methodology (BACTM) is the main tool fornonlinear stability analysis. The proposed software consists of a libraryof ASE model structures, SI routines, and BACTM modules. The software willenhance the capabilities of STARS code currently in use at NASA Dryden.Phase I work involves: (1) acquisition of GHV models, STARS training dataand code, (2) development of ASE modeling toolkit for GHV, (3) nonlinearanalysis of ASE, (4) trajectory optimization and GHV flight stabilityanalysis, (5) integration of software modules into STARS, and (6) finalreport and software delivery. Specific problems addressed include nonlinearflutter analysis, effect of modeling uncertainties, nonlinear flightdynamics in the presence of inertia coupling and unsteady effects. Prof.Lutze of VPI and Prof. Klein of JIAFS/GWU will serve as subcontractors inthis project. ~000063 ~
