Model-Based Verification and Validation of Component Structures for RF and Optical Experimental Systems

Future large aperture systems will depend on integrated modeling to assess key performance parameters for designs that cannot be fully tested and verified before flight. Achieving this goal will require integrating component models, results from numerical simulations, and physical tests to predict the performance and prove the viability of such systems within numerous model and measurement uncertainties. We will describe the use of JPL´s precision environment test enclosure (PETE) with integrated modeling for radar component and optical metrology experiments to validate models for predictive analysis of large aperture systems. Capabilities of the CIELO software, developed at JPL for integrated structural-thermal-optical modeling, will be presented along with analysis from other traditional tools such as NASTRAN, ANSYS, and FEM tools. We will conclude with the benefits of having the PETE lab for component testing compared to a high-bay environment.
