Exhaustive testing of complex and autonomous systems is intractable and cost prohibitive; however, design analysis techniques such as formal methods and design methodologies, including run-time assurance, could provide supplementary certification evi

The thermal properties of carbon nanotube- (CNT-) sheet were explored and compared to copper in this study. The CNT-sheet was made from dry spinning CNTs into a nonwoven sheet. This nonwoven CNT-sheet has anisotropic properties in in-plane and out-of

For spacecraft conducting on-orbit operations, changes to the structure of the spacecraft are not uncommon. These planned or unanticipated changes in structural properties tightly couple with the spacecraft’s attitude dynamics and require estimatio

This dissertation explores the benefits of combined control moment gyroscope (CMG) and reaction wheel array (RWA) actuation for agile spacecraft. Agile spacecraft are capable of slewing to multiple targets in minimum time. CMGs provide the largest to

The focus of this investigation is on the formulation and validation of a methodology for the estimation of a stochastic linear modal model of a structure from measurements of a few of its natural frequencies and mode shapes on a few nominally identi

This study explores the feasibility of using a non-contact guided wave imaging system to detect hidden delamination in multi-layer composites. The study is conducted in two phases. In the first phase, Lamb waves are excited by a lead (Pb) Zirconate T

The Rigidizable Inflatable Get-Away-Special EXperiment (RIGEX) was run successfully on board STS-123 (Endeavor) in March 2008. RIGEX was built by graduate students at the Air Force Institute of Technology (AFIT) and returned there following the shutt
