(Massachusetts Institute of Technology, 2016)
Biomechanics of extravehicular activity and its neutral buoyancy simulation
(Massachusetts Institute of Technology, 1987)
Tradespace analysis for Earth Observation Constellations : a value driven approach
(Massachusetts Institute of Technology, 2020)
In recent years, the Earth Observation (EO) industry has experienced rapid growth and development, but the tools to analyze EO constellations and space systems are lagging behind the curve. In particular, as costs continue ...
1D scramjet model
(Massachusetts Institute of Technology, 2020)
Renewed interest in hypersonic research has motivated a number of scientists to reinvestigate the efficacy and performance of supersonic combustion ramjets, colloquially known as "scramjets". In this thesis, a 1-D scramjet ...
Formulation and evaluation of parallel algorithms for the orbit determination problem
(Massachusetts Institute of Technology, 1980)
Performance scaling of a novel Modular Hybrid Propulsion System for aircraft flight performance flexibility and enhancement

A novel propulsion system concept, the Modular Hybrid Propulsion System (MHPS) is introduced that has the potential to enable a step-change in aircraft performance and flexibility over traditional carbon-fuel propulsion ...
Stability analysis of electromagnetically supported large space structures
(Massachusetts Institute of Technology, 2016)
The high cost per unit mass of launch and the fixed envelope of a launch vehicle fairing respectively incentivize the reduction of spacecraft mass and stowed volume, while the performance boosts that come from an increase ...
Electrochemistry of room temperature ionic Liquids with applications to electrospray propulsion
(Massachusetts Institute of Technology, 2016)
Room Temperature Ionic Liquids (RTILs) exhibit a number of physical properties that have opened new doors for technological advancements in space-based micropropulsion, focused ion beam, energy storage, and other research ...
A systems-engineering assessment of multiple CubeSat build approaches
(Massachusetts Institute of Technology, 2016)
This research conducts a broad systems-based analysis of CubeSat engineering, with a focus on testing, failures, and their relationship to program cost, in order to assess multiple build approaches with a goal of maintaining ...
Numerical models of Hall thruster ionization oscillations
(Massachusetts Institute of Technology, 2016)
In this thesis, low frequency ionization oscillations in Hall thrusters resembling the breathing mode are studied through computational simulation. The relationship between wall erosion and discharge current oscillations ...
