Design and analysis of Bellwether: A flying wing featuring the bell-shaped spanload
(2021-05)
This body of work details the design and analysis, as well as discussion of requirements for eventual fabrication and flight testing, of a flying-wing aircraft. The design presented is focused primarily on matching the ...
Quantitative analysis of positive-displacement compressor models tested in extrapolation scenarios
(2022-12)
Testing and evaluation of select semi-empirical compressor models is carried out to quantify performance in modulation (variable speed), extrapolation, and additionally, variable superheat scenarios. Three representative ...
Cooperative aerial manipulation with force control and attitude stabilization
(2018-12)
Ranging from autonomous flying cars, fixed wing and rotorcraft UAVs, there has been a tremendous interest in aerial robotics over the last decade. This thesis presents contributions to the state-of-art in cooperative payload ...
Coolant passage segmentation influence on regenerative-cooling effectiveness for small spacecraft thrusters
(2020-05)
The purpose of this thesis is to examine the effect of varying the number of cooling passages in a regeneratively-cooled rocket combustion chamber and nozzle analog for a small spacecraft thruster producing 22N (5lbf) ...
