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) ...
Design, analysis, and integration of a turboelectric propulsion and power system for unmanned aircraft
(2020-05)
Electrically powered small unmanned aerial systems face limited range and endurance due to the inherently low energy density of current level of technology batteries. Hybrid gas-electric systems are under development and ...
Turboprop performance and acoustic evaluation for a small unmanned aircraft variable-cycle engine
(2019-05)
Range and endurance of small unmanned aircraft systems (sUAS) driven by gas turbine engines are constrained by high thrust specific fuel consumption (TSFC) resulting from low overall efficiency. This study evaluates the ...
