Abstract
The demonstration micro turbopump was designed to prove the feasibility of pumping a liquid using a turbopump on the micro scale. This thesis presents the first data indicating positive pumping from the demonstration micro turbopump. Data pertaining to both the turbomachinery as well as the bearing systems for these preliminary tests is shown and discussed. The pressure rise through the pump, turbine pressure ratio, respective powers, and a system efficiency are presented. Bearing theory and static flow test data are discussed. The pump design is detailed. Modelling data is presented to help describe the operational difficulties with the highly coupled aft bearing system. These operational difficulties lead to the redesign of the aft bearing system, which is described in detail. Other operational procedures developed and discussed include the pump start up procedure and the use of the inverted journal bearing.
