The Architecture Selection, Design, And Discharge Modeling Of A Passive Compensation, Iron-Core, Two-Phase, Permanent Magnet Compulsator To Power A Small Railgun Platform, Collin Macgregor
Aerospace Engineering
The goal of this project was to design and build a compensated pulsed alternator, or compulsator, to power the Cal Poly Electromagnetic Railgun Mark 1.1. This project examines the feasibility of implementing mechanical pulsed power supplies for repeatable use with a railgun load for orbital debris hypervelocity testing. The final system architecture chosen was a passively compensated, iron-core, 2-phase, permanent magnet compulsator. The Cal Poly Compulsator will be capable of storing 45 kJ of mechanical energy with a peak operating speed of 5,000 rpm at 190 V. Theoretical calculations resulted in the following predicted electrical performance values: a peak output …

Aerial Deployable Autonomous Solar Powered Glider, Brandon Groshong, Jacob Ohana
Aerospace Engineering
Awareness of green solutions to powered flight is a new trend taking the Aerospace Industry by storm. One particular application that shows high promise is that of photovoltaics on small UAV-type aircraft to help extend flight time. The purpose of this report is to document both research and experimentation performed on a small RC aircraft in order to better understand the electrical requirements of such a device. Using that research, speculation on how it can be used to design a mobile Aerial Deployable Autonomous Solar Powered Glider will be performed. Technologies such as CIGS solar cells and Lithium Polymer batteries …
