STAR Program Research Presentations
SOFIA is an infrared observatory mounted on a modified 747 engineered to do infrared astronomy at 45000 feet. The telescope equipment contains a number of sensors and stabilizers that allow the telescope to capture images while mounted in a moving plane. We have developed methods to analyze the performance of the telescope assembly that will help improve the stabilization and image capturing performance of the observatory. Here we present reusable methods to analyze telescope performance data that will enable improvements in the quality of the scientific data that is produced by the SOFIA. This poster focuses on the multi-flight performance …

The Optimization And Packaging Of Materials Safari Science Educational Tool For K-4 Grade Levels, Elizabeth Chandy
Materials Engineering
An interactive materials-based learning kit for K-4 grade levels was refined to effectively be used in outreach and after-school programs. Different safari animals made of different materials are packaged in the kit, along with different activities to explore physical properties. An optimized number and variety of animals and materials were determined. The volume and weight of the Materials Safari learning kit was optimized to meet the user’s needs. One way the product was optimized was reducing the number of animal pieces in the product. Also, two of the testing stations were reduced in size by about fifty percent to fit …

Transient Small Wind Turbine Tower Structural Analysis With Coupled Rotor Dynamic Interaction, George R. Katsanis
Master's Theses
Structural dynamics is at the center of wind turbine tower design - excessive vibrations can be caused by a wide range of environmental and mechanical sources and can lead to reduced component life due to fatigue, noise, and impaired public perception of system integrity. Furthermore, periodic turbulent wind conditions can cause system resonance resulting in significantly increased structural loads. Structural vibration issues may become exacerbated in small wind applications where the analytical and experimental resources for system verification and optimization are scarce. This study combines several structural analysis techniques and packages them into a novel and integrated form that can …
