Abstract 1:

Making AND Breaking: How reliable are some water pipes?

Ashley C. Greene.

Three different types of pipes were tested to see at what point in time they would break. The pipes, PVC pipe, PEX pipe, and CPVC pipe, were filled with water and attached to a helium filled weather balloon. The ends of the pipes were sealed to trap the water inside. The pipes were secured onto a payload in a Styrofoam box surrounded by cheese cloth. This frame secured the pipes and ensured that they stayed in one place and could not move around the container. The …


High Altitude Ballooning And The Effect Of Temperature On Balloon Ascent Rate, Christopher D. Young Nov 2016

High Altitude Ballooning And The Effect Of Temperature On Balloon Ascent Rate, Christopher D. Young

Abstract

High Altitude Ballooning and The Effect of Temperature on Balloon Ascent Rate.

Christopher Young

High-altitude balloons are unmanned balloons, usually filled with helium or hydrogen, that after release, ascend into the stratosphere, generally attaining an altitude of between 60,000 to 100,000 feet. The balloon payload includes scientific experiments on organisms, equipment to study radiation, temperature, ultra- violet radiation, and pressure. The balloon flights and experiments are logged by means of video devices and are tracked from the ground through multiple tracking devices. The effect of temperature on the ascent rate of the balloon could change how the balloon expands …


Model Truss Bridge Design, William Spicer Berry, Kaleb Rankin Dyer, Dustin Lee Schultz Nov 2016

Model Truss Bridge Design, William Spicer Berry, Kaleb Rankin Dyer, Dustin Lee Schultz

Posters-at-the-Capitol

Bridges are one of the most important and costly engineering projects, involving extensive design considerations that try to minimize expenses while insuring the bridge will not fail. Different models of bridges were constructed in order to perform experiments that determined which beams were in compression and how much force was experienced in the beam’s when a static load was applied. Computer simulations were also performed to determine the loads on the different beams. The simulation and calculated results were compared to ensure accuracy of the final results. It was determined that a Howe bridge offers the lowest maximum compression on …


A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender Oct 2016

A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender

ASA Multidisciplinary Research Symposium

This projects presents a bioinspired modification to UAS propellers/rotors for noise reduction. Sound pressure levels (SPL) and thrust for modified propellers were compared to a baseline propeller. The bioinspired modification yielded lower SPL with a requisite increase in rpm in order to maintain a chosen level of thrust.
