Thermal Analysis Of The Temperature Gradient Across Pintle Injector Face, Zoe Brand

Discovery Day - Prescott

Proper analysis of the temperature gradient across the pintle injector face is a complicated surface to acquire a reading from. Complications arise from the extreme temperatures seen on the combustion side mixed with the ambient temperatures seen on the fuel side of the injector. The orientation of temperature sensor placement is critical to mitigate hot spots and not disrupt the thermal flow through the injector face. The installment of the temperature sensors is also a critical issue since a new medium would need to be added to keep the sensor in place. The goal of this research is to figure …

Effects Of Equivalence Ratio During Shutdown Of A Rocket Engine On Hardware Longevity, Benjamin Black

Discovery Day - Prescott

During the shutdown or purge period after firing of a rocket engine it is critical to understand what equivalence ratios are desirable and implement a shutdown sequence so that the hardware is subjected to the lowest thermal and mechanical loading. Furthermore, it is essential that hazards to the test technicians caused by this method be minimized. The initial study was conducted into combustion mechanics, to understand how the reactants would ideally behave at varying equivalence ratios and in both pre-mixed and diffusion flame combustion. Using this foundation an analytical model for a Propane-Oxygen flame was created and tested using a …

Tip Driven Rotor System, Kevin Allyas

Discovery Day - Prescott

The Tip-Driven Rotor System (TDRS) Project is a product designed for KRyanCreative, LLC (KRC), as the basis of a Levitated Annular Rotor System (LARS) for commercial and tactical military vertical takeoff and landing (VTOL) vehicles. Conceptually, this design will greatly increase power density and lift capacity over conventional shaft-centric helicopters. The design also enables variable rotational velocity control that can greatly expand the VTOL flight envelope. The LARS innovatively leverages electromagnetism and superconductive levitation in the transfer of energy from vehicle source to aerodynamic lifting surface. The benefits of LARS include: the reduction of wing tip vortices due to a …

Statistical Shape Model (Ssm) Of Infant Femurs And The Relationship With Severity Of Hip Dysplasia, Tamara Chambers, Penny Atkins, Victor Huayamave, Andrew Anderson, Charles Price

PanaSoMM

The objective is to assess the morphology of infant femurs using a statistical shape model (SSM). The Ortolani collection is used in this study and consists of untreated infant cadaveric specimens with both healthy and dysplastic hips. Computed Tomography (CT) scans of 4 of the 14 specimens in the collection were taken at the University of Padua. Manual and semi-automatic segmentation techniques were used to reconstruct the 2D slices of femurs and generate 3D surface models. The SSM model of the infant femurs will be developed using an open-source software called ShapeWorks developed by the University of Utah. The SSM …

Introducing Modeling to First-Year Engineering Students for Effective Implementation in the Engineering Design Process

Carolina Barriento and Juan Francisco Granizo

Embry-Riddle Aeronautical University

Abstract

Modeling and Simulation are fundamental skills for all engineering students [1]. However, students are usually introduced to these concepts during their junior or even as late as their senior year. Our research aims at familiarizing students with Modeling and Simulation tools in their first year of engineering studies. We consider the fact that proper learning involves using long-term memory (in contrast with working memory) and this is accomplished by the gradual introduction and practice of the …

Solar District Cup Competition, Qi Jiang, Kristen A. Holman, Benjamin F. Aulenbab, Adi Alharbi, Chenge Liu

Sustainability Conference

The Solar District Cup is a two-semester design competition sponsored by the U.S. Dept. of Energy in which teams from across the nation compete to design the most efficient and cost effective solar plus storage system for a unique district case. The Embry Riddle team was tasked with designing such a system for New Mexico State University in Las Cruses, NM.

Solar Powered Parking Lot Lights, Jordyn Taylor

Sustainability Conference

Solar energy is a renewable resource growing exponentially around the country over the past few decades. Solar energy works through the use of photo-voltaic cells, which work to convert energy from sunlight into electricity. This is done within solar panels, which are then connected to batteries for energy storage to use as needed. As production has increased over past decades, the cost for solar panel hardware and installment has thus fallen to meet consumer need. While most common implementations include solar panels attached to one’s home or solar panel ‘fields’ for charging entire towns, there has been a steady rise …

Nasa Human Exploration Rover Challenge, Gabriella E. Fortes, Zach Henney, Mo Sabliny, Johnnie Perry, Jessica Chow, Jessica Turcios, Aaron Taylor, Brenda Haven

Aviation / Aeronautics / Aerospace International Research Conference

NASA's Human Exploration Rover Challenge, held annually in at the Marshall Space Flight Center in Huntsville, Alabama, is an engineering design challenge that asks teams of student engineers to design a human-powered vehicle capable of traversing a simulated lunar surface. The rover must be able to be transported in a 5x5x5 foot cube, echoing the design constraint faced by the engineers who built the Lunar Roving Vehicles used by the astronauts of the later Apollo missions.

Suborbital Spaceflight: A Student Team’S Plan To Send A Rocket To Space, Bryce Chanes, William Carpenter, Julio Benavides, Matthew Haslam, Brenda Haven

Aviation / Aeronautics / Aerospace International Research Conference

The Eagle Space Flight Team was created with the goal of becoming the first undergraduate team to design, build, and launch a rocket capable of suborbital spaceflight. In order to achieve this goal, the team will have to design a rocket capable of atmospheric flight at speeds over Mach 5 and launch it on one of the largest amateur rocket motors ever made. Over the next three years, the team will progress towards accomplishing this feat through a series of incremental test flights. Before the space flight, the team will build three sub-scale rockets designed to reach altitudes of 30,000’, …

Applications Of Long-Wave Thermal Infrared Imagers On Unmanned Aerial Systems For First Responders, Nick Harris, Lorenzo Coykendall

Aviation / Aeronautics / Aerospace International Research Conference

The Embry-Riddle Prescott UAS Team will design, build, and test three Unmanned Aerial Systems (UAS) for competing in the student UAS Competition June 18 - 22 in Patuxent River, MD hosted by the Association for Unmanned Vehicle Systems International (AUVSI).

The team will design and build these unmanned aircraft to carry a five-pound payload, sustain flight for at least forty minutes, and be hand-launchable and rugged; they will be constructed from composite materials and will be fully autonomous through the use of open-source autopilots.
