An Introductory Investigation Of Dust Devils On Mars: Computational Fluid Dynamics Modeling, Alexios Nicolas Philippou, Kakkattukuzhy M. Issac
NASA-Missouri Space Grant Consortium
This report investigates the flow characteristics of tornado like vortices which can be used to describe an array of axisymmetric rotating vertical columns of fluid such as dust devils, steam devils and tornadoes. These vortices have been recreated within vortex chambers in research facilities, but in focus of this report the investigation is conducted through numerical simulations using the Computational Fluid Dynamics (CFD) software package provided by ANSYS. By varying the main governing nondimensional parameter of swirl ratio through the computational domain’s boundary conditions, different flow characteristics appear which confirm theories presented in previous papers. This enables the research conducted …
Analysis Of Laser Cut Living Hinge Pattern Design, Andrew Weber, Hussein Nassar
Analysis Of Laser Cut Living Hinge Pattern Design, Andrew Weber, Hussein Nassar
NASA-Missouri Space Grant Consortium
Living hinges are flexure bearings that consist of one material which makes up both the hinge and rigid end connections. They are typically made of plastics that can naturally bend without causing permanent strain. Plastic living hinges usually consist of a flat, thin strip of material connecting two ends, and have a wide range of commercial applications. The function of these living hinges can be replicated in plywood samples through subtractive manufacturing. Laser cut patterns produced in plywood samples reduce the flexural rigidity of the material and are popular amongst hobbyists.
Exploring New Methods For The Synthetization Of Pdms Based Microgels, Ethan Wandfluh
Exploring New Methods For The Synthetization Of Pdms Based Microgels, Ethan Wandfluh
NASA-Missouri Space Grant Consortium
Microgels are soft granular particles consisting of highly swollen polymeric networks. At relatively low polymer concentrations, these granular particles undergo a jamming-like transition and behave like a soft elastic solid under low applied stresses but will flow like a fluid when the applied stress exceeds the yield strength. This transition from solid-like to fluid-like behavior has led to their application as rheological modifiers for many cosmetic products. Recently, packs of aqueous microgel have been utilized as a sacrificial support bath for embedded 3D-printing of soft materials, including polymers, hydrogels, colloidal particles, and fluid phases. Here, the printing nozzle locally yields …

Servo Mounting Device And Collective Control System Design For The Forward Flight Aero Test Stand, Aaron Jones
Servo Mounting Device And Collective Control System Design For The Forward Flight Aero Test Stand, Aaron Jones
NASA-Missouri Space Grant Consortium
The majority of the ten-week internship was spent designing a servo mounting device, and a collective control system for the Forward Flight Aero Test (FFAT) stand. The servo mounting device uses four threaded standoffs along with a top plate, held together with screws, that raises the servos above the protruding threaded rods and screws. The collective control system is a rectangular block that attaches the swashplate to the servo arms connected to the servo motor. This control rod is used to translate the rotation from the servo arm into collective control for the blade angle. The control rod has two …
Safety Performance Of Different Game-Theoretical Models In An Unsupervised Intersection Crossing Scenario, Brady Bateman
Safety Performance Of Different Game-Theoretical Models In An Unsupervised Intersection Crossing Scenario, Brady Bateman
NASA-Missouri Space Grant Consortium
There are several methods for an autonomous vehicle (AV) to determine its behavior. One area of interest is in using game-theoretical models to determine an AV’s behavior. If AV designers know the relationship between the action taken by players and their corresponding reward functions, then the behaviors of all players can be predicted. This allows for the simulation of player vehicles at an unsupervised intersection. An unsupervised intersection is one where there are no stop signs or traffic lights to help the players make decisions. The motivation of this project is to study the safety and efficiency of three different …
Overdetermined Control Systems On Time Scales, Drew Barnes, Danian Castillo, Nick Wintz
Overdetermined Control Systems On Time Scales, Drew Barnes, Danian Castillo, Nick Wintz
NASA-Missouri Space Grant Consortium
Control theory is a branch of mathematics focused on observing or controlling a process governed by a dynamic equation. We use state-space notation to represent all meaningful information about of our process. This means our processes are expressed in vector form. Typically, the state matrix is square. In this project, we consider a control system where the corresponding state is over-determined, meaning there are more rows than columns. In addition, our state equation is on a time scale T, which allows us to consider discrete, continuous, or hybrid measurements. Here, we offer two methods to solve the dynamic system. Finally, …
Novel Topological Semimetals: Growth & Characterizing Sm3hfbi5, Patrick Lambdin
Novel Topological Semimetals: Growth & Characterizing Sm3hfbi5, Patrick Lambdin
NASA-Missouri Space Grant Consortium
After dozens of reactions, the Missouri State University Crystal Growth Lab created a likely-topological material, Sm3HfBi5, through flux crystal growth methods. First created experimentally in 2015, Weyl materials are desirable and have garnered much interest due to the materials’ ability to conduct electricity exclusively on their surfaces. This paper discusses methods of selecting and mixing materials to be sealed inside an evacuated or argon-backfilled glass tube which itself is placed inside a furnace kept at high temperatures, as part of a flux growth method, as well as discussing results and difficulties encountered while growing the crystals.
Dynamics And Timescales Of Magmatic Processes At Cerro Uturuncu, Bolivia, Sarah Rasor
Dynamics And Timescales Of Magmatic Processes At Cerro Uturuncu, Bolivia, Sarah Rasor
NASA-Missouri Space Grant Consortium
Between 12-25°S latitude there is prolific volcanism fueled by the Altiplano-Puna Magmatic Body (APMB), a mid-crustal magma body above the 30° subduction of the Nazca plate and within 70-80 km thick South American crust. Cerro Uturuncu, the volcano directly above the APMB, demonstrates that the APMB experiences considerable mixing with the surrounding continental crust. Within the past 1 Ma, Uturuncu has experienced six distinct stages of andesitic to dacitic lava. With this research, we contribute greater understanding to the homogenization of and mixing within the APMB and comment on how this relates to magma residence times. The influx and recharge …

NASA-Missouri Space Grant Consortium
The AI Gravity Project uses machine learning techniques to predict the actual value of gravity anomalies in places where data cannot be physically collected due to multiple constraining factors. Artificial intelligence is used to predict these anomalies. The predicted anomalies combined with the physically collected anomalies will eventually be combined to create higher resolution gravity models of the Earth. Here, the details of the first steps of the AI Gravity Project are presented. This includes the data pulling, cleaning, and analyzing the data prior to training the model.

Modeling And Simulation Of An Electrostatic Lunar Particle Sieve, Aaron Berkhoff
NASA-Missouri Space Grant Consortium
The following research was conducted to develop a kinetic particle model, which simulates an electromagnetic sieve used for in-situ material utilization on the lunar surface. A code package was developed to simulate an electromagnetic sieve that uses electrodes to transport fine particles within a cylindrical device. Specifically, this research generates an initial working model for the sieve and tests different electrode configurations. The simulation models different electric fields generated by electrodes, kinetic particle dynamics, and lunar particle distribution. During the case study, which investigates different electrode configurations, it was determined that electrodes oriented such that electrodes located above and below …

Investigating Outcomes Of Inner Planet Formation Influenced By A Jupiter-Like Perturber, Simarpreet Girn
Investigating Outcomes Of Inner Planet Formation Influenced By A Jupiter-Like Perturber, Simarpreet Girn
NASA-Missouri Space Grant Consortium
The most common planets within 1 AU of a star are a few Earth radii in size, dubbed ‘super-Earths.’ Yet the Solar system lacks a super-Earth, and potentially the presence of Jupiter played a role. For this project, the outcomes of in situ inner planet formation under the influence of a massive outer planet were analyzed. Ninety-two N-body dynamical simulations were conducted of the in-situ formation process with a Jupiter-mass planet at a distance of five astronomical units from a host star. These simulations were then compared with the same inner planet conditions without a massive outer planet. The simulations …
