Title:
Development of Hypersonic Vehicle Design, Modeling, and Optimization Tools
Abstract:
Hypersonic vehicles have been an increasingly rising interest in recent years. With the advent of companies focused on the production of commercial hypersonic aircraft, the need for tools that facilitate and optimize the design and manufacturing phases have increased as well. This presentation showcases the development of two tools: the first determines the minimum flight profile of a hypersonic vehicle given specific thermal protective system (TPS) materials properties and the second is an iterative hypersonic vehicle modeling and optimization framework for analysis in subsonic conditions. Although the underlying science behind them is quite elementary, more complex iterations of the same tools imply a step in the right direction for the emerging hypersonic aviation industry.

Title:
Development and Validation of an Open-Source Propellant Sloshing Simulation
Abstract:
Modern spacecraft must account for the effects of liquid sloshing, defined as the oscillatory motion of fluids within partially filled containers. These effects are especially pronounced where low-gravity vacuum environments exacerbate typical concerns of balance and engine performance. This presentation examines a two-pronged approach of algorithmic development and validation. The first research avenue involves the familiarization with existing modeling techniques, which can then be applied to axisymmetric tanks via a new open-source graphical user interface. Simultaneously, the second path involves the development of a physical test stand that may be used to confirm the analytical results and investigate damping characteristics in unique configurations. The ultimate goal is to combine these tools for use in both the industrial and academic sectors of the New Space Economy.

Title:
Utilizing Model-Based Systems Engineering to Organize and Optimize a Student-Run Organization
Abstract:
Model-Based Systems Engineering (MBSE) is an ever-growing methodology used to better communicate and support system aspects across an entire project lifespan. By creating simple and effective visual models for system requirements, architectures, and activities, critical information can easily be relayed to all members of a project. Utilizing the language of SysML, many software, including Simulink’s MagicDraw, make it easy for system engineers to create said visual models without requiring an understanding of coding languages like SysML. While MBSE is traditionally utilized for physical systems, this research explores its implementation for organizing and optimizing a student organization’s architecture. Survivor Georgia Tech is a relatively-new student-run organization on campus which would greatly benefit from the visual models to enhance member’s understanding of the club’s organization while also optimizing aspects through parameterization techniques and requirements. This project led to the creation of a baseline organization architecture, requirements, and key parameterizations for efficient and effective operations of Survivor Georgia Tech.
