Understanding And Minimizing The Effects Of Propellant Mean Bulk Temperature Changes In Solid Rocket Motors, Thomas Sorensen Apr 2023

Understanding And Minimizing The Effects Of Propellant Mean Bulk Temperature Changes In Solid Rocket Motors, Thomas Sorensen

Student Research Symposium

Solid rocket propellant typically contains the geometry of an extruded annulus. This propellant, when ignited, burns radially at a rate called the “burn rate”. This rate dramatically affects important motor performance characteristics such as pressure, thrust, and specific impulse. Each different mixture of solid rocket propellant has a sensitivity to initial propellant temperature. The relationship between burn rate and initial temperature sensitivity function are each determined experimentally. This literature review will analyze existing experimental data. The objective of the research is to see if there is a reliable way to predict the burning rate’s temperature sensitivity prior to obtaining new …

Controlling Oxidizer-Fuel Ratio With Vortex Injection In Hybrid Rockets, Max Francom Apr 2023

Controlling Oxidizer-Fuel Ratio With Vortex Injection In Hybrid Rockets, Max Francom

Student Research Symposium

Hybrid motors have existed as a hypothetical propulsion system for decades in a wide range of upper stage rocket motors due to their simple, robust, non-toxic, and versatile nature. However, inherent to hybrids is oxidizer:Fuel ratio (O:F Ratio) shift over time, the elimination of which would remove many potential barriers to hybrid rocket motor usage in most spaceflight applications. The most important and difficult part of analytical models of hybrid rockets is the regression/combustion rate of hybrid fuel. O:F Ratio control is fully dependent on the ability to manipulate this regression independently of Oxidizer mass input. One potential method of …

In-Situ Optical Measurements Of Combustion Plumes, Cara Frischkorn Apr 2023

In-Situ Optical Measurements Of Combustion Plumes, Cara Frischkorn

Student Research Symposium

The exhaust plumes of rocket and jet propulsion systems feature highly-oxidizing, potentially corrosive, extremely high temperature flows. The hostility of these environments makes obtaining in-situ thermal flow measurements extremely difficult. The conventional method for these measurements uses Gardon heat-flux gauges requiring complex and highly invasive installations which cannot be used for flight applications. More recent work has used fiberoptic cable installations to sense internal flow conditions of hybrid and solid fuel rockets. In this configuration, fiber optic cables inserted through the fuel and into the flow are consumed by the flame as the fuel surfaces pyrolyze, but the cable tips …

A New Framework To Assess The Individual Fairness Of Probabilistic Classifiers, Muhammad Fawad Akbar Khan Apr 2023

A New Framework To Assess The Individual Fairness Of Probabilistic Classifiers, Muhammad Fawad Akbar Khan

Student Research Symposium

Fairness in machine learning has become a global concern due to the predominance of ML in automated decision-making systems. In comparison to group fairness, individual fairness, which aspires that similar individuals should be treated similarly, has received limited attention due to some challenges. One major challenge is the availability of a proper metric to evaluate individual fairness, especially for probabilistic classifiers. In this study, we propose a framework PCIndFair to assess the individual fairness of probabilistic classifiers. Unlike current individual fairness measures, our framework considers probability distribution rather than the final classification outcome, which is suitable for capturing the dynamic …

Relating Throttled Hybrid Motor Performance To Oxidizer-To-Fuel Ratio, Trevor Coombs Apr 2023

Relating Throttled Hybrid Motor Performance To Oxidizer-To-Fuel Ratio, Trevor Coombs

Student Research Symposium

A hybrid rocket motor's ability to throttle and restart, along with other desirable traits, drives its potential to be an emerging technology in spaceflight applications. However, the current lack of an ability to maintain an optimal mixture ratio of oxidizer to fuel propellants, O/F ratio, during combustion limits the hybrid motor's overall efficiency. This study quantifies how variations in O/F ratio and combustion chamber pressure, which a throttle valve can indirectly manipulate upstream of the chamber, affect the characteristic velocity (c * ) and specific impulse (Isp) of the motor. The researcher uses an analytical hybrid rocket combustion model and …
