Undergraduate Student Researcher for Space Mission Trajectory Analysis
-
Jun 2017 - Sep 2018
-Worked on the proposed Nuclear Thermal Propulsion Project called the Jesse Owens Spacecraft. A Joint Project between NASA Marshall Spaceflight Center, BWX Technologies Inc., and the Ohio State University with a goal to develop the capability of Nuclear Thermal Propulsion to decrease travel time for future deep space missions - Programmed MATLAB code that performed orbital mechanics calculations to optimize around time, thrust, energy and reliability in delivering a spacecraft to the outer solar system in a timespan of approximately 6 months after launch. -Created tripled nested for loop that optimized possible trajectories using a range of Isp and thrust requirements using Hohman Transfers and Tsiolkovsky Equations. Filtered 34 datasets from 4900 possible combinations that satisfied conditions. -Co-author on a paper titled "Analysis of Nuclear Thermal Propulsion (NTP) enabled heliopause trajectories, using Solar-Oberth Maneuvers and inner planetary gravity assist" that was presented in the IAC 2018 Conference in Bremen, Germany. -Focus of this paper was comparing sets of Oberth maneuvers by flying an interplanetary trajectory as close to the sun as possible and firing the engine at Perihelion to escape the solar system as fast as possible.
