Profile: I am a very detail oriented and self-motivated individual with a passion for spaceflight. I enjoy learning new things and staying abreast of today’s rapidly changing technology. I easily integrate into a team setting and can also operate on my own when necessary. I am seeking an entry level mechanical engineering position where I can continue to learn and develop my engineering skills.
Education:
California State University, Sacramento
-Bachelor of Science in Mechanical Engineering
- ABET accredited
Project Experience:
Weather Balloon Launched Unmanned Aircraft System - Mechanical Engineering Senior Project
-Lead engineer (1 year)
A self-recoverable weather balloon system eliminates the need to recover the weather balloon payload and increases the likelihood of safe instrument recovery. The self-recoverable system consists of an unmanned aircraft system with a GPS guidance system to fly the payload back to a desired landing destination. The challenges presented with this system include designing the aircraft for stable flight and long range capabilities. The aircraft wing is engineered with efficient gliding and flight abilities while a strong chassis system is used to protect internal components. The system is designed to be adjustable to the users’ needs by incorporating a versatile payload bay, propulsion system for extended range, camera mount, and programmable altitude release. Analysis of flight dynamics and FEA were used to verify the flying ability and structural strength of the aircraft system. Altogether, the self-recoverable weather balloon system creates a much more user friendly experience than previous weather balloon research methods.
NASA’s Project Morpheus Research - National Space Grant College and Fellowship Program
A Working Model 2D representation of the lander was provided to become familiar with the kinematics of the system and motion of the fuel. The model simulated a tether test with the lander swaying. When the lander sways back and forth it causes the vehicle to roll and the fuel to slosh inside the spherical tanks. When the fuel sloshes it destabilizes the lander and makes it very difficult to maintain the desired thrust vector. The kinematic relationships between the lander and the fuel tanks were determined using the principles of dynamics. Once determined the kinematic relationships were used to generate bond graphs which were then used to model the center of mass position of the fuel inside the spherical tanks. The research was used by NASA in conjunction with other research to develop a thrust vector control system capable of compensating for the sloshing effect of the fuel.
