Evan Helmeid

Evan Helmeid is a Systems Engineer in the Propulsion Department at Dynetics Inc. in Huntsville, Alabama. In 2011, he received his B.S. from Purdue University in Aeronautics and Astronautics with concentrations in Spacecraft Design and Dynamics and Control. Currently, he is seeking his M.S. in Aerospace Systems Engineering at the University of Alabama in Huntsville part time. During his time at Purdue, he interned twice at NASA Langley Research Center in Hampton, Virginia, and once at NASA Marshall Space Flight Center (MSFC) in Huntsville, Alabama. At NASA, he developed software for the Aircraft Noise Prediction Program (Langley) and served as the team lead of a team of interns developing a test program for the Rocket City Space Pioneers Google Lunar X-Prize team (MSFC and Dynetics). At Dynetics, he has worked on the Stratolaunch program (a Paul G. Allen project), Shadow unmanned aerial vehicles, and the Space Launch System Core Stage. His primary job functions include systems engineering; requirements management; configuration management; safety, quality, and mission assurance; and proposal development. He can be contacted at erhelmeid (at) gmail (dot) com.

During my undergraduate studies at Purdue, I had the opportunity to be involved in Sigma Gamma Tau in a variety of roles, serving as the Fundraising Chairperson, Social Chairperson, and ultimately as the Vice President. During my tenure, I increased the cash flow for the organization enabling more chapter events to occur, organized the inaugural regional meeting for the organization facilitating communication between local chapters, and oversaw the pledge process for over 30 new members that allowed them to learn about the organization while making a meaningful contribution to the chapter and school. My involvement with Sigma Gamma Tau was a major contributor to securing summer internships as a Design Engineer for Gulfstream as well as Boeing. These experiences enabled me to return to Boeing as a Structural Designer on the 747-8 High Performance program in Seattle, working primarily with the aft Wing to Body Fairing. I have also been able to continue my education with Purdue as a distance Graduate student in Aeronautical and Astronautical Engineering, focusing on structures and systems. Additionally, I am in the process of earning my Professional Engineering degree, passing the Fundamentals of Engineering exam in Spring 2013.

I joined Sigma Gamma Tau at the end of my sophomore year at Purdue. My pledge project was to aid in the construction of the Pledge Keys, which were made out of poor quality plywood at the Aerospace Sciences Laboratory. In my junior year, I took charge of the Pledge Key Committee and completely changed the process, finding a way to craft them out of aluminum in a financially responsible manner. I became President of SGT starting my senior year. During my presidency, SGT followed the framework that the previous executive board established and continued to make improvements to our sources of revenue and social activities. I left Purdue in 2012, accepting a job at Lockheed Martin Missile and Fire Control as a Systems Engineer - Aerodynamicist in Orlando, FL. At Lockheed I work in the Aerodynamics Center of Excellence where I get to touch almost every program since nearly all of our products require aerodynamic analysis. I mostly run CFD analysis on a variety of missile systems such as Hellfire, Longbow, and several Independent Research and Development (IRAD) programs, but I have also built aerodynamic models that are used in our simulations, performed safe separation and closest point of approach analysis, and supported wind tunnel tests for programs like JASSM and its derivative program LRASM. After working at Lockheed Martin for a year I enrolled in a master's degree at Purdue as a distance learning student in the AAE department.
