Mr. Greg Meholic is member of the AIAA Nuclear and Future Flight Propulsion Technical Committee, a regular chair of the Future Flight sessions at the Joint Propulsion Conferences, and has published a number of papers about faster-than-light travel, the construct of space-time, and the grand unified theory. He currently supports space launch vehicle concept development and propulsion system studies for the US Government. During the past seven years, Greg has worked on upper-stage cryogenic rocket engine performance and design assessments for the US government space launch program as well as launch vehicle operational requirements, launch systems and designs, and other advanced propulsion projects. Mr. Meholic was previously employed at General Electric Aircraft Engines where he worked in gas turbine performance and preliminary design, component life analysis, mechanical design and advanced concept development. His work on the pulse detonation engine program there allowed him to develop four patents on PDE valve concepts and applications. Mr. Meholic is also a lecturer at both UCLA and Loyola-Marymount University on Propulsion Systems for both aircraft and spacecraft.
