Mr. Pish joined UT-CEM as an undergraduate in 1992, and began working full time as a mechanical engineer in 1996. His research activities have included the development and testing of advanced converters and interconnections for pulsed high power rotating machines and a representative lab based distributed microgrid. He has led several prototype rotor assembly efforts including a 3MW, 15 krpm generator and two 12 krpm pulsed alternator rotors. Mr. Pish also has experience with the design, manufacture, assembly, and testing of advanced carbon composites including high performance rotor bandings and growth matching arbors.
US Army, Electric Gun Program (1996-2000) Advanced converter packaging and interconnections including the design and fabrication of a 1 MJ capacitor bank for switch development testing.
Federal Railroad Administration, Advanced Locomotive Propulsion System (2001-2004) Led the assembly of a 3 MW, 15 kRPM generator including an 800+ degree F thermal fit of the rotor laminations to shaft.
US Army, Electric Gun Program (2004-2010) Helped lead the assembly of two 12 kRPM pulsed alternator rotors including advanced composite structures. Managed budget and schedule for five year, $10 million program.
UT McDonald Observatory, Hobby-Eberly Telescope Dark Energy Experiment (2010-2011) Led the test stand assembly for lab testing of the telescope tracker, responsible for work platforms and work at height safety.
US Navy, Electric Ship Research & Development Consortium (2012 to present) Led UT-CEM microgrid tests to demonstrate important aspects of electric ship architectures. Helped evaluate candidate electric ship architectures for future navy vessels. Analyzed advanced power solutions for future and existing electric ships including electrical/mechanical hybrids.
