Contact Brian
Brian Parrelli is deeply passionate about turbomachinery, and this is evident in his work as Principal Aerodynamicist at L.A. Turbine.  Since joining in 2014, Brian has played a key role in the design and development of the turbine and compressor stages used in L.A. Turbine’s turboexpander fleet.

Brian draws from his extensive experience gained in the aerospace industry doing aerodynamic design and development work on turbomachinery for aircraft and rocket engines.  As Principal Aerodynamicist, he is responsible for the complete design of the turbine and compressor stages, including performance prediction, Computational Fluid Dynamics (CFD) analysis, flow path definition, 3D blade design, and performance testing.  He also is instrumental in supporting the applications team during the proposal phase by running and maintaining his own machine power balance code.

Prior to joining L.A. Turbine, Brian worked as a Senior Engineer at Aerojet Rocketdyne (formerly Pratt & Whitney Rocketdyne), where he performed design and analysis of turbine and pump stages for various engine programs, including the Space Shuttle and the PW Geared Turbofan.  He also gained significant R&D experience supporting the Energy Systems department, completing numerous conceptual design studies aiming to develop new technology in the emerging field of Supercritical CO2 power generation.

Brian’s passion for turbomachinery also inspires him as an inventor, author and teacher.  He is responsible for numerous company patents, publications, and trade secrets in turbomachinery design and development.  He has also created a curriculum on commercial CFD software and its application to modern engineering design.

Brian Parrelli holds a Bachelor of Science and a Master of Science in Aerospace Engineering from the University of California, Los Angeles.
