During that period he led the high-efficiency ceramic turbine development, introduced innovations in combined heat and power, advancements in low-emission combustion for alternative fuels, and developments in recuperators.
Jim holds 17 patents relating to recuperators, combustors, and gas turbines.
Jim began his career at Lockheed/Sanders, working on gas turbines, solar-dynamic space power, thermal storage, Stirling engines, and alkali metal heat pipes.
From 1992 until 2001, Jim led the Ingersoll-Rand/NREC Energy Systems Business Unit and was responsible for the technical direction of the Power Works 70 and 250-k W microturbines, recuperators, and other advanced energy system development programs.
Jim has a BS in Mechanical Engineering from the University of New Hampshire, and completed the Ingersoll-Rand Executive Management Training Program.
Jim is an avid bicycle and ski racer as well as cabinet maker when not working at Brayton.
Malcolm is Brayton’s chief expert in solid modeling and computer-aided design, supervising a team of designers and draftsmen performing these activities.
Tom is Brayton Energy’s expert in thermodynamic cycle analysis and performance modeling, as applied to gas turbines and other advanced engine systems.
Formerly at Ingersoll-Rand, he led design efforts associated with high efficiency radial inflow turbines and compressors.
Prior to joining Brayton, Jim was the Director of Recuperator Products at Ingersoll-Rand and led the highly successful recuperator program from concept to full production of several successful products including the Rolls-Royce/Northrop-Grumman WR21 recuperator and the IR-70 and 250 k We microturbine recuperators.
Jim also led several recuperated gas turbine integration test programs for IR, including the KHI 700-k We, the Turbo Meca TM1800, and the Siemens-Westinghouse hybrid SOFC programs.
His 25-year professional career covers a wide range of analysis and testing techniques, including those for propeller blade dynamics and acoustic radiation. He has over 22 years of mechanical engineering experience focused on gas turbine hot-section design.
