Jim Harp is a veteran of power plant engineering. His involvement ranges from research of reciprocating engines for propeller driven fighter aircraft; to turbojets, ramjets, supersonic combustion ramjets and rockets motors. He has done finite chemical kinetic research on temperature and combustion systems; and high temperature combustion research on fixed volume combustion drivers for Mach 6-12 wind tunnel facilities. In the past 26 years, he has been active in developing advanced turbo-charged and turbo-compounded engines for the U.S. Army Tank-Automotive Command, Teledyne Continental Motors, John Deere, DARPA and NASA. He began his career as a P-47 fighter pilot in the Europe during World War II, also designing and installing K-24 and K-25 cameras on P-47's. After the war he graduated with a B.S. degree in Mechanical Engineering from the University of Illinois. He became active in the research and development in technical intelligence gathering as a reserve officer in the U.S. Air Force Reserve from which he retired with the rank of Colonel. In his typical enterprising way in 1946 he purchased a surplus P-38 modified it for racing, entered it in the Bendix Transcontinental Trophy Race and won 5th place and $1,500 by flying from Van Nuys to Cleveland nonstop in 5 ½ hours. In 1949 he installed a P-63 engine in a P-39 and entered it in the Thompson Trophy Race at Cleveland during which he dropped out due to structural failure of the canopy. He has wide experience in program management of major programs such as: ·         Development of advanced turbochargers for high altitude, spark ignition, aircraft engines. ·         Design and development of advanced variable diffuser centrifugal compressor for diesel engine turbochargers. ·         Design and development of a 6-cylinder turbo-compound diesel engine. ·         Study of low emission vehicle power plants using gaseous working fluids. ·         Design and development of a 500,000 Joule hotshot tunnel. ·         Development of packaged liquid air augmented rockets. ·         Experimental evaluation of a SCRAMJET integrated combustor nozzle system. ·         Determination of effective recombination ratio in high temperature exhaust expansion systems. ·         Turbojet performance and operation at high altitudes using hydrogen and JP-4 fuels. ·         The control of combustion screech in turbojet afterburners. Professional Experience: 1969 - Present            President, Thermo Mechanical Systems, Canoga Park, California Duties include directing analytical and experimental turbo-machinery and engine programs. Programs include design and development of advanced backswept compressor impellers, variable area diffusers for centrifugal compressors, advanced radial inflow turbines, variable area nozzles for radial inflow turbines, exhaust energy recovery in advanced diesel engines by turbo-compounding, and exhaust emission control in automotive power plants. 1956 - 1969                 Manager, Advanced Technical Staff, The Marquardt Co. Van Nuys, CA Duties included supervising analytical and experimental research on propulsion systems and components. Programs included research on hypersonic ramjets, SCRAMJETS, low volume ramjets, ejector ramjets, rockets, air-breathing inlets, subsonic and supersonic combustors, and non-equilibrium effects in exhaust nozzles. Managerial duties included planning and organizing research programs, monitoring progress reports and budgets, preparing R&D proposals, procuring scientific personnel, and coordinating with other companies and governmental agencies. He was responsible for the design, installation, and advanced development of Marquardt’s 500,000 Joule Hotshot Tunnel Facility. And served as Project Engineer on an exploratory development air-to-air missile program (PLAAR) for the U. S. Naval Weapons Center. In addition to directing the development of an efficient flight weight, flight type, full duration propulsion system, he coordinated the definition of the non-propulsive subsystem (airframe, guidance and control, warhead, etc.) with the airframe subcontractor. 1948  to  1956                                                               1948-1952                   National Advisory Committee for Aeronautics (NACA), Cleveland, OH He served as an Aeronautical Research Scientist in the Engine Research Division performing analytical and experimental studies on various methods of turbojet engine research programs, some of which he conceived and initiated. The engine studies in these programs included the J-33, J-34, J-47, J-65 and J-79 jet engines. These studies included injection of various liquids into the turbojet compressors and combustors for the purpose of thrust augmentation; use of special fuels and slurries to provide increased thrust, longer range and higher altitudes; development of high performance afterburners; and finding a solution to the afterburner combustion screech problem.
