Objective: Providing mechanical & technical consulting to meet client needs related to engine research, development and testing for the Automotive & Aerospace Industries. Services include engine development, engine testing, test cell specification, installation, instrumentation, and data acquisition and control.

Summary: Highly experienced in the research, development and testing of internal combustion engines, propulsion systems, and turbo-machinery. Knowledgeable of computers, especially related to software development, data acquisition, test instrumentation, test methods, test control, modeling, data reduction and analysis. Engineering manager & project management experience related to project execution, research & development, product development & testing, and manufacturing support. Experience includes complete project execution from client interface, test requirement definition, and proposal generation, to test execution, data analysis and reporting. Includes promotion to, and interface with, single and multiple clients.

Experience:

       Performing mechanical and technical consulting services for firms on a contract basis. Mechanical and technical services provided include:

  Conducted research and development on internal combustion engines, including mechanical component selection, combustion design/development, performance/power development, emissions testing, engine durability testing, and alternative and conventional fuels testing.

  Conducted engine testing and development on a 7.6L Navistar natural gas alternative fuel engine.

  Managed numerous engine development/durability projects and test cell activities, including a high-speed engine fuels test program evaluating Formula 1 racing fuels.

  Conducted design, development, test and calibration of electronic fuel control systems for gasoline and alternative fuel engines. Adapted test cell-developed engine electronic controls to an engine running in a vehicle.

  Experienced with automotive engine high-speed cylinder pressure data acquisition and analysis.

  Conducted engine testing with cylinder pressure analysis of peak pressure and location of peak pressure to determine effects of spark timing and air-fuel ratio in different combustion chambers.

  Specified test cell instrumentation, interface to data acquisition, and calibration requirements

  Specified and supervised the installation and testing of engines in dynamometer test cells, including the specification of dynamometers, drive motors, and the design of driveline components.

  Identified testing needs, developed test cell specifications, and designed engine test cells for clients.

  Specified & installed PCs for data acquisition, data analysis, and test/process control of engine test cells.

  Knowledgeable of basic control theory, and proficient in the use of National Instruments hardware and LabVIEW software for test and control purposes, specifically for engine test cells and test stands.

  Wrote LabVIEW software for engine test cell data acquisition and control, including data analysis.

  Wrote LabVIEW software for high speed cylinder pressure data acquisition and analysis.

  Specified National Instruments hardware for test cell data acquisition, including instrumentation to work with the data acquisition system (temperatures, pressures, fuel flow, engine speed, etc.).

  Wrote LabVIEW software for a hydraulic pressure test stand, controlling pressure cycles to a test article. Software controlled pressure, frequency, pressure waveform, and recorded data for each cycle.

  Designed, specified, and supervised the construction and commission of a dedicated turbocharger test facility.

  Proficient with turbo-machinery, and in turbocharger test methods using SAE standards.

  Presented technical reports and technical presentations to clients for project status and final reporting.

  Designed and developed gas turbine engine computer software models for aircraft flight simulators, including helicopter turbo-shafts and fighter aircraft turbofans.

  Designed new engine thermodynamic models for improved simulation fidelity and performance.

  Modeled various turbine engine fuel control systems, learning their logic and functions.

  Specified requirements for, analyzed, and reduced engine flight test data for use in computer models.

  Integrated individual engine software models within complete aircraft flight simulator systems.

  Responsible for design, procurement, and testing of experimental gas turbine engine components for military engines used in fighter aircraft.

  Tasks involved planning, scheduling, cost tracking, coordination of support group efforts, procurement, assembly, testing, and evaluation of experimental aircraft gas turbine engine hardware.

  Provided engineering support for field problem investigations, component failure analysis, production assistance, and field inspection and evaluation of lead-the-fleet hardware.

  Technical lead on AIRPRINT project for the Air Force; performing front-end analyses on the processes, methods, and software tools to guide the conduct of Human Systems Integration (HSI) efforts.

  Provided technical input and engineering analysis where required to support the project goals.

  Undergraduate research assistant on NASA Lewis Research Center sponsored-project Reformed Methanol as an Automotive Fuel, testing alternative automotive fuels on a dynamometer-mounted engine.
