Restraint System Development
Tire Design and Development
Wheel Design and Development
I conducted an extensive study of rollover probability following a testing rollover occurrence with a modified vehicle. This study led to my knowledge of the primary physical factors relating to rollover and the sensitivity of each factor.
During my racing experience I have personally experienced 2 rollover accidents.
I have investigated rollover incidents that have occurred during testing of production vehicles.
Airbag/Restraints System Development:
As Chief Program Engineer of the Ford GT, I was responsible for the restraint system design and development program for the Ford GT, which included airbags. This also included evaluating the potential use of 4-point safety belts. This was not pursued due to complications of the system resulting from regulatory requirements for one hand operation of the safety belt system.
At McLaren I directed a program to modify and certify a production vehicle for new changes to the FMVSS 208 regulation (advanced airbags). This involved new locations and operating requirements for the airbags, and new application of the safety belts. This involved the use of the simulation tools LS Dyna and Madymo. I also directed all restraint system design, analysis and development for the Mercedes Benz- McLaren SLR Roadster.
I was the sign off engineer for the restraint system for the Saleen S7, which was given a waiver to allow an FMVSS 208 compliant restraint system without airbags. I performed the safety belt anchorage testing, and then also redesigned the safety belt mounting after the original design failed to meet the test requirements. (The original design was done by an outside company prior to my arrival at Saleen).
I was responsible for the design of the restraint system for the Dodge Viper GTS/R.
I have performed seat belt tensile tests while I was a Staff Engineer at Minicars.
I was the design release engineer for the Aptera seat. The Aptera seat was an existing seat that was modified to suit the Aptera requirements and to include the feature of the safety belt buckle attached to the seat, which was a feature the existing seat did not have. I directed the initial FMVSS 207 development testing for this seat. As Chief Engineer for the Ford GT I was responsible for the design, development and certification of the seat as well as all other systems.
I have been the sign off engineer for the vehicle dynamics characteristics for 8 production vehicles. These characteristics include vehicle ride, handling and braking performance.
(Shelby Charger, Shelby GLH, Shelby GLH-S, Shelby Lancer, Shelby CSX, Shelby CSX-T, Shelby Dakota, Dodge Viper)
I was the Chief Engineer responsible for the overseeing and approving the work of many vehicle dynamics engineers during handling development of 5 production vehicles. In all these programs I was always the test driver in the final tuning process.
(Saleen S7, Saleen S281, Saleen S281E, Ford GT, Mercedes McLaren SLR 722 Edition)
I was the Author and Instructor for the Vehicle Handling and Performance modules of the Chrysler Synthesis Awareness workshop (an internal course taught to all Chrysler engineers)
Member of the Chrysler Vehicle Dynamics "Tech Club" and I was a recognized expert within Chrysler for
Vehicle Dynamics evaluation as well as all other types of vehicle evaluations.
Test driver for numerous production and prototype vehicles. Over 20 years of automotive race driving, both amateur and professional. Personal instructor and mentor for many engineers, racecar drivers, and average drivers.
I have used data acquisition equipment extensively during the development of vehicle dynamics characteristics. I developed a specific data acquisition package during the Viper handling development this included using sensors such as displacement and velocity sensors for shock absorbers, rate sensors for yaw and angle sensors for pitch and roll. I have also specified and used Datron non-contact speed sensors.
I have performed calibration of engine controllers for the purposes of vehicle dynamics tuning. This was primarily to use the engine parameters to manage the torque output of the engine in various conditions to improve vehicle stability due to torque steer of a front drive vehicle. (This was also used as a strategy for transaxle durability in addition to the vehicle dynamics attributes.) I have also specified engine calibrations that improved handling characteristics of rear drive vehicles.
I was the Chief Engineer responsible for the complete vehicle structure of the Ford GT. I established the structural concept and was responsible for all engineers and suppliers completing the design.I have directed many FEA (Finite Element
Analysis) studies on vehicle structures including front, side, rear and roof structures. FEA analysis is used to optimize safety and structural performance. I have analyzed the implications of legislative requirements (in many vehicle markets) and I have set specific structural targets in areas that I felt that the legislative requirements were not sufficient. (McLaren roof crush standard, Ford GT dynamic side impact and roof crush, Ford GT seat belt pull to FIA appendix J standard)
I have designed many safety roll cages for racecars.
Wheels Design and Development:
I was the Sign off Engineer for both the primary road wheels and the temporary spare wheel for the 1996 model year Dodge Viper GTS. I was responsible for the design, testing and development of the road wheel.
As Vice President of Engineering at Saleen Inc. I was responsible for a NHTSA recall concerning the road wheels for the Saleen S281. This entailed analyzing wheels that had failed in service, determining the issues and making the decision regarding the recall. The issue was a supplier manufacturing defect.
As Chief Engineer of the Ford GT I was responsible for supervising many aspects of 2 different wheels, standard and optional. This included directing employees for the design, development and those responsible for supplier selection, quality control and service.
As the Engineering Director at McLaren I was responsible for design and development of a new forged aluminum wheel with the goal of minimum weight. This involved extensive finite element analysis and testing.
I was a member of the Chrysler Corporation "Wheel tech club".
Tire Design and Development
Over a 25-year period, I have performed extensive tire testing for many applications both for road cars and racing cars. I have been the final “sign off” for the tire design for many production car applications.
I worked closely with Goodyear to develop a special tire for the first front wheel drive vehicle to exceed 1 “G” of cornering ability.
I worked closely with Michelin on the design and development of "run flat" tires prior to any production application. This included involvement in writing of an FMEA for a run flat tire.
I performed testing on many types of spare tires to approve the safe handling characteristics.
I have tested vehicles on a wet “skid pad” that had various combinations of worn and new tire placements.
I was responsible for all vehicle design while working as the Chief Engineer at Saleen. Two designs in particular were specifically for enhancing fuel system safety and reducing possibility of fire. I designed an exhaust system with a particular feature to provide enhanced fuel system safety and integrity. This exhaust system had a feature that allowed it to disconnect from its mounting system and drop down and below the fuel tank. This reduced the possibility that the exhaust system could intrude on an exposed area of the fuel tank. I also designed and implemented a feature to prevent an under hood fuel hose from being damaged by a hot EGR tube.
I was responsible for all vehicle design while working as the Chief Program Engineer for the Ford GT. In this role I defined the design concept and the packaging strategy for the fuel tank. Primary consideration was given to protection of the fuel tank during impacts. I also defined the concept for the fuel hose and filler pipe routing.
During my assignment as the vehicle development engineer for the Dodge Viper I was involved in the development of improvements to resolve three different issues that related to fires. I investigated an under hood fire occurrence while I was working as a vehicle development engineer for Chrysler at the Chrysler/Shelby Performance Center.
I participated in an investigation of an under hood fire situation while I was employed as the Executive Director of Engineering at McLaren Automotive Ltd. This investigation lead to a voluntary product recall for an alternator electrical issue. I was also responsible for engineers that investigated fuel leaks that occurred on production vehicles. These issues were traced to quality control at a supplier and resulted in corrective action at that supplier.I investigated numerous fire issues while I was the Chief Engineer at
Saleen Inc. The resolution of these investigations resulted in my ordering two NHSTA voluntary product recalls. One involved a fuel fed concern and one was an electrical concern.
I have had personal experience with car fire investigations in my own cars. I have had 2 fires on my own cars; both of them were fuel fed fires that were not crash related.
As Chief Engineer I was responsible for the total crashworthiness performance of many different vehicles (Saleen S7, Ford GT, future McLaren products, Viper GTS-R racecar). I have conducted or directed all types of vehicle crash tests: fixed barrier, moving barrier, car to car, impacts into highway attenuating devices, sled tests and static tests. I have been responsible for the design, application, testing and certification of the components that are the primary contributors to vehicle crashworthiness. This includes bumpers, crash structures, steering columns and steering wheels, seats, restraints, windshields and glazing.
I have directed the design concept work for the application of a Double Clutch Transmission (DCT) for a mid engine installation. This was done while I was the Executive Director of Engineering at McLaren Automotive Ltd. over a 3-year period. The concept work was done with 3 different suppliers of drive trains. I also directed a concept design to use a transaxle in place of the transmission in the Mercedes/McLaren SLR.
As the Chief Engineer I was responsible for the design of a new transaxle for the Ford GT. This included selecting the supplier and all targets for cost, durability and testing. I held this responsibility for a 2 year time period.
During my 7 years working at the Chrysler/Shelby Performance Center I was involved in the design of 2 types of AWD systems in 3 different vehicle applications. These were used for both Automatic and Manual transmissions. This included fabrication and testing of prototype systems. The result of this work was the prototype for the Chrysler AWD Minivan which started production in the early ‘90’s. I also developed continuous improvements to the strength and durability of current Chrysler FWD transaxles when used in higher output applications. This includes a higher strength end plate which reduced the amount of deflection and provided a more reliable control of the shaft end play.
I also designed and developed a limited slip differential for Chrysler front wheel drive applications. This was a unique housing for modified gear components. I was also responsible for the manufacturing and assembly process of this differential.
Development and testing:
I was responsible for all in-vehicle testing for the Dodge Viper application of the Borg Warner T56, as it’s first application. This included testing for shift quality, clutch capacity, fluid temperature and durability. As program manager of the Viper GTS/R program I was responsible for the transmission development of the T56R, which succeeded at completing and winning the Lemans 24 hour race for 3 consecutive years (1998-2000).
Over a 7 year time period I designed, tested, developed and assembled racing transaxles for numerous race teams.
I have investigated many defects of prototype test vehicles that have occurred primarily during the test phase of a vehicle development program. I have in many cases created or recommended improved designs for retest and if successful, use in the production vehicle.
As a Suspension Design Supervisor I was involved in all aspects of design for steering and suspension systems. I directed a group that was tasked to write an FMEA for suspension system design.
I have performed the “tuning” of the power steering system for many vehicles.
I was responsible for development of the braking system for the Dodge Viper (1989-1992). This included developing a matrix of various configurations and determining the cost trade-offs for performance.
I designed and developed an aftermarket ABS system that could be fitted to Dodge Vipers. The system was marketed under the brand name “Snake Brakes”.
I designed and configured an ABS system for the Saleen S7. I also redesigned the brake pedal system.
As an Engineer at the Chrysler/Shelby Performance center I performed the brake bias testing and specified the proportioning valve to be used for all the Shelby production vehicles. I participated in the design of a rear disc brake for use on Shelby vehicles. This was the first use of a “drum in hat” at Chrysler Corporation.
As Chief Engineer I was responsible for the overall design and development of the braking system and the
ABS system for the Ford GT.
Other:As Chief Engineer responsible for design and development of complete new vehicle programs and variants of existing vehicles I have been responsible for the design of the total vehicle having supervised the design and development of every vehicle system at varying levels of detail.
I have done testing and research into many types of highway safety impact attenuating devices.
At Chrysler I was sought out by many co-op students for training and mentoring in the role of vehicle development.
