1994 to date. Research Consultant,
Inc. Cary, North Carolina. Research and development of vehicle
simulation and accident reconstruction computer programs and tools
1980 to 2008, retired. Staff Scientist, McHenry Consultants,
Inc., Cary, North Carolina. Technical Duties: Investigation of highway
accidents. Application of analytical and experimental techniques to the
reconstruction of vehicle and occupant dynamics in highway collisions.
Evaluation and analysis of vehicle defects and failure modes. Performance

1978 to 1980. Staff Scientist, Research Engineers,
Inc., Research Triangle Park, North Carolina. Technical duties: Application
of analytical and experimental techniques to the reconstruction of vehicle
and occupant dynamics in highway collisions. Evaluation and analysis of
vehicle defects and failure modes. Performance of research related to highway
1961 to 1978. Staff Scientist,
Cornell Aeronautical Laboratory, Inc.), Buffalo, New York. Technical duties:
As a Staff Scientist with Calspan Field Services, Inc., and previously
with Calspan Corporation, Mr. McHenry was responsible for the technical
direction of a variety of research projects related to the improvement
of highway safety. He was involved in the application of analytical and
experimental techniques to the problems of occupant protection in collisions
and he analyzed automobile dynamics in single vehicle accidents and in
violent evasive maneuvers. He also served as the Principal Investigator
on the development of techniques for analytical reconstruction of highway
accidents [Simulation Model of Automobile Collisions (SMAC) and Calspan
Reconstruction of Accident Speeds on the Highway (CRASH)].
Mr. McHenry developed techniques for study of physical
criteria for roadside structures and cross-section designs by mathematically
modeling the dynamics of single vehicle accidents [Highway Vehicle Object
Simulation Model (HVOSM)]. He performed analyses and developed computer
simulations of the dynamics of automobile braking and of the ride and steering
dynamics of the Westinghouse Transit Expressway Vehicle. He studied advanced
technology applicable to highway transportation in the Boston-Washington
Corridor in 1980. He developed a nonlinear mathematical model of the automobile
crash victim and mathematical models of highway guardrails and test vehicles
for simulation of impact.
1960 to 1961. Technical Advisor, American Machine
& Foundry Company, Greenwich, Connecticut. Technical duties: Mr. McHenry
was technical advisor on the design of vehicles for aircraft cargo loading
(Air Force 463L System).
1956 to 1960. Senior Design Engineer, Ford Motor
Company, Dearborn, Michigan. Technical duties: Senior Design Engineer and
Project Engineer on programs involving experimental hydropneumatic suspension
vehicles, air suspension vehicles, and stroke-sensitive shock absorber
design and development. Member of the Ford Advanced Ride and Handling Committee.
1953 to 1956. Chrysler Corporation, Highland Park,
Michigan. Technical Duties: Participated in various experimental suspension
and chassis component design and development programs. He also served as
a mathematics instructor in calculus, analytic geometry and algebra (Lawrence
Institute of Technology, Chrysler Institute, Detroit).
