Why We Call It The James Bond Spiral Jump by McHenry

Post by MSI »


I've had some folks asks why we call it the 'McHenry James Bond Spiral Jump'
  • Back in the 70's Raymond R. McHenry came up with the idea for the stunt as a test of the validation of the HVOSM 3D vehicle simulation program
    • HVOSM is included in the McHenry Software msmac3D program
  • Ray invented and designed the stunt (see patent and papers below).
  • For the 2018 Jaguar e-pace Rollout stunt we had fun revisiting the earlier stunt and modifying things to accommodate the 2018 Jaguar e-Pace.

    For Additional Information:
    • 1969: IME paper on hvosm (he won the IME Safety Award) paper: An Analysis of the Dynamics of Automobiles During Simultaneous Cornering and Ride Motions
    • 1971: First public performance of the Astro Spiral Jump at the Houston Astrodome on Jan. 15,1971

    • 1974: SPIRAL JUMP STUNT APPARATUS Patent 3801021 Inventor: Raymond R. McHenry
    • 1974: James Bond Movie: The Man with the Golden Gun is released
      • Having seen/heard about the traveling American Thrill Show Stunt the Bond folks had Ray redesign the stunt so an AMC Hornet could be used as a REAL STUNT in a Bond movie. In the movie Bond jumps a Hornet over a creek in Thailand
    • 1976 Ray wrote the paper: The Astro Spiral Jump-An Automobile Stunt Designed via Simulation
      • which included a description of Ray's concept and invention of the stunt:
        • "As a part of the HVOSM development process, Calspan employed the services of professional stunt drivers in 1968 to perform maneuvers and stunts with an instrumented vehicle and, thereby, to generate vehicle response data in violent maneuvers for use in investigating the validity of the computer simulation.

          One of the included stunts was a fifty foot jump from a take-off to a receiving ramp. The degree of achieved correlation between analytical predictions and experimental measurements was found to be remarkably good in all of the included maneuvers and stunts.

          At the time, it was jokingly pointed out that Calspan had unintentionally developed a capability for the design and staging (i.e., via animated perspective displays on motion picture film) of auto thrill shows. A related, "far out" suggestion was the design of ramps to produce a combination of jump and rollover (i.e., a "spiral" jump), such that the stunt car would land on its wheels after passing over an obstacle in an inverted condition.

          Subsequent to completion of development and validation of the HVOSM simulation in 1970, the thrill show ideas were given somewhat more serious consideration. Such an application would constitute both a challenging dynamics problem, similar in nature to a particularly violent single vehicle accident, and an attention-getting demonstration of Calspan capabilities. It also had the appeal of a "fun" project to relieve a steady diet of crash protection studies.

          In November of 1970 the author contacted Mr. W. J. Milligan, Jr., President, J. M. Productions, Inc., of Hamburg, New York, regarding his possible interest in the design of a new auto thrill show stunt and/or the establishment of speed and dimensional tolerances for existing stunts . The occasion of the contact was a newspaper item about Mr. Milligan's organization of a new national auto thrill show. As a result of subsequent discussions , J. M. Productions gave Calspan a purchase order to support an analytical study of the spiral jump stunt concept."
