Warhead Technology

To provide advice and expertise on Warhead Technology related munitions safety topics

Interests include relevant science and technology related to: warhead mechanics, detonics and reaction mechanisms of warheads, accidental initiation.

Current area of interest / work: 

Topics of interest include:

  • Detonation Physics and Chemistry;
  • Munition reaction mechanisms and models;
  • Energetic materials subscale testing technology;
  • Prediction of munitions response to IM threats and setback;
  • Warhead design for performance, IM and production;
  • Munitions Testing and qualification;

As the current TSO, I have interests in the following topics: Munition design and analysis; Policy, Standards, Safety, Manufacturing, Science and Technology, and Insensitive Munitions

The Warhead Technology TSO is the MSIAC point of contact for Insensitive Munitions. As such, he routinely briefs IM Policy and the technologies associated with Insensitive Munitions. This is done in close collaboration with the Energetics, Propulsion and Systems TSOs.

Science Technology and Procurement is a standing article in the MSIAC newsletter. This section of the newsletter covers the spectrum of breaking news. It highlights conventions, conferences, trade and air shows that were hosted and some pertinent details from them. It identifies recent contracts, procurements, business arrangements and joint ventures of interest to the munitions community. And finally it discusses Science and Technology related to munitions safety with recent developments, tests and trends.

My current Work Elements are:

  3. Methodology for Gun Launch Setback



  1. TEMPER: Toolbox of Engineering Models to Predict Explosive Reactions

TEMPER is and MSIAC tool that contains a library of initiation models which has not been updated for some time.  The primary TEMPER objects are grouped into four categories: stimuli, which may trigger a reaction; mitigation, the environment that may transform the initial stimulus; structures, which contain a energetic material liable to react; and models, which describe the munition reaction to a stimulus.  This work is updating TEMPER to run on current Microsoft Windows platforms and augment the modeling capabilities.


  1. NEWGATES: Nifty Excel Worksheets on Gap TESts

NEWGATES in an MSIAC tool that contains information related to gap tests.  The NEWGATES program and database have been developed in Excel and runs on a personal computer in the Microsoft Windows environment.   It can be used to compare gap tests results and/or calculate critical initiation pressure and critical initiation time.  It provides modellers with a flexible research tool including references and contains data required to validate models.  It provides the IM community with 6 databases: gap test specification, pressure calibration curves, time calibration curves, shock curvature calibration curves, 1455 gap test results, +250 Hugoniots.


  1. Methodology for Gun Launch Setback

Premature explosion of gun launched munitions continues to be a concern.  The introduction of new energetic materials and Insensitive Munitions technologies into gun launched munitions have repeatedly met with difficulties arising from a lack of understanding of the mechanisms which may lead to the premature ignition of the explosive fill during the launch of a projectile. Without this understanding, it is impossible to assess the effectiveness of design and formulation changes proposed to improve the premature rate. There exists, therefore, a need to identify ignition mechanisms and to determine how they are affected by parameters which characterize the projectile at the time of launch.  This work element is investigating the use of Gun launch simulators to assess suitability for gun launch.  The work includes: review of setback  test used and the methodology employed, description of the physical process leading to ignition, the role of material properties, and gaps in capabilities.
