Ballistic system technical description

Software for use in ballistic laboratories in connection with timer modules, Kistler Instruments, National Instruments Data Acquisition and other various equipments.

Standard procedures :

The software complies fully with :
  • CIP decisions, text and tables, edition 2007.
  • NATO Epvat AC/225 testing procedure
  • ANSI/SAAMI Performance Standards books Z.299, edition 1992-1993 (most recent).
Target applications :
  • Proofing houses of any CIP member countries.
  • Military and law enforcement laboratories
  • Schools & Research and Developments laboratories.
  • Ammunition manufacturing
  • Impact studies, helmets, waistcoat, etc.

Compatibility with existing equipments:

Our software is compatible with the following type of equipments :

Velocity cells :

Deby Laserblade, Oehler Research, Drello, Microbase or any kind providing a standard 0-10 V triggering signal. Connections with RG-58 cables and BNC plugs.
Signals adaptation upon request.

Action time: Typically using a ring with a pressure transducer or a laser system.

Transducers :

Any type, generally Kistler or PCB as long as they are connected to one of the charge amplifier listed below.

Charge amplifiers :

  • Kistler 5015A (recommended), 5011, 4643, 5041 5044A, 5058A
  • PCB 462A, 462B53, 400A21, 421A25
  • PM 2000
  • Bruel and Kjaer 2635.
  • Columbia Research 4601.
  • Endevco 2721A, 2721B.
Other types available upon request. We do sell Kistler worldwide.

Acquisition electronics:

Low cost version: Usb link to Kistler charge amplifiers acting as simple and accurate peakmeter. Embedded RISC microcontroller linked via Usb for velocity measurements. This version does not provide pressure signal analysis and other related functions.

Advanced version : The electronics is based on state-of-the-art National Instruments acquisition boards and peripherals. Upgrade from older electronics is possible as long as the output signals are standard (please ask us for checking)

Signals conditioning (advanced version only):

National Instruments signal conditioner with built in electronics for :
  • Triggering on firing pin, pressure rise, muzzle flash or velocity1 start.
  • Velocities signals crop to TTL level.
  • Pressure channels connection and shielding.
  • Forwarding of "chain ready" signal for proper timeout operations.
  • Interfacing to acquisition board via flat cable and NI connector 68pins VHDCI.
National Instruments acquisition board :

This board is mounted in the processing computer:
  • Pressure sampling up to 1.25 MSamples/sec. Can be set into one of the following configuration :
    • One channel 1.25 MSamples/sec for ultra high accuracy R&D measurements.
    • Two channel 500 KSamples/sec for normal compliance testing.
    • Two channels 500 KSamples/sec for analysis on secondary manometer (only for laboratories - not Standard compliant).
    • Four channels 250 KSamples/sec for various studies with multiple transducers.
    • 8 to 12 channels - 250 KSamples/sec for various studies with multiple transducers ("flute mounting" 2 or 3 boards may be required required).
  • One timer for action time - resolution 80MHz - Quartz accuracy 50ppm.
  • Up to 3 velocity timers - resolution 80MHz - Quartz accuracy 50ppm. (up to 3 boards - 12 velocity channels for specific trajectories-velocities analysis).
  • The board is delivered standard with National Instruments NI-DAQmx drivers compatible with Microsoft Windows 7.
