Ballistic system technical description

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

Standard procedures :

The software complies fully with :

• CIP decisions, text and tables, edition 2007.
• ANSI/SAAMI Performance Standards books Z.299, edition 1992-1993 (most recent).

Target applications :

• Proofhouses of any CIP member countries.
• 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 :

HPI, 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 camera, pressure transducer or a laser system.

Transducers :

Any type, generally Kistler, HPI 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 instruments worldwide.

Acquisition electronics:

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 :

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 USB to computer.
  

National Instruments acquisition board :

This board is mounted in the dedicated acquisition enclosure:

• 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 CIP laboratories).
• 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 or above.
