Missiles and smart ammunition have to accomodate the new specific features of theaters of operations. With CHRONOS, an innovative acceleration generator we developed for our laboratory, we reproduce powerful accelerations up to 100,000 G to observe and study the behavior of embedded systems under high levels of stress:

  • Components: MEMS (microelectromechanical systems), sensors …

  • Subsystems: IMU (inertial measurement unit), electronic boards, SAU (safety and arming unit), …

HOW DO THE EMBEDDED SYSTEMS IN YOUR EQUIPMENT BEHAVE DURING ACCELERATION AND/OR DECELERATION PHASES?

Extreme but controlled acceleration tests

The sample, from a few grams to several kilograms, is placed inside the “cargo”, a specially designed container we developed. It will then be subjected to sudden acceleration followed by gradual deceleration.

  • No damage to the sample other than that caused by the shock: the cargo is softly recovered

  • Control and repeatability: acceleration profile adjustable in terms of shock intensity and pulse width, with repeatability of ± 2 % for identical test configuration

DISCOVER ALL OUR EXPERTISE IN THE DEFENSE & SECURITY FIELD

State-of-the-art measurement for acceleration phenomena

We focus on developing and using specific measuring equipment in order to collect all the data needed for the most comprehensive and pertinent analysis of the shock experienced by the cargo:

  • Continuous velocity profile measurement using Doppler interferometry, to determine the acceleration profile
  • Measurement of the pressure applied to the cargo, processed to check the coherence of the acceleration profile

THE NUMBER ONE IN SHOCK PHYSICS

Numerical simulation for a unique expertise

We continuously combine tests and numerical simulation to provide the most reliable and comprehensive results:

  • To understand what happens to the equipment inside the cargo

  • To ensure the development of products or subsystems compatible with the challenging conditions experienced by warheads

  • To anticipate the behavior of a complete system, after validating the concept of each subsystem
