Space is a hostile environment for all systems in orbit around our planet, such as satellites, rockets, shuttles, orbital stations and space capsules. With thousands of these drifting around in space, space debris and micrometeorites have been the primary cause of spacecraft mortality for over a decade. And the number of spacecraft in orbit is continuously rising.

THIOT INGENIERIE works together with CNES, ESA and satellite manufacturers to improve the safety of spacecraft. Our experts have developed a gas gun that makes it possible to carry out impact tests at velocities of up to 10.5 km/s (38,000 km/h), a speed nearing that of micrometeorites in space. In our laboratory, we carry out tests that are key to understanding the behaviour of materials subjected to hypervelocity impacts. To meet specific needs, we associate our expertise in physical testing, material characterization and numerical simulation to support you in the development of structures with higher impact resistance and which will generate less debris in the event of a collision.

SHOCK PHYSICS EXPERTS AT YOUR SERVICE TO DEVELOP THE SAFEST STRUCTURES

Dynamic tests + numerical simulation

Why do we always combine laboratory tests and numerical simulation? Because some physical phenomena recorded in the experimental tests may be anticipated by numerical simulation. In turn, the results of the impact and material characterization tests are used to improve and fine-tune our numerical simulation software, for realistic simulation using real-life configurations.

These two areas of expertise mutually enhance one another to provide you with the most reliable and tangible data concerning the behaviour of your materials and structures in the event of a shock.

TESTS + NUMERICAL SIMULATION = RELIABLE RESULTS + TIME SAVINGS + COST SAVINGS

Numerous studies carried out by our experts

Our engineers and scientists, who are specialised in shock phenomena, have carried out studies for major research programs initiated by ESA and CNES. These include studies on the vulnerability of pressurised gas tanks and the impact resistance on Earth of a space capsule returning from Mars. We are proud to put our knowledge at the service of research and innovation.

THIOT INGENIERIE: 30 YEARS OF EXPERIENCE IN SHOCK PHYSICS

The only laboratory of its kind

Our laboratory, inaugurated in 2008, is the first private institution to specialize in shock physics and fast dynamics. The unique technology of our gas guns allows us to achieve higher impact velocities than anyone else. Our 2500 m2 laboratory and our test facilities have been ergonomically designed so that your test campaigns may be carried out as swiftly as possible and rapidly reconfigured to meet your most specific requirements.

WE ARE HERE TO SUPPORT YOU, WHETHER YOU REQUIRE OUR GLOBAL EXPERTISE
OR A SPECIFIC SERVICE

Cutting-edge metrology equipment

To obtain the most accurate data possible, we instrument your test setup with the very best metrology tools: high-speed cameras, VH, interferometry equipment, speed-measurement systems, strain and acceleration gauges, X-ray equipment… Nothing escapes our attention!

Did you know?

Space debris consists of waste from space exploration and includes disused satellites, spent launcher stages, parts that have become detached due to wear and various objects that the very first astronauts simply tossed “overboard”.

The first accident in orbit caused by space debris resulting from human activity was recorded in 1996. It involved a French military satellite, Cerise, which was struck by a piece of debris from the Ariane 1 rocket, launched 10 years previously.

17,000 objects the size of an orange or larger are currently in orbit around the Earth and are being continuously monitored by the various space centres in order to avoid a collision with the space station. However, smaller debris, of which there is much more, is impossible to track.
