MND Engineering:
All terrain services
From studies on hazardous terrains and measurements in extreme conditions to laboratory trials and computer simulation, MND Engineering offers you a complete range of expertises for your projects.
Some projects:
> Development of the DaisyBell(®), new helicopter-borne avalanche release system, including experimental protocols, development tests under crane and in flight (measurements, data acquisition, analysis).
> Characterization of the aerial overpressure wave generated by the system Gazex ®
> OPALE project
(Works of protection and Suburban buildings subjected to the Action of avalanches)
– Coordinator: Cemagref (Grenoble-France)
– Financing: French National Agency for Research
> Impact of avalanches against a structure: development of specific experiments based on the inverse analysis of measured strains – experimental site of the Lautaret Pass (France)
> Evaluation of the natural risks along an international road: analysis of 5 major avalanche paths and protection proposals
> Structures subjected to natural hazards: numerical modelling of rock shed, rockfall nets or protection kit subjected to an impact.
