What kind of structure is needed to support the enclosure system?

This depends on the total energy of the projectile and the use of the system dictated by the specific application. Our systems do not actually require the use of a structure. Blankets can be draped over or wrapped around the component being tested and connected back to themselves. For applications that require a curtain configuration, many times the curtains can be affixed to existing structure. In applications where a fairly large curtain system is being used to mitigate a small projectile, the weight of the curtain will absorb the energy. It simply needs is to be hung in place and we can provide modular, light weight truss systems for such applications. For high energy projectiles, we can engineer and design a structure according to the maximum loads at the anchor points.
