 "Additionally, in the space between the bumper sheet and the containment wall, the particle fragment cloud expands to impact a larger surface area of the containment wall, thereby eliminating concentrated energetic impact of the fragments on a single point on the wall, and increasing the penetration resistance of the wall."

"In existing structures such as a space station, the structural design is quite intricate with many interrelated "trade-off" of parameters and the existing designs have a "Whipple Shield" for the crew area which is designed to provide protection against hypervelocity impact matter. With increasing concerns regarding protection against the accumulating orbital debris in space and its size, it is desirable to enhance the protection capability of existing Whipple Shields without requiring expensive redesign or without significantly increasing weight."

"SUMMARY OF THE INVENTION

The present invention is a system for enhancing the protection capabilities of existing Whipple Shield structures against penetration by hypervelocity impact particles and for enabling greater protection capabilities for new Whipple Shield structures against penetration by hypervelocity impact matter at reduced structural weight and/or stand off (spacing) distances. "
