Air-Mobility Rigid Shelter Systems.

摘要

This interim report covers the first portion of a long-range investigation dealing with the design and durability of lightweight,rigid structures (shelters) used by the military as combination shipping containers and housing for tactical and life-support services. This report covers the results of field and laboratory studies intended to correlate functional and structural problems with in-service conditions. It was found that water leakage into the shelters and into the sandwich panels was probably the basic problem area although many shelters appeared to have been defective at the time of delivery. It was found that,under adverse conditions, a polyamid paper honeycomb core would be significantly better for the sandwich panels than is the draft paper core now used. Major delaminations of the sandwich panels could not be correlated with impact damage such as would be caused by forklift bumps.
