ABSTRACT:
A cargo barrier net (10) for retaining cargo within an aircraft fuselage in the event of a hard landing, crash landing, or in-flight turbulence is provided having a net structure made from Kevlar.RTM. or other materials having a high strength-to-weight ratio and end loops (20) made from straps of nylon or other materials having the ability to elongate and distend under an applied load. The end loops (20) attach the net structure to the tie-down frame within the aircraft's cargo compartment and, in the event of a hard landing or in-flight turbulence, the end loops (20) function to absorb forces placed upon the cargo barrier net (10) by elongating and distending under the shifting load. The cargo barrier net (10) also provides the advantage of being light weight due to the ability to use light weight, high strength materials such as Kevlar.RTM. for the net structure without compromising the needed ability for the cargo barrier net (10) to react to and compensate for shifting forces exerted upon the cargo barrier net (10) as cargo is jostled around during flight or landing.
