The report covers an investigation of three cargo restraint concepts: (1) an extensible-net-type restraint (such as a nylon net) secured directly to the airframe, (2) the same extensible net attached to load limiters (attenuators), and (3) an inextensible-net-type restraint (such as a steel net) attached to load limiters. Each concept was investigated analytically using computer simulation to determine the dynamic performance of the system under the action of crash acceleration pulses. Drop tests were also conducted to verify analyses. General comparisons were made to obtain the advantages and shortcomings of each restraint concept as well as the influence of controllable parameters. A substudy of the nature of the probable crash induced acceleration pulse was also undertaken. This led to a proposed standard pulse for cargo restraint design purposes. (Author)
