(4) Sweatboard-to-sweatboard stowage.
(a) Basic principles
of sweatboard-to-sweatboard stowage
of 750-pound bombs areillustrated
in figure 9-60.
Notice the large void forward of the stanchion. Frequently, large voids occur that are only slightly smaller than the unit
load. As a result, a full-block structure like the one shown is required. Notice also that, at the ladder, a spacing structure
of the same dimensions as the end support of the encasement is used to increase the bearing surface for the adjacent
loads. Effectively, this structure is an extension of the encasement and aids in athwartship blocking of the entire row.
