Abstract
A swaybrace system includes one or more pairs of opposing swaybrace arms that pivot in relation to aircraft structure, each arm with a pad thereon automatically being biased by a spring-loaded wedge or the like to cause the pad to contact with the store under all load conditions. Each arm in one embodiment is bifurcated into upper and lower portions capable of flexing, the store-contacting pad being attached to the lower portion, with the lower portion flexing with respect to the upper portion through a predetermined distance Sa for pad loads between zero and a predetermined pre-load. The upper portion, together with the lower portion and pad, flexes about the wedge through a predetermined distance Sb for pad loads between the predetermined pre-load and a predetermined maximum load. An alternate embodiment utilizes resilient means between the pad and arm to allow the pad to move through the predetermined distance Sa with respect to the arm, the arm together with the pad flexing about the wedge through the predetermined distance Sb, all under corresponding load conditions. Distance Sa equals distance SB in each embodiment. Each embodiment automatically loads itself to obtain adequat…
