Abstract
Abstract Means for supporting and joining flexible multi-sided structural panels in radomes and the like. The panels are each provided with flexible peripherally located flaps which are reinforced by stiffening members. The panels are applied to frames made up of interconnected rigid struts, with the flaps and their respective stiffening members overlapping the struts. The frames are interconnected by means extending laterally through joints including as sandwiched elements two peripheral flaps in face-toface contact, the stiffening members reinforcing said flaps, and a strut on each of the frames being interconnected.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
In a structure having an exterior surface defined by a plurality of flexible panels, means for supporting and joining said panels comprising in combination: a. flexible flaps which are integral with the edges of said panels, b. elongated stiffening members overlapped by said flaps, said stiffening members being immovable laterally relative to said flaps, c. frames underlying each of said panels, each said frames being made up of a plurality of interconnected rigid struts, and d. means for joining said panels and said frames along joints adjacent to the edges of said panels, said means extending laterally through the following sandwiched elements;
Claim 2
