Primary Adhesively Bonded Structure Technology (PABST). Phase 1b. Preliminary Design
Abstract
An extensive structural design concept formulation and evaluation effort was conducted culminating in the selection of three concepts which offered the greatest potential for acquisition cost, maintenance cost, and weight reduction from the baseline structure. From these three concepts, the design selected for continuation into Phase II, Detailed Design, was a combination close-spaced/wide-spaced, internal/external skin stringer design. Iterative analysis and design support by extensive environmental coupon and component testing constituted the balance of the preliminary design effort of Phase Ib. Two surface preparations were investigated and resulted in selection of phosphoric anodize. An immersion tank FPL etch was the reference standard. The adhesive systems considered were the new environmental resistant 250 F cure, modified epoxy adhesive and their respective primers.
