- Abstract
PAF-3284S is the Payload Attachment Fitting of H-IIB Launch Vehicle for H-II Transfer Vehicle (HTV). This paper describes the outline of PAF-3284S development and verification test. HTV is larger and heavier payloads for Japanese launch vehicle than conventional payloads. Therefore, PAF-3284S structure must be designed to accommodate the HTV unique specification and interface condition. The structure of PAF-3284S is semi-monocoque structure similar to HTV structure. The validity of structural design had been verified by analytic study, structural strength test and HTV/PAF separation test. In the structural strength test, not only the main structural strength but also the behavior of HTV/PAF-3284S interface plane is examined. Every test had been finished successfully and the results were similar to the analytic study. PAF-3284S with HTV will be assembled into H-IIB Launch Vehicle and launched in September, 2009.
