FALCON USER’S GUIDE MASS PROPERTIES Figure 3-1: SpaceX payload attach fitting The payload attach fitting (PAF) converts the diameter of the launch vehicle to a (typical) standard 1575-mm (62.01 in.) bolted interface (Figure 3-1). Payloads should comply with the mass properties limitations given in Figure 3-2. Payloads in excess of the figure can be accommodated as a mission unique service. Payload mass properties should be assessed for all items forward of the payload attach fitting 1575-mm (62.01 in.) bolted interface (Section 5.1.1), including any mission-unique payload adapters and separation systems. Mass property capabilities may be further constrained by mission-unique payload adapters, dispensers or separation systems. SpaceX can also provide a payload attach fitting with a wider interface.
