5.2.4.1. Payload Cone Interfaces
Several different payload cones can be provided to meet mission unique interface requirements. The
baseline Minotaur IV 38.81 in. payload interface is described in Section 5.2.3. However, Orbital has other
flight proven payload options. One option maintains the 986 mm (38.81 in.) interface, but increases the
amount of fairing volume by using a two piece payload cone that moves the interface approximately 203
mm (8 in.) aft. This option adds 9 kg to the LV. Orbital can also provide other options, such as 1194 mm
(47 in.) or 1575 mm (62 in.) interfaces required by some separation systems. These options are shown in
Table 5.2.4-1 with corresponding fairing envelopes shown in Figures 5.2.4.1-1 through 5.2.4.1-3.
5.2.4.2. Dual and Multi Payload Adapter Fittings
The Minotaur launch vehicle design flexibility and performance readily accommodates multiple spacecraft
that are independently deployed when required.
5.2.4.2.1. Dual-Payload Adapter Fitting
Provisions for larger multiple payloads exist for the Minotaur IV launch vehicle. A flight proven Dual
Payload Attach Fitting (DPAF) supports delivery of two primary spacecraft to orbit. The structure that
supports the dual payload configuration includes a 1600 mm (63 in.) diameter cylindrical section that is
configurable in height depending on payload unique requirements. In the DPAF configuration, the aft
positioned spacecraft mounts to a cone inside the cylinder which is in turn mounted to the forward flange
of the 62 in. payload adapter cone. The forward positioned spacecraft is then mounted to a cone on the
forward end of the DPAF cylinder using a 986 mm (38.81 in.) separation system. After the forward
