Figure 5.1.1.1-1. 50” Payload Fairing Dynamic Envelope with
38” (97 cm) Diameter Payload Interface
5.1.2. Optional 61” Payload Fairing
To fit payloads larger than those that can be accommodated by the standard 50” diameter fairing, a larger
61” diameter fairing is available as an enhancement. This structure uses an innovative diffusion-bonded
titanium sandwich panel composed of titanium facesheets and titanium honeycomb core. The 61”
diameter titanium fairing, along with its separation and deployment system, is qualified for flight and has
flown successfully on previous Minotaur I missions. Impacts to performance when compared to the 50”
fairing are negligible as a result of the more aerodynamic bi-conic nose.
5.1.2.1. Payload Dynamic Design Envelope (61” Payload Fairing)
Figure 5.1.2.1-1 shows the maximum dynamic envelopes available for the payload during powered flight
within the optional 61” payload fairing. The dynamic envelopes shown account for fairing and vehicle
structural deflections only. The payload contractor must take into account deflections due to spacecraft
design and manufacturing tolerance stack-up within the dynamic envelope. Proposed payload dynamic
envelope violations must be approved by Orbital via the ICD.
