4.6.2. Powered Flight
The maximum fairing inside wall temperature will be maintained at less than 93 °C (200 °F), with an
emissivity of 0.92 in the region of the payload. However, the payload will see significantly lower
temperatures and emissivity due to fairing
acoustic blankets. This temperature limit
envelopes the maximum temperature of any
component inside the payload fairing with a view
factor to the payload.
The fairing peak vent rate is typically less than 1.0
psi/sec, as shown in Figure 4.6.2-1. Fairing
deployment will be initiated at a time in flight that
the maximum dynamic pressure is less than 0.01
psf or the maximum free molecular heating rate is
less than 1136 W/m
2
(0.1 BTU/ft2/sec), as
required by the payload.
