Table 6-5. Spacecraft Acoustic Margins and Test Duration
Test Margin Duration, min
Qualification +3 dB over acceptance 2
Proto-qualification +3 dB over acceptance 1
Acceptance Maximum expected acoustic level 1
Shock qualification
The spacecraft should be compatible with the shock environment in section
5.5 with a 3-dB margin. The shock environment in section 5.5 represents
the maximum expected environment with no added margin. Analysis,
similarity, and/or test can demonstrate qualification.
Adapter matchmate
and fit-check
test
For the first mission of a spacecraft type, a matchmate test is required.
The test will be performed between the spacecraft and the adapter flight
hardware at the spacecraft manufacturing facility. This test will include
firing the spacecraft separation ordnance to define the shock transfer
function. Repeat missions will incorporate an adapter fit check at the start
of the processing flow at the Sea Launch processing facility. These tests
include both electrical and mechanical mates (see fig. 6-7).
