####### EO-1 FMEA CRITICALITY CATEGORIES

The Severity Criticality codes for this FMEA are defined as follows:

1\) Effective loss of the mission (nonrecoverable complete loss of ALI
data).

2\) Loss of the Hyperion mission (nonrecoverable complete loss of
Hyperion science data).

3\) Serious degradation but still meets some of the Level I ALI and/or
Hyperion requirements.).

4)  Some degradation or operations impact, but still achieves the
    baseline mission.

5)  Little or no impact to mission success or mission operations.

Examples are:

Number 1 would include things such as the power system, WARP dying
completely, or a complete launch failure.

Number 2 would include the Hyperion failing by itself.

Number 3 would include a Hyperion ASP failure, or an X-band Phased Array
failure.

Number 4 would cover heaters.

Number 5 would include the PPT, GPS, AC, etc.

EO-1 FMEA ASSUMPTIONS

(ADAPTED FROM GSFC P-302-720 AND GSFC S-302-89-01)

-   Only one failure exists at a time.

-   All inputs (including software commands) to the item being analyzed
    are present and at nominal values.

-   All consumables are present in sufficient quantities.

-   Nominal power is available (except when the availability of power is
    part of the failure(s) being considered.

-   For this FMEA, only the launch vehicle mission unique elements are
    analyzed.

####### TREATMENT OF REDUNDANCY

Although EO-1 is by system design ground-rules a "single-string"
spacecraft, redundancy was included where practical, given programmatic
and technical constraints. In some cases, the redundancy is actual
multiple identical functions of which one is selected for use at any one
time. In other cases, the redundancy consists of different functions
that can provide more-or-less equivalent results; the second serving as
a secondary or backup to the primary. In still other cases, a function
may consist of a number of parallel channels of which one or more may
fail while still providing a usable but degraded result. This third
category is illustrated by the solar array strings, the 64 elements of
the X-Band Phased Array Antenna, or the multiple focal plane elements of
the ALI instrument.

In this FMEA, failure modes of functions with redundancy are identified
with an "R" modifier with the assigned failure Severity Category.
Without redundancy, the failure will have the Failure Effects indicated,
although in the "Remarks" there may be some work-arounds or other
compensations to mitigate some of the worst effects. However, such
mitigations would be very much a "last resort" and not intended as a
form of redundancy. With redundancy (an "R" modifier to the assigned
failure Severity Category), the Failure Effects indicated give the
results of the failure [as if there was NO redundancy
available]{.underline}. The redundancy that is available will be
described in the "Compensating Features/Action" portion of the "Remarks"
column. The application of the available redundancy negates the effect
of the actual failure and means that the indicated "Failure Effects" do
not occur. The original failure is the "one failure" upon which this
FMEA is predicated. If the redundant function were then to fail (a
second failure), the indicated "Failure Effects" would be observed
(excepting the third category mentioned in the above paragraph where
there are many parallel channels). In that case, multiple failures could
be tolerated -- a slow, hopefully graceful, degradation would occur.

####### EO-1 LAUNCH VEHICLE

The EO-1 will be launched on a standard Delta vehicle. It will be seen,
however, that the EO-1 launch requires a specific piece of mission
unique launch hardware and associated analyses. All launches of course
require certain mission unique analyses and mission unique orbit and
launch parameters. EO-1 is no different in that respect. For any launch
vehicle and any spacecraft, the mission analyses and the launch vehicle
itself are potentially catastrophic single-point failures. Given that
boiler-plate caveat, this FMEA is interested in any truly mission unique
elements that may be required for this specific Delta launch.

EO-1 is manifested with several other spacecraft as a multiple
deployment launch. There are two very small additional spacecraft that
are attached to the Delta at or below the base of the Payload Attach
Fitting (PAF) for this Delta. This PAF is a standard Delta PAF, totally
conventional and absolutely non-unique to this launch (except for the
usual mission-specific set of analyses). There is also an additional
major additional spacecraft on this launch - SAC-C. SAC-C is housed
within the one major piece of mission-unique equipment for this launch
-- the Dual Payload Attach Fitting (DPAF).

The DPAF is a cylindrical structure that attaches to the base of the
standard PAF and extends around and above the SAC-C, essentially
enclosing the SAC-C spacecraft. The SAC-C attaches at the payload attach
ring at the top of the standard PAF. The DPAF, extending above the
SAC-C, terminates in a payloads attach ring that is identical to that at
the top of the standard PAF. The EO-1 attaches at the payload attach
ring at the top of the DPAF. This configuration creates a launch stack
with EO-1 at the top and SAC-C within the DPAF. The standard PAF at the
top of the Delta supports both the SAC-C and the DPAF/EO-1 stack. The
other two small additional payloads don't enter into this discussion.

The use of a DPAF structure has become standard for various launch
vehicles -- however, not for Delta. Delta has never flown a DPAF. This
is the first DPAF mission for a Delta. The Delta DPAF is being
constructed by Matra Marconi, the DPAF provider for Ariane.

From the point of view of EO-1, the planned payload stack is a good
configuration, given that we are the first Delta launch to use a DPAF.
EO-1 is the top payload of the stack -- we are the first payload to be
deployed. Presumably if there is a DPAF failure, it would happen after
EO-1 is deployed.

The deployment sequence is roughly as follows:

1.  The standard Delta fairing is split off and dropped.

2.  EO-1 is deployed from the top of the DPAF.

3.  The now-empty DPAF is separated near its base from the DPAF attach
    station on the standard Delta PAF.

4.  The DPAF is discarded, thus exposing the SAC-C.

5.  The SAC-C is deployed from the top of the standard PAF.

The payload attach ring at the top of the standard PAF and the payload
attach ring at the top of the DPAF are identical. Both use a restrained
Marmon Clamp. Both of these Marmon Clamps are split halves with
bolt-joints at the clamp band ends on opposite sides of the vehicle. At
each joint, the clamp band ends are spaced about 3 inches apart, thus
requiring each bolt to be about that length. A pyro bolt cutter is
installed on each bolt shank (between the attach points at each clamp
band end). At ten equi-distant locations around the periphery of the
payload attach ring, restraining brackets are located. In each
restraining bracket is attached one end of a radial mounted spring; the
other end of the spring is attached to an immediately adjacent anchor on
the clamp band. Before payload deployment, the Marmon Clamp holds these
springs expanded. Cutting either bolt is sufficient to release the
entire clamp band. The springs then pull the clamp band away from the
payload attach ring and into the restraining brackets. A set of four
axial push-off springs then separate the payload from the PAF (and in
the process, separate several umbilical connectors also located at the
separation plane at the payload attach ring).

The DPAF body separates at a plane near the lower DPAF body attach
station adjacent to the base of the standard PAF. This separation joint
is a frangible band that is fractured along its circumference by an
explosively inflated expansion tube. This design is essentially
identical to that used on the DPAF units built by Matra-Marconi for the
Ariane. This assembly and its ordnance units and fire devices are fully
redundant with the exception of the expansion tube itself. However, that
is not an issue for EO-1.

The wiring harnesses for the pyros that separate EO-1 from the top of
the DPAF are brought up opposite sides of the DPAF. These harnesses each
pass through separate connectors located at the DPAF body separation
plane described immediately above. These connectors separate when the
DPAF body is separated; by that time, these harnesses have served their
purpose and EO-1 is long gone and on its way.

The EO-1 launch mission-uniques are the DPAF design and construction and
the additional analyses such as the coupled loads analysis for the EO-1,
DPAF, SAC-C, PAF, and Delta stack. The EO-1 deployment pyro harnesses
and connectors on the sides of the DPAF should also be considered
mission-unique.

Perhaps it should be noted here that the Delta fairing for the EO-1
mission suffered some damage during transport. That damage has been
repaired and KSC is monitoring the situation.
