Gyro
Installation
Details
.
Important
dimensional
and
load
information
is
given
in
this
drawing
that
will
impact
the
design
details
of
the
structure
that
will
receive
the
gyro
as
well
as
selection
of
adhesive
to
bond
the
gyro
into
the
hull.
The
foundation
“saddles”
of
the
gyro
are
designed
to
be
bonded
directly
to
the
composite
hull
structure
of
the
vessel
to
effectively
distribute
gyroscopic
loads.
Note
that
any
paint
or
gel
‐
coat
present
in
bond
area
should
be
removed
so
that
adhesive
will
bond
directly
to
laminate
fibers
and
resin.
A
complete
bond
is
required
between
the
inside
surface
of
the
saddles
and
the
hull
structure.
To
aid
in
determining
the
quantity
of
adhesive
required,
the
surface
area
of
Port
saddle
bond
area
is
340
in
2
(2194
cm
2
).
The
starboard
saddle
bond
area
is
310
in
2
(2002
cm
2
).
Seakeeper
has
an
optional
installation
fixture
available,
P/N
90012,
that
is
intended
to
duplicate
the
gyro
foundation
geometry
in
order
to
check
clearances
and
alignment.
The
fixture
will
allow
the
builder
/
installer
to
lay
‐
up
and
adjust
the
foundation
dimensions
to
create
a
low
‐
clearance
fit
between
the
gyro
foundation
saddles
and
the
hull
structure.
Shear
strength
of
the
adhesive
will
be
maximized
if
the
cured
thickness
between
the
vessel
structure
and
gyro
saddles
is
at
the
thinner
end
of
the
adhesive
manufacturers
recommended
range.
Therefore,
the
fixture
should
be
used
to
confirm
that
the
overall
dimensions
of
the
foundations
are
square
and
level
and
that
the
adhesive
gap
is
within
the
adhesive
manufacturer’s
maximum
recommended
thickness
‐
see
Figure
5.
The
hull
structure
supporting
the
gyro
should
be
installed
so
the
gyro
is
parallel
to
the
water
‐
plane
in
the
port/starboard
and
forward/aft
directions.
Note:
Do
NOT
use
the
installation
fixture
to
establish
gyro
envelope
dimensions.
Refer
to
Drawing
No.
90219
for
envelope
dimensions.
