Bulkheads. Two internal vertical bulkheads shall be
3.5.5.2
installed on each life raft so as to divide the flotation tube into two
separate compartments, The bulkheads shall be constructed, located and
attached to the inside of the tubes as specified in the applicable
drawings.
Inflatable seat. Each life raft shall have an
3.5.5.3
inflatable seat fabricated from the laminated cloth conforming to MIL-C-
23070, variety C. The inflatable seat shall be circular and the ends
shall be tailored to fit the curvature of the inflatable tube. The
inflatable seat shall be an independent air chamber, prior to the instal-
lation onto the life raft, and shall be capable of being manually inflated
through the topping-off valve conforming to MS22054. The entire area of
contact between the ends of the seat and the flotation tube shall be
cemented together and reinforced as specified in Drawings 62A82H1 or
62A82H2, as applicable.
Inflation system.
3.5.6
Manual. The inflatable tube shall contain two
3.5.6.1
topping-off valves conforming to MS22054 for the manual inflation of the
life rafts. The topping-off valves shall be installed on the same side
of the life raft, one on each side of the bulkhead, in accordance with
Drawings 62A82H1 or 62A82H2, as applicable,
Carbon dioxide.
3.5.6.2
LRU-12/A and LRU-13/A rafts. The carbon dioxide
3.5.6.2.1
inflation system for the LRU-12/A and LRU-13/A rafts shall conform to
MIL-I-18369, Drawings 63A120H1, 62A82H1 and 62A82H2, as applicable.
LRU-1/P rafts. When the carbon dioxide inflation is
3.5.6.2.2
required by the acquisition (see 6.2.1m), the cylinder assembly of the
carbon dioxide inflation system for the LRU-1/P rafts shall conform to
Drawing 55C3689. The inlet manifold shall conform to MIL-I-18369 and
Drawing 63A120H1.
Location and attaching of the carbon dioxide inflation
3.5.6.2.3

to the rafts as in Drawings 62A82H1 and 62A82H2, as applicable. The
inlet manifold hose, when attached to the carbon dioxide cylinder valve,
shall not contain any bends or folds so that the entire length shall be
utilized.
Diffusion of the carbon dioxide entering the raft
3.5.6.2.4
inflatable tube chamber. The carbon dioxide entering the raft inflatable
tube chamber through the manifold shall be again diffused by a deflector
to lessen the accumulation of the solid carbon dioxide at the nearest
tube fold line. The deflector shall not interfere with the normal
operation of the life raft.
