tiles/SRB's
In October, production will being on about 3000 new tiles to
be used on the third shuttle, the Discoverer. The new tiles,
a mix of silica and aluminoborosilicate fibers as opposed to
the present all silica ones, will provide a ``tougher external
skin'' for the Discoverer and greater heat resistance. They
will cover about 10% of the Discoverer and possibly more of
future shuttles. Lighter than the present ones, they will
lessen the weight of the Discoverer by about 1000 pounds.
Delivery to Rockwell for installation should be in January
of 1982.
A plant for the refurbishing of the solid rocket fuel boosters,
a reusable part of the shuttle, may be built near Cape Canaveral
for the sole purpose of repairing any damages the SRB's sustain
during lift off.
