unlike those encountered in developing ARE
pumps, but they will be magnified by the higher
capacity requirements, by the resulting higher
power requirements, and by a number of special
restrictions imposed because of the proposed
locations of the pumps.
The location of the fuel pumps imposes problems
in impeller and in inlet and discharge housing
design, since it will be necessary to match the
fluid dynamic requirements of passages leading
from heat exchangers into the pumps and from the
pump discharge housings into the core. Various
impeller designs are being investigated and will
be used to evaluate cavitation characteristics.
Previous experience with ARE impellers indicates
that casting is not a promising means for fabri-
cating lnconel impellers in the present state of
the art, and therefore a brass impeller has been
made for studying fabrication problems and' ob-
taining initial performance data. Preliminary
planning has been started for the fabrication of
44
models for study of pump discharge and entry
conditions.
Seal design, bearing structure, cooling, lubri-
cating, and driving means are other problems being
studied, and the reliability of these components
and operations is being ascertained through a
succession of mechanical shakedown, water per-
formance, and high-temperature tests.
