Preliminary results from the Superfluid On-Orbit Transfer (SHOOT) Flig
ht Demonstration which flew on Space Shuttle STS-57 in June 1993 are p
resented. SHOOT demonstrated the technology required to transfer super
fluid helium between Dewars in low gravity. In addition a number of co
mponents developed for SHOOT were flight proven and are now available
for use on other payloads. Included in this paper are a description of
the transfer process, the transfer rates and losses, observations of
the differences between ground transfers and those done on-orbit, and
the performance of a number of components. Among these components are
liquid acquisition devices, phase separators, liquid/vapour discrimina
tors, thermomechanical pumps, three types of valves, venturi flow mete
rs and a heat pulse mass gauging system.
