The HITF was founded in 1980 with a mandate to study the
hypervelocity impact (HVI) characteristics of composite materials such as
graphite epoxy. A small, 1.7 mm bore, light-gas gun was built in-house from
drawings supplied by the NASA Langley Research Center. A few years later, a 4.3
mm bore light-gas gun was purchased from a commercial vendor. It was then
modified and improved to perform meteoroid and orbital debris shielding
research. Later, the HITF added a 12.7 mm bore gun, which was provided by the
NASA Ames Research Center Hypervelocity Free-Flight Facility.
Since its inception, the HITF has performed
and analyzed over 8000 hypervelocity impact experiments on spacecraft
shields and materials. These experiments and the ensuing analysis, in
combinations with countless hydrocode simulations, have contributed to
the development of shield ballistic limit equations used as the foundation
for thousands of meteoroid and orbital debris threat assessments in support of
critical space programs.
