Electric Arc Shock Tube (EAST)

Published by data.nasa.gov | National Aeronautics and Space Administration | Metadata Last Checked: October 27, 2025 | Last Modified: 2025-03-31
The Ames Electric Arc Shock Tube (EAST) Facility is the only shock tube in the U.S. capable of simulating shock-heated gas environments at the very high enthalpies encountered by atmospheric entry vehicles. The facility generates conditions for measurements of spectrally resolved radiance and kinetics of shock-heated gases from the vacuum ultraviolet through mid-infrared. The EAST program provides ground-based hyperthermal and hypervelocity environments in support of the nation’s research and development activities in thermal protection materials, aerothermodynamics, vehicle structures, and hypersonic propulsion and flight.
