The purpose of the Rocket Engine Test Facility was to test full-scale liquid hydrogen

Liquid hydrogen

Liquid hydrogen is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form.To exist as a liquid, H2 must be pressurized above and cooled below hydrogen's Critical point. However, for hydrogen to be in a full liquid state without boiling off, it needs to be...

Capabilities

It consisted of two major buildings and several support service buildings. Test Stand A was designed for sea-level testing of vertically mounted rocket engines that exhaust into an exhaust gas scrubber and muffler. The A stand had the capability of testing engines with chamber pressures up to 4300 psia and thrust levels up to 50,000 pounds.

Test Stand B was designed by Anthony Fortini and Vearl N. Huff in 1959, but it was not built until after 1980. It could test horizontally mounted rocket engines exhausting into an exhaust diffuser, cooler, and a nitrogen-driven two-stage ejector system. The B stand, for altitude testing in a space environment, had the capability of testing engines with chamber pressures up to 1000 psia and thrust levels up to 1500 pounds.

The support systems included storage dewars for cryogenic fuels and a large water reservoir. Smaller buildings included a block house for observation, a pump house, a helium compressor shelter, and a liquid hydrogen pump vaporizer shelter. In 1984 the facility was modified to provide the capability for testing extremely large area ratio nozzles (to 1000:1).
