DARPA funds Reaction Engines hypersonic precooler tests

The precooler heat exchanger is a key component of the company's revolutionary SABRE air-breathing rocket engine and has the potential to enable other precooled propulsion systems. The primary HTX test objective is to validate precooler performance under the high-temperature airflow conditions expected during high-speed flights up to Mach 5.

"We have been greatly encouraged by the increasing interest in our technology's potential and are thrilled to embark on our first U.S. government contract with DARPA for HTX," said Dr. Adam Dissel, President of Reaction Engines Inc. "Full-temperature testing of the precooler will provide the most compelling near-term proof of the technology's potential to accelerate the future for high-speed air-breathing systems."

The HTX precooler test builds upon previous successful ground tests of the precooler technology conducted at ambient environmental conditions in the United Kingdom. These previous tests validated precooler design methodology, manufacturing techniques, and test operations plans.
