NASA Marshall engineers have unveiled an innovative, 11-inch hybrid engine testbed that promises low-cost, quick-turnaround testing solutions for advanced rocket motor hardware, component materials, and propellants.

“It’s time consuming and costly to put a new solid rocket motor through its paces – identifying how materials perform in extreme temperatures and under severe structural and dynamic loads,” said Benjamin Davis, branch chief of the Solid Propulsion and Pyrotechnic Devices Branch of Marshall’s Engineering Directorate. “In today’s fast-paced, competitive environment, we wanted to find a way to condense that schedule. The hybrid testbed offers an exciting, low-cost solution.
“That quicker pace can reduce test time from months to weeks or days,” said Precious Mitchell, solid propulsion design lead for the project.
