Subscale Diffuser Testing, E-3 produces first steam

Phase 2 of the A-3 Test Facility Subscale Diffuser Risk Mitigation Project at Stennis Space Center reached a milestone Oct. 25 when the E-3 Test Facility produced superheated (500+ degrees) steam for approximately 3 seconds at more than 400 psi. The test team, led by Barry Robinson of NASA's Test Projects Office, followed that success with further tests to lengthen the duration of steam production. On Nov. 1, they were able to maintain a consistent pressure and temperature of steam for 60 seconds. In December, the team began Phase 3 of the testing, providing data for the design and procurement to build the full-scale version of the steam diffuser for SSC's A-3 Test Stand.
