Hush house hosts F135 firing for JSF

The first F135 engine for the F-35 Joint Strike Fighter recently completed successful test runs at the Naval Air Station Joint Reserve Base facility in Fort Worth, Texas.

The trials took place at an indoor engine test facility that was modified to handle the 40,000lb of thrust produced by the F135. The Naval Air Station Joint Reserve Base (JRB) at Carswell is adjacent to Lockheed Martin's Fort Worth manufacturing facility where the F-35 JSF is being assembled and validated.

The JRB's aircraft engine ground-test facility — dubbed the Hush House — was built in 2001 for F-18 engine tests.

Pratt & Whitney worked with the JRB to modify the facility's test equipment and sound-damping structures to support the high thrust produced by the F135 engine. To validate the facility's ability to host F135 engine tests, the first test engine was run to maximum thrust and full afterburner.
