Highlighting a NASA Facility That Provides Function Beyond Space Exploration

Propulsion Systems Laboratory (PSL)

An engine is being set up for testing in the Propulsion Systems Laboratory at Glenn Research Center.

The Propulsion Systems Laboratory at Glenn Research Center is NASA’s only ground-based test facility that can provide true flight simulation for experimental research on air-breathing propulsion systems. The Propulsion Systems Laboratory (PSL) complex provides world-class test and evaluation capabilities in support of NASA’s research and testing mission and charter. Built in the early 1970’s, PSL has hosted a number of unique programs that have furthered engine research technologies.

Altitudes to 90,000 feet and Mach numbers to 3.0 in one cell and 6.0 in the other can be simulated continuously. Engine airflow is available to 480 lb/s at an inlet pressure of 55 psia or to 380 lb/s at 165 psia. Inlet temperature control also is available. Real-time display and post-test data reduction are available for all measured and calculated parameters.

The PSL is a highly versatile test facility developed to suit the one-of-a-kind testing common to NASA aeronautics research and testing programs. This versatility allows quick reaction to changes in program direction, as well as complete flexibility to pursue new goals that arise unexpectedly from ongoing experimental research.

Unique concepts in altitude engine testing have been pioneered and perfected in the PSL, such as multiaxis thrust measurement, vectored and reverse exhaust gas collection, infrared imaging at altitude, aeroelastic measurements, transient pressure and/or temperature distortion simulation and flight transient simulation. Recognizing innovation, other test organizations have asked to share PSL’s expertise.

The Propulsion Systems Laboratory at Glenn Research Center is being utilized to test a PF405 engine.

To initiate using the PSL at NASA Glenn, interested parties should complete and submit a test request form available online at http://facilities.grc.nasa.gov/psl/psl_test_request.html.

The form also is available in electronic format for offline submission.
