摘要

Over the past 6 years, the instrumentation and diagnostics team at the Arnold Engineering Development Center, with cooperation from University of Tennessee Space Institute personnel, has utilized a sea-level-static turbine engine test stand for low-cost, flexible-schedule testing of developmental propulsion diagnostics systems, instrumentation, and measurement techniques. The test stand engine, a J85-GE-5 turbojet with afterburning capability, provides the necessary high-velocity, high-temperature exhaust gas (representative of larger augmented gas turbine engines) for diagnostics hardware demonstration and validation. This article presents the test stand capabilities and a cross-section of the test efforts accomplished to date. A second test stand, the J85 Full Annular Augmentor Rig, is currently under construction at the test site and is also discussed in this article.
