AEDC/UTSI J85 Turbojet Test Stands

摘要

Over the past seven years, the instrumentation and diagnostics team at the Arnold Engineering Development Center (AEDC), with cooperation from University of Tennessee Space Institute (UTSI) personnel, have 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 J8S-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 paper presents the test stand capabilities and a cross section of the test efforts accomplished to date. A second test stand, the J85 Full Annular Afterburner Rig, is currently nearing completion at the test site and is also discussed in this paper.
