The Variable-Cycle TFE731 Turbofan Engine utilized in the altitude performance test is the same engine that was used in the Phase III sea-level test program. The engine description is presented in 3.1.1. The test engine, Part 3069600, Serial No. 7399, Build 2, was assembled with new hardware and instrumentation as required, and incorporated variable primary and fan exhaust nozzles. The variable compressor stator and LP turbine stator actuation systems were identical with those used during the Phase III test program.
