ADVANCED DISTRIBUTED ENGINE ARCHITECTURE-DESIGN ALTERNATIVE

摘要

A gas turbine engine (10) includes a first compressor (12) and a first turbine (14) for driving the first compressor (12). A core section (29) includes a second compressor (20) and a second turbine (24) for driving the second compressor (20). A third turbine (30) is arranged fluidly downstream of the first turbine (14) and the second turbine (24) and configured to drive a power take-off (32). A first duct system (38) is arranged fluidly between the first compressor (12) and the core section (29). The first duct system (38) is arranged to reverse fluid flow before entry into the core section (29).
