摘要

An adaptive gas turbine engine (676) is disclosed having a convertible fan system (640) adapted to have a variable fan pressure ratio while the air flow into the convertible fan system (640) remains substantially constant and an adaptive core (678) having a compressor (679) capable of maintaining a substantially constant core pressure ratio while a core airflow flow rate is varied.
