초록

A gas turbine engine includes a flow control mechanism operable to direct at least a portion of a fan airflow from a secondary flow path into a core flow path.

대표
청구항

1. A gas turbine engine comprising: a high spool along an engine axis, said high spool operable to communicate a core airflow through a core flow path;a fan section operable to communicate a fan airflow into a secondary flow path and said core flow path;a low spool along said engine axis to drive said fan section;a starter/generator connected to said low spool, said starter/generator having a start mode in which the starter/generator rotationally drives said low spool and a generate mode in which said low spool drives said starter/generator to produce el...
