bypass engine
Aviation; Aeronautics
A gas turbine engine in which a portion of the air moved by the first stages of the compressor bypasses the combustion chambers of the engine and mixes with the hot gases in the tail pipe. A turbofan ...
compressor stall-margin curve
Aviation; Aeronautics
A gas turbine engine operating curve which shows the relationship between the compression ratio of the engine and the mass airflow that must be maintained through the engine.
hybrid compressor engine
Aviation; Aeronautics
A gas turbine engine that has both centrifugal and axial-flow compressors.
single-spool turbine engine

EPR rated engine
Aviation; Aeronautics
A gas turbine engine whose rated thrust is expressed in terms related to its engine pressure ratio (EPR).
speed-rated engine
Aviation; Aeronautics
A gas turbine engine whose rated thrust is produced at a specified RPM.
low-pressure oxygen system
Aviation; Aeronautics
