bypass engine

A type of gas turbine engine in which a portion of compressor air is bypassed around the combustion chamber and into the tailpipe. A bypass engine permits a higher combustion temperature than in a pure jet engine, with consequent improved efficiency in terms of higher thrust and low specific fuel consumption.
