Abstract

A wind-mounted gas turbofan engine 10 is provided with a bypass exhaust system that reduces airflow drag during subsonic aircraft flight operation by first, inwardly curving the exhaust system exit 28 to turn the bypass flow away from the airplane wing; second, by predetermining the location of a nozzle throat within the bypass stream to control exit exhaust pressure so as to match outside air pressure and third, by decreasing the diameter of a portion of the engine core casing 18 just downstream of the bypass exhaust stream exit referenced at 29 in phantom. <IMAGE>
