Fluidic vectoring for exhaust nozzle

摘要

The invention relates to a method of directing an exhaust gas path and to an exhaust nozzle assembly for jet engines. The exhaust nozzle assembly (22) provides fluidic thrust vectoring of the primary stream (20) to enhance aircraft manoeuvrability. The exhaust nozzle assembly (22) includes a cooling air passage (40) that supplies cooling air (44). A vector opening (30) injects cooling airflow into the exhaust passage (24) to the primary stream (20). A cover plate (32) is movable to partially block the vector openings (30) and adjust the location of injection of the cooling airflow (44) into the exhaust passage (24).
