A gas turbine engine assembly with a variable area nozzle and a method of controlling this nozzle

摘要

A gas turbine engine system includes a first nozzle section (40a) associated with a gas turbine engine bypass passage (32) and a second nozzle section (40b) that includes a plurality of positions relative to the first nozzle section (40a). In at least one of the positions, there is a gap (64) between the first nozzle section (40a) and the second nozzle section (40b). A movable door (52) between the first nozzle section (40a) and the second nozzle section (40b) selectively opens or closes the gap (64).
