Abstract
A divergent flap actuation system for a two-dimensional exhaust nozzle for a gas turbine engine powered aircraft includes stationary sidewalls (2) and (3) with oppositely disposed movable divergent flaps (10) and (39) located therebetween, and flush mounted rotatable divergent disks (22) and (49) with drive pins (21) and (48) attached thereto for engaging the flaps. Each divergent disk utilizes an individual actuator to provide independent movement of the rearward edges of the flaps in response to disk rotation. Utilizing flush mounted disks for controlling the position of the rearward edges of the opposed flaps minimizes sidewall thickness and allows use of full length, tapered sidewalls to minimize drag and nozzle weight while maximizing flexibility in thrust control.
