Abstract
A simplified actuation system for positioning the divergent flaps of a vectorable two-dimensional exhaust nozzle is disclosed. The system includes lever arms having cam surfaces pivotably attached to diverent flap crank shafts. An actuator is pinned to the nozzle sidewall and operably connected to a slider bar which has two cam followers at either end which are fixed with respect to each other and enage the cam surfaces of the lever arms. The slider bar is slideably engaged to the nozzle sidewall so as to permit radial movement with respect to the nozzle centerline. As the convergent flaps are moved the lever arms are translated axially and the cam followers in cooperation with the cam surfaces on the lever arms schedule the relative angle between the divergent flaps and thereby the exit area of the nozzle. Vectoring is provided operating the actuators which translate the cam followers in the radial direction, up or down, thereby rotating the divergent flaps so that they are pitched up or down in unison.
