AS has often been iterated, the Harrier is a close support fighter with the facility for extremely short, or even zero, ground take-off runs. This facility is achieved by directing the jet efflux of the Rolls-Royce (Bristol Engine Division) Pegasus engine out of four rotating nozzles moving in symmetry, these rotating nozzles vectoring the engine thrust over 98½ deg. of movement from aft to forward of the vertical. The nozzles are rotated by shafting and chains, powered by an air motor, and controlled by a single lever in the cockpit. The complete system is termed the Engine Nozzle Actuation System, and pilot selection and air motor output comprise the input and error signals of a simple servo loop controlling engine nozzle position (Fig. 1).
