Figure 10-33.—SUU-25F/A dispenser. rotate the shear latch over the tube opening and fasten it with a shear pin. Four breeches and breech caps and a spider assembly can be mounted on the forward bulkhead. During dispenser loading and unloading procedures, remove the breech caps and breeches to prevent air pressure buildup when inserting the flares. With the breech caps removed, flares can be pushed rearward during unloading (fig. 10-32, view A). A reusable nose fairing is installed prior to flight to provide protection to the spider assembly and reduce drag. When installed, the detent safety pin electrically safes the dispenser. During flight operations, the cartridge is fired by an electrical firing pulse routed from the aircraft to the breech of the dispenser. Gas pressure is metered into the forward end of one of the tubes. The expanding gas pressure from the cartridge exerts force against the two flares in the tube. When sufficient force is developed to shear the shear pin off the latch assembly, both flares are ejected into the airstream. The force of the airstream causes the drogue trays to separate from the flares, pulling the safety pins from the flare fuzes. Further separation pulls the flare lanyard to initiate the flare timing mechanism. After the cartridge fires, the dispenser intervalometer automatically steps to the next position and is ready for firing the next tube. Maintenance procedures for the dispenser are concerned with cleaning and inspecting. For further information about the SUU-44 dispenser, refer to SUU-44 Dispenser, NAVAIR 11-75AA-44.
