a. General. Parachute ejectors forcibly remove a personnel reserve parachute from its pack. Figure 13-4 shows a representative ejector, which contains two cartridges. Another type contains only one cartridge. In basic makeup, the ejector is a long, slender piston-cylinder assembly. Gas pressure is supplied by one or two cartridges contained in chambers called initiators. When the ejector is fired, the piston remains in the cylinder. The whole device remains gas tight.
b. Ignition Method. Ignition is by a springloaded firing pin striking a percussion primer in the cartridge. The firing pin is both cocked and released when the firing pin ring is pulled.
