5.0-INCH (SERIES) LAUNCHERS

in the RIPPLE fire position, the intervalometer converts the firing pulse into a ripple pulse and successively fires all rockets at 95-millisecond intervals. Ripple firing operates the same on all pods. The intervalometer used with the 2.75-inch pod has a shaft that extends through the aft bulkhead of the launcher and a knurled knob with a reference (index) mark mounted on the shaft. Intervalometer switch positions are marked on the aft bulkhead of the center section. The intervalometer should NOT be manually rotated through the numbered positions except when checking an empty pod. Intervalometers used in the LAU-10 (series) pods cannot be manually rotated. When the intervalometer has made a complete four-round firing cycle, it automatically homes in on the original starting point (zero) and does not recycle without first de-energizing the circuit, and then re-energizing it. 5.0-INCH (SERIES) LAUNCHERS The LAU-10 (series) launchers are reusable launchers intended for shipping (without warheads), stowing, and firing four 5.0-inch rockets. When loaded with four completely assembled rounds, the total weight varies with rocket configuration from 500 to 550 pounds. The rockets are retained in the launcher tubes during shipping, handling, and flight by engagement of a spring-loaded detent pawl in the rocket detent groove 2-17 Figure 2-17.—Rocket launcher airborne configurations.
