BOMB SHACKLES

LEARNING OBJECTIVE: Identify the purpose and use of bomb shackles.

The Mk 8 Mod 5 bomb shackle is used on helicopters, such as the SH-3. The Mk 8 Mod 5 bomb shackle (fig. 10-31) is used to suspend and release a mine or torpedo that weighs from a minimum of 100 pounds to a maximum of 1,500 pounds. The bomb shackle incorporates suspension hooks spaced 14 inches apart, center to center. It has no integral

provisions for electrical release, electrical arming, or mechanical arming. However, the shackle can be electrically released if you attach an electrical release unit, such as the Aero 7B-1, to the shackle structure. The shackle can be mechanically armed if you attach arming solenoids to the shackle or to the structure on which the shackle is mounted.

The frame of the Mk 8 Mod 5 bomb shackle is an inverted U-shaped member. The frame suspension lugs are also U-shaped. They are attached to the ends of the frame by pivot bolts, which retain the hook link assembly in place within the frame. Inspection holes are located in the frame above each suspension hook so you can visually inspect individual hook latchings. There is also a hole in the frame so you can insert a safety pin that mechanically blocks the linkage to prevent the hooks from releasing. Other components of the Mk 8 Mod 5 bomb shackle are the cocking lever, release lever, latching lever, and associated springs.

When you cock the Mk 8 Mod 5 bomb shackle, you move the cocking lever aft until the latching block on the link assembly engages in the slot of the latching lever. The roller on the latching lever rides up and seats on the top of the release lever cam. When the release lever is moved forward, either electrically by the attached release unit or manually, the latching lever moves down and away from the latching block. This action allows the hook-opening spring and the weight of the store to move the hook link assembly forward, releasing the hooks.

Keep the Mk 8 Mod 5 bomb shackle in the released position except when it is actually carrying stores. The shackle is designed to operate without lubrication. Maintenance is limited to cleaning the assembly with dry-cleaning solvent (P-D-680), inspecting the components for wear and operation, and replacing the shackle.

DISPENSERS AND EJECTORS

LEARNING OBJECTIVE: Identify the purpose and use of dispensers and ejectors.

Dispensers and ejectors are used during tactical situations to provide additional offensive and defensive capabilities to the aircraft. These units are usually detachable. They are suspended from other installed suspension equipment, or they are mounted directly to the aircraft. They are used to suspend and release ordnance items, such as aircraft parachute flares and sonobuoys. In this section of the TRAMAN, you will learn about the basic characteristics of dispensers and ejectors currently in use.
