Frangible fairings (fig. 2-27) are made of an
impregnated molded fiber designed with a waffle- or
grenade-type structure that shatters readily upon rocket
impact or from a blast. The fairings fit flush with the
outside surface of the center section and form an
aerodynamically smooth joint. The forward fairing
consists of a one-piece molded section that disintegrates
on rocket impact.
The tail fairing for the LAU-10
(series) (fig. 2-27, view A) is molded in two sections
(nose and base), The rocket blast shatters the nose
portion. The base section remains on the launcher and
acts as a choke or funnel to direct debris away from the
aircraft. The tail fairings for the LAU-61 and LAU-68
(series) are distinctively different in appearance (fig.
2-27, view B). They are made of aluminum and are open
on both ends. They function in the same manner as the
base section of the tail fairing for the LAU-10 (series).
Fairings are not shipped with the rocket launcher
packages. They must be ordered separately and are
received in sets packaged in cylindrical-shaped
cardboard fairing containers (fig. 2-26).
Fairings are not used in all applications. You should
review the specific aircraft tactical manual for any
restrictions in their use.
A breaker switch is used on all rocket launchers.
The breaker switch is a safe-arm device that prevents
loaded rockets from firing. It is usually located on the
top of the center section of the launcher between the aft
end and the aft electrical receptacle. Figure 2-28 shows
the various safe-arm devices currently in use.
