A3.
The two types of impact firing fuzes are the
point detonating and base detonating types.
A4.
Upon arming, the mechanical timer starts,
and after a set time, the mechanical time fuze
initiates the firing train.
A5.
In
acceleration-deceleration
fuzes,
deceleration causes the fuze to function.
A6.
Proximity fuzes sense, usually by electronic
means, the presence and distance of a target.
AIRCRAFT ROCKET LAUNCHERS
LEARNING OBJECTIVE:
Recognize
the
shipping configuration for aircraft rocket
launchers and identify common aircraft rocket
launcher components.
Aircraft rocket launchers (pods) carry and provide
a platform to fire rockets. Launcher design permits
multiple loading and launching of 2.75-inch and
5.0-inch rockets. Rocket pods let rocket motors (and, in
some cases, completely assembled rounds) stay in the
same container from their manufacture, through
stowage, to their final firing.
Aircraft rocket launchers are classified as either
2.75-inch or 5.0-inch. They may be further classified as
either reusable or nonreusable. Launcher tubes that are
constructed of metal are considered reusable and are
usually
returned
for
reloading.
Under
certain
conditions, they may be jettisoned at the pilot's
discretion.
The 2.75-inch rocket launchers currently in use are
the LAU-61C/A and LAU-68D/A. Characteristics and
specifications for these launchers are listed in table 2-4.
For detailed information about the LAU-61 and
LAU-68 series launchers, refer to Aircraft Rocket
Systems 2.75-inch and 5.0-inch NAVAIR 11-75A-92.
The 5.0-inch rocket launchers are the LAU-10B/A,
LAU-10C/A, and the LAU-10D/A. Characteristics and
specifications for these launchers are listed in table 2-5.
For detailed information on the LAU-10 series
launchers, you should refer to Aircraft Rocket Systems
2.75-inch and 5.0-inch NAVAIR 11-75A-92.
SHIPPING CONFIGURATION
The rocket launcher-shipping configuration shown
in figure 2-16 is typical of all launcher-shipping
configurations, except for the RF barriers.
Center Section
The launcher center section is a cylindrical
construction of 4, 7, or 19 tubes held together by a
supporting framework, and it is covered with an
aluminum skin. The center section houses or supports
all other components of the launcher.
