GUIDED MISSILE LAUNCHERS
purpose and use of guided missile launchers.
Identify the components of the LAU-7/A
(series) guided missile launcher.
Guided missile launchers provide the mechanical
and electrical means of suspending and air-launching a
guided missile from an aircraft. Because the physical,
mechanical, and functional requirements vary for each
particular missile-to-aircraft configuration (table 3-2),
a brief description of each type of missile launcher is
discussed in the following paragraphs.
LAU-7/A (SERIES) GUIDED MISSILE
The LAU-7/A (series) guided missile launcher (fig.
3-17) is a reusable launcher that provides a complete
launching system for use with the AIM-9 Sidewinder
(series) missiles. The launcher (fig. 3-17) has four
major assembliesthe housing assembly, nitrogen
receiver assembly, mechanism assembly, and power
The housing assembly is the main structural
member of the launcher. It is an extruded, machined
aluminum member that provides structural rigidity to
the launcher and includes provisions for mounting all
other assemblies. It also includes provisions for
mounting the launcher to the aircraft.
Nitrogen Receiver Assembly
high-pressure nitrogen (3,200 psig) used to cool the
missile's IR detector in the guidance system. Two
nitrogen receiver assemblies are available for use with
the launcher. One is a cylindrical fiber glass container
with a corrosion-resistant metal liner, and the other is a
plain cylindrical steel container. The receiver mounts in
the aft section of the housing assembly and screws into
the aft end of the mechanism assembly. All receivers
contain a charging valve (for refilling), relief valve, and
a pressure indicator mounted in the aft end of the
cylinder. The pressure indicator is color coded to ensure
correct readings as follows:
0 to 2.2 psi
2.2 to 2.8 psi
2.8 to 3.5 psi
3.5 to 5 psi
All readings listed must be multiplied by 1,000 psi.
