PARACHUTES
LEARNING OBJECTIVE: Identify the
types, characteristics, and basic operating
procedures for Navy parachutes.
A parachute consists of five major parts—the
harness, container, suspension lines, canopy, and pilot
chute (fig. 11-6). The harness is an arrangement of
nylon webbing and metal fittings. It is designed to hold
the parachute securely to the wearer and provide a seat
or sling during descent. The container encloses the pilot
chute, canopy, and suspension lines. The suspension
lines are made of nylon and join the canopy to the
harness. The canopy is a large round area of cloth that,
when inflated, slows the descent of a falling body. The
pilot chute is a small parachute attached to the top of the
canopy. When the ripcord is pulled, the pilot chute
deploys and helps deploy the main canopy and
suspension lines.
There are three basic types of Navy parachutes—
the Navy back (NB), the Navy chest (NC), and the
Navy ejection system (NES).
The NB and NC parachutes are used in aircraft that
do not have ejection seat systems. The NES is used in
ejection seat aircraft.
NES PARACHUTE
The NES parachute assembly (fig. 11-7) is used
only with ejection seat equipped aircraft. The assembly
is equipped with a 28-foot canopy. The canopy is
