reverser for engine 1 (left). T/R 2 is the thrust reverser for
engine 2 (right).
Each T/R has a left and right half. Each half has a translating
sleeve which moves aft for reverse thrust. The sleeves work at
the same time, but are independent from each other. Three
hydraulic actuators move each sleeve. Rotary flex shafts make
sure that the hydraulic actuators extend and retract at the same
rate.
T/R Control System
The T/R control system lets you deploy the T/R when the
airplane is less than 10 feet (3 meters) from the ground. You
give a deploy signal to the control system when you raise a
reverse thrust lever.
You supply a stow signal when you return the reverse thrust
lever to the stow position.
The T/R control valve module controls hydraulic power to the
hydraulic actuators. The reverse thrust lever operates the
switches necessary to send a deploy or stow signal to the T/ R
control valve module.
The sync locks prevent the operation of the hydraulic actuators
when there is no deploy signal.
The primary purpose of the engine accessory unit (EAU) is to
control the T/R stow operation. The EAU supplies front panel
built-in-test equipment (BITE) to help you do troubleshooting of
the control system. The EAU uses two T/R proximity sensors for
each translating sleeve for control. The EAU also interfaces with
the T/R indicating system to control the REVERSER light.
T/R Indicating System
The T/R indicating system supplies these indications in the
flight compartment:
* REV message on common display system (CDS)
* REVERSER light on the P5 aft overhead panel
* Linear variable differential transformer (LVDT) data on the
control display unit (CDU).

The common display system (CDS) shows the REV message.
This message refers to the positions of a T/R’s translating
sleeves. Each T/R has LVDTs which supply translating sleeve
position data to the electronic engine control (EEC).
When on, the REVERSER light shows that there is a failure in
one of these areas:
* T/R control system
* Mechanical failure which prevents the control system from
correct operation.
The REVERSER light comes on for 10 seconds during a T/R
stow operation. The light will stay on if the T/R does not stow in
10 seconds. The EAU controls this light.

Purpose
The thrust reverser (T/R) system controls the direction of
engine fan air exhaust for forward and reverse thrust.
Reverse thrust helps decrease the speed of the airplane after
landing or during a rejected take off (RTO).

General
The T/R is a translating sleeve and cascade design. Each T/R
has a left and right fan duct half with a translating outer wall
(sleeve). The two sleeves on each T/R work at the same time.
However, the sleeves are independent of each other.
Each T/R half has these components:
