signals for the programmed payload ejection
sequences. It also generates control signals for single
ejection of payloads initiated manually. Manual
(single) dispensing is performed during a programmed
dispensing sequence without disrupting the program.
AN/ALE-37A COUNTERMEASURES CHAFF
The AN/ALE-37A countermeasure chaff dis-
pensing set (fig. 10-23) is externally mounted on
aircraft IMER/ITER ejector racks that have 14-inch
suspensions. When mounted on the aircraft, the
AN/ALE-37A has various patterns of chaff, decoy
dependent upon control settings and aircraft speed.
Several dispensing pods may be employed on a single
The dispensing set is of modular construction,
making maintenance easier and reducing turnaround
time. Each dispensing pod contains two lightweight
payload modules. Each payload module has a capacity
of 120 rounds, providing a total capacity of 240 rounds.
When empty, the pod weighs 180 pounds. When fully
loaded, the pod weighs approximately 277 pounds.
The functional theory and a physical description of
individual dispensing set components are discussed in
the following paragraphs. As you read about the
components, look at figure 10-24. It shows their
location and identifies them by item number.
