Ch 47 (rotary Wing Aircraft)

Picture of Ch 47 (rotary Wing Aircraft)

The AN/ALE-47 Airborne Countermeasures Dispenser System is used to protect military aircraft from incoming radar and infrared homing missiles. It works by dispensing flares or chaff. It is used on a variety of U.S. Air Force, Navy, and Army aircraft, as well as in other militaries.

The AN/ALE-47 countermeasure dispenser system was developed by Tracor, now part of BAE Systems,

The ALE-47 is integrated with the aircraft's radar warning receivers, missile warning receivers and other electronic warfare sensors. When the aircraft's sensors detect a threat, the countermeasure dispenser system automatically launches radiofrequency and infrared countermeasures at the optimum time to defeat incoming missiles. The ALE is compatible with a wide variety of countermeasures such as different types of flares and chaff. It is also designed to work with advanced future countermeasures.

The ALE-47 consists of a cockpit control unit, sequencer units, countermeasure dispensers and an optional programmer. The cockpit control unit provides an interface with the pilot. A programmer can be added to add extra features, such as advanced threat evaluation. It can also be used to fully integrate the system with an aircraft's glass cockpit eliminating the need for the cockpit control unit. The sequencer units control the dispensers, and are automatically capable of detecting misfires and correcting them. The sequencers are built into the dispenser units on the rotary-wing version. Each dispenser can hold five different types of countermeasures for a total of 30. The whole system can accommodate up to 32 dispensers on fixed-wing aircraft and 16 on rotary-wing aircraft.
