Armament Interface Unit (AIU)

The Armament Interface Unit provides the functions to release, arm, control, operate, or jettison of various weapons carried by fixed- and rotary-winged aircraft.

It interfaces with the aircraft mission computer via the MIL-STD-1553B or RS-422 data bus. The interface also offers the MIL-STD-1760 compliance operation of non-1760 weapons. This enables the operation of new, sophisticated weapons as well as standard, common weapons through the same communication channel.

The AIU handles all the safety critical requirements of the armament. It can be adapted as a station interface unit or a wing interface unit dependent on aircraft configuration.

Features:

• Weapon operation
• Emergency jettison
• Modular configuration

Specifications:

Bomb release command	For single or multiple carriage
Arming	Nose or tail
Rocket fire command	Provision for quantity and interval selection
Gun / cannon operation	Gun fire command Preloading of number of rounds for each gun Burst-limit setting Automatic and manual recocking
Air-to-air missile operation	Missile launch command Control of power, cool, and uncage signals Head position and audio routing Provision for head slaving

Safety:

• No single failure can cause inadvertent firing, release, or jettison of weapon or stores
• Interface with both weight-on-wheels and wheels-up switches
• Weapon release or fire requires three independent actions
• Emergency jettison circuitry is independent of all other components and is implemented in hardware

Configuration:

• A single AIU interfaces with up to six weapon stations 
• Each wing interface unit interfaces with up to three weapon stations on a wing/stub wing 
• Each station interface unit interfaces with a single weapon station
