Q

ASE components

A
  • Missile Warning Set (MWS), AN/AAR-47A(V)2 or AN/AAR-47 B(V)2
  • Electronic Support Measures (ESM), AN/ALQ-210
  • Infrared Countermeasures Set (IRCM), AN/ALQ-144C(V)5
  • Countermeasures Dispensing System (CMDS), AN/ALE-47(V)
2
Q

IOSC

A

Integrated Optical Sensor Converter. The B(V)2
additional capability to detect noise patterns in the UV clutter (tonal noise), enhanced probability of
timely missile detection (Pd), but it comes with a small increase in false alarm rate (FAR).

3
Q

AAR-47 MWS

A

Passively detect attacking IR missiles and battlefield lasers (range finder, target designator, and beam rider missiles)

360 degree coverage for the aircraft with coverage divided into four 90-degree zones
centered at 45, 135, 225, and 315 degree relative headings

Missile Warning Aperture
HARLID
Phododiode Laser Warning Aperture
Dynamic Blanking Adjunct Detector

4
Q

Missile Warning Aperture

A

Wide FOV detectors that sense UV radiation from rocket motor plume/other man made sources

Evaluates photon count streams for temporal patterns

5
Q

Laser Warning

A

500-1600 nm region

HARLID - AOA info
Photodiode - Quadrant only, but can detect weak laser signals

Asterisk*

6
Q

HFI

A

Hostile Fire Indication

Quadrant indication

Small arms/unguided munition

7
Q

SSDP

A

Stores and self defense program

Contained in the SSDC

8
Q

CP

A

Countermeasures Signal Processor

9
Q

Blanking

A

To prevent false laser threat warnings from reflected laser energy. Default for laser blanking is OFF, it must be enabled on the MTS main menu to function

UV blanking function shutters the IOSC to
protect it from damage by high levels of UV energy.

10
Q

System Operation

A

Under normal operating conditions, the SSDP processor in the MC maintains
1553 communication with the MWS. In this state, all threats detected by the MWS are passed to the SSDP, and
are displayed in the ASE display, and also on the horizontal situation indicator (HSI) on the flight display (FD).

11
Q

ALQ-210

A

replicates every HTW emitter report to the weapons 1553B bus

“RWR” (radar warning receiver)

12
Q

ALQ-144

A

upper/lower - The transmitter
generates infrared light, modulates it, and then passes it through the covert window in the form of invisible
IR energy to disrupt the thermal imaging of missile threats, provides omni-directional support

Jam Select 1-9

13
Q

ALQ-144 System Turning On

A

60 second warm up

Lower transmitter disabled via WOW switch

14
Q

IRCM alerts

A

The four monitored functions are high frequency and low frequency modulator speeds, source emission, and high temperature.

If an IRCM failure alert
is observed, the system should be powered down immediately by turning the ON/OFF switch on the OCU to OFF. After the 60 second cool down period is completed the power distribution circuits shut down. The IRCM jammer
system is turned off and the UPPER/LOWER IRCM INOP
alerts are removed.

16
Q

CMDS Sequencer

A
  • Generates and routes firing power to specific payload locations in the dispenser assembly
  • Conducts BIT
  • Determines magazine identification (16 unique loadouts)
  • Monitors inventory
17
Q

Polling

A

polling every 5 minutes, verifying squib continuity

18
Q

Bypass

A

Dispense one of each with Bypass mode

Jettison available (SEL)

19
Q

Magazine Assembly

A

30 1.42 inch cartridges

Breechplate has MAG ID and routes firing signal

20
Q

MAG ID

A

ABCD; 1234

MDF relies on correct setting to determine which of the 16 configurations is present.

21
Q

DISPENSE SWITCH

A
  • Selected Manual Program (1 – 6) in MAN mode.
  • Manual Program 5 in SEMI mode if there is no DISPENSE READY indication.
  • Manual Program 5 in AUTO mode.
  • Dispense in SEMI mode if DISPENSE READY is illuminated.
  • Bypass program in BYPASS mode.
22
Q

Squib power removed when

A
Safe
Dispenser safety pin
WOW
CB's pulled
ISD OFF

expendables cannot be dispensed by any means

Squib power still on with “CMDS OFF”
