Chaff and Flares

[Deadman]

Here is a list of chaff and flare dispensers use in aircraft that may be of some help

[VMFA117_Poko]

Eclair (Alkan LL5062) flare dispensers beneath the rear fuselage (in line with the wing trailing edge, each with 16 parachute-retarded flares)

In Y2K AdA retained the old countermeasures system with the Serval/Sabre/Spirale units. MATRA Spirale comprises chaff dispensers (112 bundles in each) at the rear of the Karman fairings; twin Alkan LL5062 as Kusch said.

Mirage 2000 Spirale pdf

 

About Alkan systems little more info can be found here:

http://www.alkan.fr/22chafa.htm

Second position in decoys despenser subpage shows system (-5165-) dedicated for FAA Hercules also. Design to house one magazine C730 for 6 cartridges diam 55 mm. IR or EM. (shown on next subpage - magazines). Forgive me lack of good quality photos.

 

C-130J Countermeasures:

 

The ATK AN/AAR-47 missile warning system uses electro-optic sensors to detect missile exhaust and advanced signal processing algorithms and spectral selection to analyse and prioritise threats. Sensors are mounted near the nose just below the second cockpit window and in the tail cone.

 

The BAE Systems AN/ALR-56M radar warning receiver is a superheterodyne receiver operating in the 2GHz to 20GHz bands. A low-band antenna and four high-band quadrant antennae are installed near the nose section below the second window of the cockpit and in the tail cone.

 

The BAE Systems Integrated Defense Solutions (formerly Tracor) AN/ALE-47 countermeasures system is capable of dispensing chaff and infrared flares in addition to the POET and GEN-X active expendable decoys.

 

The Lockheed Martin AN/ALQ-157 infrared countermeasures system generates a varying frequency-agile infrared jamming signal. The infrared transmitter is surface mounted at the aft end of the main undercarriage bay fairing.

 

The USAF has selected the Northrop Grumman Large Aircraft Infrared Countermeasures (LAIRCM) system to equip its C-130 aircraft. LAIRCM is based on the AN/AAQ-24(V) NEMESIS.

Huh ? Are you sure ? Eclair (Alkan LL5062) is the large IR dispenser that can be mounted under the plane (rear fuselage) in the parachute compartment. I think that what you are talking about is the Spirale Cartridge Dispenser Modules (CDM)

Are you sure too ? Spirale is a 112 chaffs + 16 flares decoying system that uses 2 chaff dispensers (ICD) at wing root and two flare cartridges dispensers (CDM) under the fuselage near the ICD :)

Eclair is another system that provides a massive (at least for our french standard) IR protection (almost 4 times Spirale one) :)

 

I think you should have a look at those links, the small pictures are really worth it :) :

And a little picture to illustrate everything :)

HubMan, You're right - 112 chaffs + 16 flares. Check link to pdf in the beginning of my previous post.

Hi Poko24 :)

 

Thanks for the link :) using the small schema at the top of the page would have avoided me the dirty edition of the beautifull picture from airliners.net :D

 

Cheers :)

Many thanks Hub.

Thanks Poko and HubMan, excelent sources.

S-3B uses two AN/ALE-39 Blocks, one on each side.

 

...two AN/ALE-39 chaff-flare dispensers, one on each side of the rear lower fuselage, with a load of 30 cartridges each.

 

One "Block" holds 30 cartridges:

It seems that the E-2C has no countermeasure dispeners.

[thereminqblank]

This page says that the AH-64A has M130 chaff dispensers 'on either side of the rear tailboom'. I take this to mean there are two dispensers. Each dispenser holds 30 chaffs, giving a total of 60. Interestingly, this website says that they generally don't carry flares as they hit the tail rotor and set vegetation on fire.

CH-47D

 

This July 2002 article

http://www.nationaldefensemagazine.org/issues/2002/Jul/Upgraded_Chinook.htm

 

explains the upgrade of US Chinooks from the CH-47D to CH-47F. It says that the upgrade makes provision for a second M130 dispenser. Therefore, I assume that the CH-47D had one dispenser, holding 30 chaff/flares.

[Groove]

AH-1W: 2xAN/ALE-39 = 120 Chaffs/Flares

[Groove]

Lates Ch-47 pictures indicates that they hold 4xM-130 Chaff/Flare Dispensers. Two on each side below the tail rotor. Although it seems they use this configuration in areas where MANPADs are suspected.

Eep, seems that the Taiwanese Chinooks (pics from 2007) have 8 dispensers:

Thanks for the update thereminqblank, i talked about the one used in the Afghanistand and Iraq.

 

CH-47 seems to be using 2 x AN/ALE-39. One on each side as seen in the picture here:

Fair enough. I just saw the other pics and thought I'd mention it seems the Chinook can carry 8.

 

That's the CH-53 you've linked to, not the CH-47

Is it approved info?

Incomprehensible fact. IMHO, one of main threats for helicopters is IR manpads.

[Groove]

Not 100% because its not verified by a official source. But all the webpages on the internet dont say anything about countermeasures on this plane. Some even say : countermeasures - no flare / haff dispensers.

 

Here is a walkaround:

I thought it was just in peacetime/training missions where they didn't carry flares for fear of brushfires. I'm sure they'll carry them if they're going to war somewhere with a high threat of IR-missiles. They're certainly able to carry flares.

 

Also some other nations using Apaches have added new countermeassures on the wing tips. Don't know the details of those though.

Is it mistake?

Each AN/ALE-39 contain 30 charges. No?
