Cbu clarification

[Belisarius]

Am I correct?

Cbu 87 and 103 simply scatter a crapload of bomblets over target area, so wind not as much a factor

 

Cbu 97 and 105 are "sensor fused" and use parachutes and active sensor bomblets , wind more a factor and take longer to impact. Yes?

[Demongornot]

I can be wrong about it but.

 

Every bomb get influence on wing, the sensor fuzed get just more effect since it use parachute to slow down and stay longer in the air.

But CBU 87 still get influenced by the wing, the CBU 97 get more influence than the 87 cause of the parachute decent.

 

For both 103 and 105 its the same as 87 and 105 but with inertial navigation system that make them able to auto correct their course from wind effect.

The CBU 103 will probably be the bomb that get the less affected by the wind cause of corrected bomb and small (but not light) and fast bomblets.

The CBU 105 i think will get effect from the wind cause even if the main bomb get correction from the wind, the small sensor fuzed projectiles (the BLU-108) will still get deviation from wind.

 

I have not read it yet but i have found this :

The CBU-87 is cluster bomb which drops unguided nonsensored submuntions effective against infantry and light skinned vehicles. The CBU-87 becomes a CBU 103 when you put a WCMD kit onto the bomb.

 

The CBU-97 is a sensor fuzed cluster bomb which employs sensor fuzed bomblets which search for infrared targets effective against armored targets and vehicles. The CBU-97 becomes a CBU-105 when a WCMD kit is applied to it.

 

The WCMD attempts to guide the bomb using INS and GPS.

103 and 105s are wind corrected aren't they?

[nhowell01]

103 and 105s are wind corrected aren't they?

 

That's what gives them that designation in the first place. Without the WCMD( Wind Corrected Munition Dispenser) kit they are just CBU-87s or CBU-97s

[McBlemmen]

here's a great video that explains the 97s and 105s in extreme detail

Actually, the WCMD only uses INS.

[Sceptre]

How do you program the CBU burst height to be lower for a tighter spread? Do I just use the IFFCC?

You change it on the inventory page of the DSMS. Check out the video that was posted in this thread earlier. :o)

Actually every product spec page for the WCMD states differently.

[Eddie]

Actually every product spec page for the WCMD states differently.

 

No, they don't. WCMD as Howie quite correctly states is INS only.

 

WCMD-ER was an upgrade intended to add GPS assistance but it was cancelled.

[nhowell01]

No, they don't. WCMD as Howie quite correctly states is INS only.

 

WCMD-ER was an upgrade intended to add GPS assistance but it was cancelled.

 

In real life, does the the Aircraft not feed an update using its GPS sytem to the INS on the bomb regarding the targets location? I am not stating it is a GPS guided weapon.

[Eddie]

No. It provides positional data from the navigation system, aircraft navigation systems, the A-10C included, are not GPS they are INS assisted by GPS.

 

All positional data is INS based first and foremost, GPS is only there to eliminate any errors that would occur overtime due to gyroscopic drift etc. and the aircraft can operate entirely normally without GPS being available. JDAM is the same in that regard.
