CBU didn't burst/det. *trk file*

[razorseal]

Not sure what I did wrong. can someone please tell me what I did wrong, so I can fix it?

 

the CBU-97 didn't go off. There is a MRA setting I'm not too familiar with. Does it have something to do with that?

TL;DR:

The default F-15E burst height at 700 ft AGL is to low for DCS, so the canister/munitions hit the ground before the BLU-108 is able to trigger.

Adjusting the Fuse height to 1200 ft (IIRC DCS default for FC3) allowed the submitions to trigger and destroy the target vehicles.

Detail:

Spoiler

1. CBU-97 Burst Height @ 700 ft, dispensed BLU-108's hit one vehicle (none destroyed).

2. CBU-97 Burst Height @ 1200 ft, dispensed BLU-108's hit all seven vehicles (all destroyed).

Add Tacview BLU-108 pictures for CBU-97 700ft and 1200ft burst altitude settings.

I didn't see where I can adjust this. Is that the "1200" i see on the station on armt page on your screenshot? Do I just enter the numbers on ufc and hit the station osb?

 

Honestly when I fly thr f16 or a10, i never change any settings with thr cbu. So I'm not well versed in all its settings. Once I figure out how to change it to 1200, I'll try again.

 

What does the higher/lower burst alt do? Pro con to bursting at diff altitude? 

 

I believe there is also a rpm setting on other jets that allow them to be dispersed in a wider or tighter area.

Higher Burst Altitude = greater dispertion at the expense of greater wind drift.

In DCS with high  altitude drops, the main bomb casing picks up more speed and a higher burst altitude is required to allow the BLU-108 parachute to slow it's speed sufficiently for the rocket motor to fire at 100 ft.

IRL the fuse height is set on the ground and the PACS is set to match, AFAIK changing the burst height in flight is a DCS'ism.

AFAIK the F-15E's spin setting isn't "hooked up" yet.

Got it. Thanks!

 

How do you change the fuse height from the pacs? I'll see if I find a youtube vid on it but I didn't see it.

IIRC it's in the AG LOAD page.  Anything that would normally be set by ground crew should be up there, not PACS.

CBU-87 should be affected by SPIN setting, but AFAIK currently is not.  CBU-97 is not affected, since the body doesn't spin to disperse.

Here's a quick video demonstrating how to set the burst height afresh

Awesome thanks mate!
