CBU-97/105 Submunitions dispense incorrectly

SpecterDC13 · February 2

What is happening in DCS vs what should happen:

When the TMD separates two of the three pieces stick together and follow the submunition dispenser down. What should happen is the TMD should blow away and the force from the wind should cause it to go aft of the submunition dispenser. This does not affect anything from what I can tell inside DCS, it is more of a visual inaccuracy right now.

The submunitions are then dispersed individually rather than together (FWD section followed by AFT section) on the CBU-105. This is done correctly on the CBU-97 but not correctly for the CBU-105. The way they disperse the submunitions should not change. It should still go all FWD, then all AFT. They should not dispense individually.

In DCS if you use a HOF of 1500 two or more submunitions collide with the ground. If you use a HOF setting of 1200 (standard) you will lose up to 5 with the CBU-105 and up to 11 with the CBU-97. From what I can tell this is happening due to a long chute deployment interval time once the submunitions are released from the bays. What should happen with a HOF of 1200 or 1500, is all the submunitions in the FWD bay get released and they should almost instantly start deploying their chutes one after another, then all the AFT bay submunitions should do the same. There should not be any that collide with the ground.
Judging by the pattern of how the submunitions disperse under certain wind conditions makes me believe that you guys are modelling the CBU-105B/B which has the P3I munition in it. Even if the CBU-105/B, which uses the Baseline munition, was being modelled it should not have submunitions crash into the ground with a HOF setting of 1200. With a setting of 1200 (which is standard) the dispensers will still open at a predetermined altitude AGL. Depending on which one you are modelling will depend which altitude is correct.

Right now, the only way to avoid losing any submunitions to ground collision is to set a HOF of 1800 or more.

Here is a video to show a CBU-97 in action. Timestamp 4:33.

In the video you can see how the TDM separates and then the FWD submunitions disperse, followed by chute deployment almost instantly (and the video is in slow motion.) In DCS it takes a while for the submunitions to deploy the chutes.

Attached are tracks with various drops with 1500, 1200, and 900 HOF used. They are all short and can be watched and slowed down to view the submunitions going into the ground. Along with some pictures.

And also, for the CBU-97, visually it has a WCMD tail package when it shouldn't for obvious reasons. Should be all green not silver. That is the biggest way to tell the difference between a WCMD and non-WCMD CBUs. Which you can also see in the video as well.

Another thing I noticed, when dropping a single CBU another dispenser appears for some reason at some point. You can watch the track here to see it.f16c_cbu105_1200_test3_double.trk

The only thing that separates the 105 from the 97 is the WCMD tail kit. Everything else is exactly the same as the 97.
