BRU-33 release logic: 2 bombs dropping from same wing


Recommended Posts

Posted

Normally when I carry two BRU-33s or four BRU-33s and drop bombs in pairs, they will drop one bomb from each wing, but today I had something funky happen and two bombs dropped from the same wing.

 

My payload was 1x centerline fuel tank, 6x Mk82s, 2x AIM-9Ms in a configuration commonly used by Hornets in Desert Storm. The inboard pylons had one BRU-33 with two bombs each, and the outboard pylons had one bomb each:

As you can see I'm dropping ripple pairs with 75' spacing between each bomb, which typically releases one bomb from each side to keep things symmetrical.

 

However, with this payload of 6 bombs, one bomb was released from the outboard pylon and one bomb was released from the inboard BRU-33 from the same wing, making my aircraft imbalanced. Here's my STORES page after the first release:

Should I be using the STEP key to select a certain store to get them to release from both wings, or is something buggy with this particular payload combination?

Change your MULT value to 2. If I remember how it works, QTY is the total number of bombs that will be release, MULT controls how many stations will release bombs.

 

e.g. QTY 2, MULT 1 should drop 2 bombs total from 1 station.

QTY 2, MULT 2 should drop 2 bombs total between 2 stations.

e.g. QTY 2, MULT 1 should drop 2 bombs total from 1 station.

QTY 2, MULT 2 should drop 2 bombs total between 2 stations.

 

 

 

So would another way to think of it is QTY = number of commanded consecutive releases, MULT = how many in each commanded release? Or do I have it backwards?

This is not true. The only thing setting MULT to 2 would do is cause them both to drop at the exact same time with no interval between them.

 

I can't think of a reason that both would drop from the same wing.

QTY x MULT = total number dropped. Therefore QTY 2 MULT 2 would drop four bombs. QTY 2 MULT 1 drops two bombs, and is proven to do so with other payload combinations (i.e. 8x bombs on 4 BRU-33s, 4x bombs on 2 BRU-33s, 4x bombs direct on pylons).

 

 

I went back and looked at my video, I had the outboard single bomb selected. I will try today with the BRU-33 racks selected on my first pass instead and see what happens.

Nope, QTY = Total number dropped. MULT = how many drop per interval.

Ah! That sounds correct.

 

So setting QTY 2 MULT 2 it will drop a pair then drop another pair for a total of 4.

 

QTY 3 MULT 2 drops three, then three, total six

 

QTY 2 MULT 3 drops 2, drops 2, drops 2, total six

No you misinterpreted Rennes, QTY is the TOTAL.

I see. The MULT function is rather confusing due to its nomenclature. I wish they had named it something else.

 

Anyway, I ran three tests with the 6xM82 load with 500ft intervals so that the release logic could be easily seen:

 

Here's the original issue with the single outboard bomb selected first.

Here I tried selecting the inboard BRU33 and the release logic worked the first time, but the system automatically selected the single outboard bomb afterwards, causing a return to the original issue.

And here I had to manually select the BRU33 stations for both drops to maintain a symmetrical release pattern.

Okay. Wow. I was way off understanding this. Thanks!

"Unable to step through all GBUs loaded, Incorrect release sequence are fixed."

 

Fixed in the next update.

Okay, the release sequence is fixed for this particular config, but the bug still remains in another common Desert Storm config:

 

2x wing tanks, 2xBRU33s with 2 bombs each, 1 bomb centerline (total 5 bombs). Bombs will step from left BRU33, right BRU33, then centerline. Shouldn't it prioritize BRU33s first, then select centerline last?

The way to look at it is

 

"Release QTY bombs in multiples of MULT, with INT feet between multiples"

 

So QTY 4 MULT 2 INT 300= "Release 4 bombs in multiples of 2 with 300 feet between" = 2 pairs dropped 300ft between pairs

 

This is why if you select QTY4 MULT4, you don't get INT because the entire quantity getting released at once.

Yes, we've established what QTY and MULT are, but that is not the issue here. The issue is the system stepping through bombs in such an order as to cause imbalance.

The graphic is ambiguous for mixed carriage. The explicit answer is in the NTIP manual, which is not available publically.

 

Reading between the lines, stores carried on BRU-32 parent racks would follow the same initial pattern as the BRU-33 sequence, starting with the centerline.
