Airbus Military/EADS A319 MPA

Initially you'd have to keep the plane level using the elevators. You could keep doing that indefinitely, but you don't want the extra drag. A fuel transfer balances the plane so you can fly level without deflecting the elevators.

How fast can that be done to accommodate the sudden C-of-G shift?

A Mk 46 torp weighs around 500 lbs, that's equivalent to around 74 US gallons. A 75 gpm pump is well within the realms of possibility on board an aircraft, tankers can transfer fuel at 1000 gpm or more, and that rate you could move a Mk 46s worth in 4.5 secs.

Progress: the fuselage is together, and I'm adding the radome under the nose. The plastic disk will be covered with Milliput, I'm using the disk as a guide for the final shape.

The radome is covered and ready, and I've drilled some holes for the sonobuoy launchers.

Wow...that looks awesome ! I've always loved the look of the 319, even more so in military guise !

A bit off there mate --
A US Gallon weighs 6.073 lbs which would make it 82.33 US Gallons
An Imperial Gallon weighs 7.29 lbs which would make it 68.59 Imp' Gallons

I like what you've done to the radome Harro, I've been thinking I need to do something like that to my Atlantic

Just one question:  Have you confirmed the sonobuoy launcher arrangement?  I ask since I suspect it is actually proposed to have twin rotary launchers somewhat similar to those for the P-8.  Although I have been unable to confirm this to be the case, the following picture from EADS seems to confirm this (the 2 yellow circles at the extreme end being the actual launchers):



It is also backed up by this image which although not showing any launch ports, certainly doesn't show a whole bank as you have done.



I hope you appreciate this is only raised to aid in your work.

But what's those four holes for just behind the wing root Greg ?

Not the sonobuoy launchers (based upon available public domain information).  As far as I can tell, they would be for the Decoy Dispenser - see below:

Interesting pictures Greg. Those show more info than I had.

I've been going mostly by this page. For the sonobuoys I used the ideas from this thread and took a guess that the 319 would use a mixed system with a couple of rotary launchers (3 or 4), plus some manual tubes.

Try downloading this:  http://www.c295.ca/wp-content/uploads/A319_MPA_pocket-guide.pdf?10615

It gives a bit more info.

As far as the sonobuoy launchers go, I think these days, it is preferred to go with the rotary launchers as it gives greater flexibility.

I don't think the manual tubes would give any advantage.  Realistically, the rotary magazines would be preloaded before the mission which would give you enough instant capacity (and effectively equal what the simple pre-loaded tubes would offer - after all it's not like all the tubes are fired in one salvo).

Well, I was thinking to have rotary launchers for the standard buoy types, and some manual tubes for launching the special items.

Thanks for the link, that'll be useful.

some manual tubes for launching the special items.

In that case, you could probably get by with some simple tubes (not pre-loaded kind) - here's what a P-3C has:




I think you could probably get by with 2 at most really.  IIRC the P-3C had more because it was a backup if the pre-loaded system totally failed (i.e. you would have guys 'shovelling' the sonobouys out the manual tubes).
