Okay, now lets try the pictures!
In terms of the gunfire system the basic principle is to have a large box under A & B, Q and X & Y turrets. Each box contains a smoke generator so three in all.
There will be two valves at the top which connect a 6mm pipe to one gun in A turret and one gun in B turret. There is a separate 1" square valve behind which rests a computer fan motor.
The other guns in A and B will contain a very high intensity LED to give the flash, with the whole lot connected to a sound module for the "bang".
Sequence of operation is as follows:
1) Smoke generator on for 3 seconds to fill the box - all valves shut
2) Open valves for 1.5 Seconds and shut offf the smoke generator, initiate the fan for the same time and initiate the LED flash for half second and the sound module
3) Switch off fan and close the vlaves simutaneously
4) Repeat as required
On a practical basis all turrets will operate at the same time so I get a salvo of 5 shots. The smoke generators typically draw 3 amps at 12 volts so 9 amps in all but lets call it 10 amps for 3 seconds for each salvo of 5 shots.
Lets start with a 10amp hour 12 volt battery which is nominaly 10 amps for one hour or one amp for 10 hours. I know this doesn't work in practice and is an over simplification but let's continue.
There are 60 seconds in a minutes and 60 minutes in an hour so 60 x 60 = 3,600 seconds all in divided by 3 seconds = 1,200 theoretical shots. If we use a factor of 50% we get 600 salvos minimum which x 5 (1 for each turret) = 3,000 shots over all. Now this all seems to be far too high so even if we multiply this by 50% again we get 300 salvos and 1,500 shots. You get the picture. Even if the current consumption is 6 amps this would halve everything again (may need to make the smoke generators work faster) we still get 150 salvos and 750 shots!
I'm fairly sure there is a flaw in my maths but believe the concept to be sound and I can always add another battery, or two, given eht size of Iron Duke to make up for any shortfall.
As always the devil is in the detail, how to construct and operate the valves and sequencing but I believe the theory to be sound.
Do please let me have any thoughts please
