Most of the pictures I see of Mossie’s only seem to show 5 exhaust stacks on each side of the engine instead of the six I would have expected on a V12 !.
Did they route two exhaust stubs into one and if so for what reason, space or summat ? Did this happen with the early variants or was it only the later models with this type fitment.
Over to you.
Cheers

RE: Mossie exhaust’s
Hi Keith,
I can supply a few pictures & drwaings, but leave the interlectual part of how it all works to the professionals, like yourself.
So, lets see how good you all are, see if you can tell the different Merlins apart.

Nice one Neilly, do you think we should have a separate forum for engine lovers!

Thanks for the info and piccies guys, thats certainly clarified the exhaust query I had.
Thought it had to be summat simple !
I know the ‘ejector’ exhaust system used on some marks of ‘Spit’ increased the airspeed, but didn’t know about the same on the ‘Mossies’.
Once again
Cheers Guys

RE: Mossie exhaust’s
I would just add (just to confuse, a bit more), the shrouded exhaust is a totally different exhaust system, underneath. The exhausts were called saxophone exhaust, because that’s what they resembled. The reason this system was fitted was to give the Mosquito a higher top speed, because the way the exhuast gasses are funneled through created a ‘jet effect’ which in turn increaased the top speed by about 10-15 mph.
TTFN,
Neilly

RE: Mossie exhaust’s
The reason for pairing the last two sets of exhast stubs is quite simple – HEAT. If you look down on the Mosquito wing planform you can see that the radiator fairings come out a fair distance, so DH had to move the last stub forward. It wasn’t till the 2 stage Merlins were used that DH reverted back to 6 exhaust stubs. You can see from the side view of the nacelle how much longer the 2 stage nacelle is.
I hope the picture will explain a bit better than yours truely!
Cheers,
Neilly

RE: Mossie exhaust’s
it may well be because the first one is actually enclosed by the fairing that sits over the exhausts.
I dont know, it might be because one is routed into the other, havent actually gotten that close to find out exactly.
