Afraid sm969 has gone to usa guys....

[Anacinc]

Really?.... Not again! We lost a fair amount of special aircraft to the US already, and I would like to see a stunning flightline again like they had during the 90's!

Pitty RR changed the firing order on the big Griffon, makes it sound more like a radial instead of the more common pure of its older brother the Merlin with the Allisons, and the big DB-603's, most 12 cylinder engines don't sound like the Griffon.

[Anacinc]

Why should it be a pitty? Lot of the WW2 era planes from the allied forces used the Merin engine and speaking in terms of war it didn't matter what an engine sounded like but these days I would love to hear a Griffon engined fighter among all those Merlin or even Packard Merlin engined planes. Keep in mind that the Merlin, DB's, Allison, Jumo, Klimov all had different firing orders. Probably the Griffon had a pretty radical change in firing order which gives it's distinctive sound ;)

[planedrawer]

Your right. I've seen a schematic on a website(think it's Aero Engine History) of all the V-12 firing orders, including the E-type jag engine, which is identicle to the DB600's! I was surprised to see that they were all different, even though all but the Griffon sound alike. When you look @ the Griffons firing order it is the most different. I think it was an attempt by RR to stop the big crank breaking between the strain of the prop & supercharger.

[Anacinc]

Not really sure how this radical firing orde came about. Your right about the site where the info concerning firing orders is available, that;s where I got the info as well. Never could have guessed that they had a different approach for each V12 engine but ok... always awesome to hear them!

I want to find out how to do it, but I don't know how.
