R-4360 Firing order
I read your post as to what would be the firing order of a P/W R-4360 and will post it for what it's worth today in the world of jets.
The order is read from left to right as for example A1-B5-C2-D6 and so on.
A B C D
1 5 2 6
3 7 4 1
5 2 6 3
7 4 1 5
2 6 3 7
4 1 5 2
6 3 7 4
Working with about 45 of these engines all our crews had to know the firing order to maintain and repair these "CORN COBS" as they were referred to.
The whys and wherefores are subtle and complex and it's too late in the morning for all of that___maybe later.
Hope that satisfies for now!
