Merlin 66 sfc curve

[Trilisser]

Anyone out there with a specific fuel consumption curve for Merlin 66? Preferably one giving data for +18 boost/300 rpm and +7 boost/2650 rpm.

I don't have the ops manual specific to the M66, and I don't have a curve I can find, however it is likely to be similar to the M63, M63a, M64, M72, M73 chart below. The M66 maintenance manual specifies a max fuel flow demand of 154 gallon/hr (fuel pump delivery).

Although not answering your question, this might help.

Please be aware that the last column is pints per horsepower hour. And the British may have been using an Imperial pint to go with the Imperial gallon?

All power levels in the chart would be rich mixture.

Thanks! This is very helpful!

Not quite: that cruising setting of 2650 rpm/+7 boost is a lean mixture rating.
