Corrected fuel flow is the fuel flow that is required by an engine if the freestream total head conditions are equivalent to ambient conditions at Sea Level on a Standard Day (i.e. 14.696 lb/in², 288.15K ).
Corrected Fuel Flow can be calculated as follows, assuming Imperial units:
So-called Non-Dimensional Fuel Flow
Corrected Fuel Flow (or Non-Dimensional Fuel Flow) is one of several non-dimensional groups associated with gas turbine performance calculations.
The equivalent equations for Preferred SI Units are:
