Gas turbine engine fuel control system

摘要

A fuel control system having a combustive energy value evaluator determining a combustive energy value of the fuel, and a controller calculating a desired flow rate based at least on the combustive energy value and controlling a fuel metering device such that the fuel flow rate corresponds to the desired fuel flow rate.

主权项

1. A system for monitoring a flow of a liquid fuel mixture of different types of fuel in a gas turbine engine, the system comprising:
a sensor sensing a proportion of each of the different types of fuel in the liquid fuel mixture; a unit determining a combustive energy value of the liquid fuel mixture in the engine from the proportions; a controller determining at least one equivalent characteristic of a reference fuel corresponding to the combustive energy value of the liquid fuel mixture; and a display unit displaying the at least one equivalent characteristic.
