초록

A control and method is provided that continuously adjusts fuel sensitive schedules in the ECU for changes in the heating value of the fuel being combusted by the engine. The control and method includes calculating, as the engine is running, an expected fuel flow for a baseline fuel type and an actual fuel flow. A ratio of these two fuel flows is determined and applied to the heating value of a baseline fuel type that is preprogrammed into the ECU. This results in a scale factor that is then applied to fuel sensitive schedules in the ECU.

청구항

[ What is claimed is:] [1.]1. A method for adjusting schedules in an electronic control unit for a gas turbine engine for variation in fuel type comprising the steps of:calculating an expected fuel flow for a baseline fuel type as said engine is running;calculating an actual fuel flow;taking a ratio of said expected fuel flow to said actual fuel flow;determining a fuel schedule scale factor by applying said ratio to the heating value of said baseline fuel type; andapplying said scale factor to said schedules.
