Method of providing an accurate volume-mass law for fuel consumption

摘要

The invention is related to a method of providing an accurate volume-mass law for determination of a fuel flow rate of an engine, particularly providing a fuel flow rate to a helicopter turbine, comprising the steps of: Determining a sample type of fuel and a start density Á o of said sample type of fuel in said fuel tank using an equation Á 0 =aT+b 0 , with a and b 0 being known for said sample type of fuel and calculating real time offset parameters b n from an algorithm to determine real time densities p of the fuel.
