MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202617085652 A) filed by Safran Helicopter Engines on July 13, 2026, for Method For Controlling The Fuel Flow Rate Of A Helicopter Turbine Engine.
Inventors include Flechoux, Bastien; Marty, Frederic, Georges, Roger; Marin, Jean-Philippe, Jacques; and Derbez, Denis, Guillaume.
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: The present invention relates to a computer-implemented method for controlling the flow rate of fuel injected into a combustion chamber (42) of a turbine engine (4) of a helicopter (1) by means of a fuel metering device (50), the method comprising the following steps: - calculating a fuel flow rate setpoint in accordance with a desired speed of the turbine engine (4); - calculating a virtual fuel flow rate corresponding to an increase or decrease in the temperature in the combustion chamber according to a thermal model (M, M') of the turbine engine comprising an intrinsic thermal model of the turbine engine influencing the temperature in the combustion chamber; - correcting the fuel flow rate setpoint of the virtual fuel flow rate; - controlling the fuel metering device so that it injects an amount of fuel that complies with the corrected fuel flow rate setpoint (C2) into the combustion chamber.
