With a total of 2 patents, his work focuses on enhancing the efficiency and safety of aircraft fuel systems.

Latest Patents

One of his latest patents is a "Device for regulating the pressure of an aircraft cryogenic fuel tank." This innovative pressure regulating device includes an on-board storage tank, a mixing chamber, first and second lines, a recirculation line, a pressure sensor, and a controller. The storage tank is designed to store and supply cryogenic fuel to a combustion chamber and features a booster pump. The first line supplies cryogenic fuel in a liquid state and includes a pressurizing pump and a first regulation valve. The second line supplies cryogenic fuel in a gaseous state and consists of a compressor and a first control valve. The recirculation line is equipped with a second regulation valve and a first heat exchanger. The pressure sensor detects the pressure inside the storage tank, while the controller manages the operation of the various components based on a setpoint pressure value.

Another significant patent is the "Circuit for supplying fuel to an aeronautical cryogenic turbomachine and associated method." This fuel supply circuit includes at least one cryogenic reservoir containing liquid fuel topped with a boil-off gas. It features a high-pressure liquid pump to supply the main propulsion device of the turbomachine with liquid fuel. Additionally, it includes an auxiliary turbomachine with an electric generator and a gas compressor to supply gaseous fuel. A buffer gas reservoir connects the gas compressor to the cryogenic reservoir, allowing for the reinjection of gas to maintain pressure above a predefined value.
