Latest Patents

Among his latest patents are a pump actuating device and an associated pumping system, as well as a method for fuel supply in aircraft. The actuating device for a fuel pump in an aircraft engine features a motor, a generator, and an electrical connection member. The motor is designed as an asynchronous machine with Dahlander coupling, which includes a first rotor coupled to the pump for actuation. The first stator comprises at least one input phase, with each input phase containing two windings. The generator includes a second rotor mechanically linked to the engine's shaft and a second stator with at least one output phase. The electrical connection member is configured to connect each output phase to an input phase, allowing the windings of each input phase to be connected in series or parallel based on the engine's speed.

Another significant patent is the actuation system for an aircraft engine lubrication pump. This system includes a generating rotating electrical machine with a first stator that has at least one output stator winding. It also features a driving rotating electrical machine with a second rotor intended to actuate a lubrication pump, along with a second stator that includes at least one input stator winding. An array of switches is electrically connected to both stator windings, enabling them to be connected or disconnected based on the state of the switches. A control device manages the array of switches according to a control signal, determining whether to connect the output and input stator windings.
