Patent number: 10298097Abstract: An electromechanical machine includes at least one coil made from a material that becomes electrically superconducting when its temperature is below a critical temperature. A functional part is contained in an internal volume of a thermally insulating and fluid-tight enclosure of the machine. A wall of the insulating enclosure is traversed in a fluid-tight fashion by at least one shaft for transmitting mechanical power between the functional part located in the internal volume of the insulating enclosure and a space outside the insulating enclosure. The functional part can be used as a heat sink, pre-cooled to maintain the temperature conditions for maintaining superconductivity inside the insulating enclosure.Type: GrantFiled: December 18, 2013Date of Patent: May 21, 2019Assignee: AIRBUSInventors: Hichem Smaoui, Charles Nespoulous, Bruno Rechain, Emmanuel Joubert

Patent number: 10138899Abstract: An electric propulsion assembly for an aircraft includes a nacelle having a nacelle cowl which defines an inner space for arranging an electric propulsion unit, which includes a blower, of the aircraft. An electric motor assembly is placed in the inner space and connected to the propulsion unit to supply power to the propulsion unit. An airflow generated by the blower flows in a space between the motor assembly and the nacelle cowl defining a duct to supply thrust to the aircraft. A power electronics system has at least one heat exchanger to transfer thermal energy from the system to a work fluid to cool the system. The heat exchanger is placed to project at least partially into the duct, so that the work fluid consists of the air flow generated by the blower.Type: GrantFiled: June 13, 2014Date of Patent: November 27, 2018Assignee: AIRBUS SASInventors: Emmanuel Joubert, Hichem Smaoui, Charles Nespoulous, Bruno Rechain

Patent number: 9932129Abstract: A device for moving aircraft along the ground includes at least one runway and at least one aircraft. The aircraft is secured to a tractor element having a magnetic mass formed mainly of type II superconductor material and the runway includes stator coils arranged in the runway with at least one line of coils parallel to an axis of the runway. A command/control system supplies power to the stator coils to generate a magnetic field that levitates the tractor element, magnetized beforehand into a phase II superconducting state, above the runway.Type: GrantFiled: June 11, 2014Date of Patent: April 3, 2018Assignee: AIRBUS SASInventors: Emmanuel Joubert, Charles Nespoulous, Bruno Rechain, Hichem Smaoui

Patent number: 9677466Abstract: A method of managing a power demand to assure the operation of a pilotless aircraft. The aircraft includes an internal combustion engine supplying a maximum principal power which can vary. The management method is particularly suitable for a rotary wing pilotless aircraft. It guarantees the storage of an amount of electrical energy at least equal to a recovery energy of the aircraft in the event of failure of the internal combustion engine. This recovery energy enables the control of autorotation and landing of the aircraft.Type: GrantFiled: December 11, 2015Date of Patent: June 13, 2017Assignee: AIRBUS GROUP SASInventors: Hichem Smaoui, Bruno Rechain, Fabien Retho

Patent number: 9643713Abstract: A method of manufacturing a stiffened panel having a skin and at least one substantially elongate stiffener having a longitudinal groove forming a cavity. At least one storage device for storing and releasing electrical energy. The longitudinal groove is filled with at least one storage device for storing and releasing electrical energy. The storage device is covered with a skin which forms the cavity together with the longitudinal groove of the stiffener. A stiffened ring can be derived from the method.Type: GrantFiled: September 9, 2013Date of Patent: May 9, 2017Assignee: AIRBUS GROUP SASInventors: Michel Bermudez, Didier Mesnage, Hichem Smaoui, Benoit Fleury
