Patent number: 10597135Abstract: In order to simplify the connection of a door to the outer envelope of an aircraft cell, it is provided to dispose the door into a portion of the outer envelope having tilted sides, as is the case at the nose cones and the tail cones of conventional airplanes, and in various portions of blended wing body airplanes and flying wings. Thus, the door can be configured to displace, in rectilinear translation, from one of its extreme opening and closing positions to the other, without requiring that the door protrudes outside of the outer envelope in the closing position.Type: GrantFiled: December 20, 2016Date of Patent: March 24, 2020Assignee: AIRBUS OPERATIONS SASInventors: Olivier Cazals, Jaime Genty De La Sagne

Publication number: 20170167437Abstract: A jet engine comprises at least three zones including an air intake zone and an exhaust zone. The axis of the air intake zone is not coincident with the axis of the exhaust zone of the engine, the engine as a result, having at least two intersecting axes and being referred to as a multiaxial engine. Therefore, the jet engine has at least two zones with different longitudinal axis orientations: by choosing an axial orientation of the zones of the engine that are more sensitive to a detachment or breakage of elements of the gas generator, it is possible to also choose a direction of the possible paths of these detached elements, to avoid them striking the opposite engine.Type: ApplicationFiled: December 14, 2016Publication date: June 15, 2017Inventors: Olivier Cazals, Julien GUILLEMAUT

Patent number: 8876044Abstract: An aircraft having an elongated fuselage and a lifting surface fastened to the fuselage. The aircraft has a device for controlling the torque around the yaw axis GZ of the aircraft in which aerodynamic forms that have devices to generate aerodynamic drag are fastened to each end of the lifting surface at non-zero distances from each side of a vertical plane of symmetry XZ of the aircraft. The drag-generating devices are commanded to produce a different aerodynamic drag at each of the two ends to generate a yaw torque on the aircraft. The aerodynamic forms, for example, have winglets improving the aerodynamics of the lifting surface, and are provided with aerodynamic drag generators.Type: GrantFiled: July 30, 2010Date of Patent: November 4, 2014Assignee: Airbus Operations S.A.S.Inventors: Olivier Cazals, Thierry Druot

Patent number: 8820676Abstract: Swiveling engines attached to the fuselage by struts, for example to the rear part of the fuselage are used to control the pitch and yaw movements of an aircraft. The swivel axes of the engines are oriented to form a V so that swiveling one engine creates a variation of the vertical and lateral components of the engine thrust. Controlled swiveling of the two swiveling engines makes it possible to generate a component of the resultant thrust in a vertical plane that can be controlled in direction and intensity to generate pitch and yaw torques. The swiveling engines also include pods provided with jet deflection flaps for the engine considered, and the struts are profiled and provided with a trailing edge control surface using ruddervator architecture.Type: GrantFiled: March 30, 2009Date of Patent: September 2, 2014Assignee: Airbus Operations SASInventors: Olivier Cazals, Thierry Druot
