Patent number: 11975822Abstract: A method of determining a service interval for an actuator of a landing gear assembly is suitable for used with a landing gear assembly in which the actuator positions the landing gear assembly between a stowed position and a deployed position. The method includes the steps of determining an actuator travel value for a time interval and increasing a total actuator accumulated travel value by the actuator travel value for the time interval. The method further includes the step of comparing the total actuator accumulated travel value to a predetermined value.Type: GrantFiled: November 9, 2020Date of Patent: May 7, 2024Assignees: Safran Landing Systems, Safran Landing Systems Canada Inc.Inventors: Andrew Michael Ellis, Graeme Peter Arthur Klim, Aakash Gohil, Pierrick Géraud Alexandre Lemonnier, Leszek Marian Dacko

Publication number: 20240102513Abstract: A pin for a pinned joint includes a hollow body with a first and second end caps coupled to first and second ends, respectively. The body and the end caps at least partially define a cavity within the body, wherein at least one aperture extends through the hollow body. A main piston is slidably disposed within the cavity and divides the cavity into a first chamber proximate to the first end and a second chamber proximate to the second end and fluidly isolated from an environment around the body. A lubricant is disposed within the first chamber. The main piston moves toward the first end of the body when a pressure in the second chamber is greater than a pressure of the environment. Movement of the main piston toward the first end of the body discharges lubricant through the at least one aperture.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Applicants: SAFRAN LANDING SYSTEMS, SAFRAN LANDING SYSTEMS CANADA INC.Inventors: Andrew Michael ELLIS, Aakash GOHIL, Graeme Peter Arthur KLIM

Patent number: 11761851Abstract: A drive system includes a motor having a rotatable output shaft that is operably coupled to a lead screw by a transmission that converts rotary output of the motor into linear translation of the lead screw. The drive system further includes a position sensor configured to sense a position of the lead screw. A method for determining a backlash of the drive system includes the steps of sensing an initial position and driving the lead screw in a first direction to a calculated second position by controlling the motor to rotate the output shaft an amount that corresponds to a distance between the initial position and the calculated second position. The method further includes the steps of sensing an actual second position of the lead screw; and determining a backlash value according to a difference between the calculated second position and the actual second position.Type: GrantFiled: May 31, 2022Date of Patent: September 19, 2023Assignees: Safran Landing Systems Canada Inc., SAFRAN LANDING SYSTEMSInventors: Aakash Gohil, Andrew Michael Ellis, Graeme Peter Arthur Klim, Dorian Tercier

Patent number: 11447157Abstract: A passive lateral stability system maintains the position of a vehicle relative to a guideway. The system includes first and second guide assemblies that urge the vehicle away from first and second electrically conductive guide walls, respectively. The first guide assembly includes a wheel configured to reciprocate toward and away from the first guide wall. A biasing element bias biases the wheel toward the first guide wall. The system further includes a magnetic element associated with the wheel, wherein movement of the magnetic element relative to the first guide wall produces a magnetic force that biases the wheel away from the first guide wall. A second guide assembly is mounted to the vehicle and urges the vehicle away from the second guide wall.Type: GrantFiled: May 6, 2020Date of Patent: September 20, 2022Assignees: SAFRAN LANDING SYSTEMS, SAFRAN LANDING SYSTEMS CANADA INC.Inventors: Graeme Peter Arthur Klim, Justin Guang Yuang Cheng, Andrew Michael Ellis
