Publication number: 20210009254Abstract: A landing control method for an aircraft includes detecting whether a landing indication signal is received, controlling the aircraft to automatically land in a pre-set landing mode in response to the landing indication signal being received, detecting whether a landing control signal sent by a user is received, and, in response to the landing control signal sent by the user being received, modifying the pre-set landing mode according to the landing control signal to determine a modified landing mode. The landing control signal includes a first control signal for changing a pre-set attitude in the pre-set landing mode or a second control signal for changing a pre-set speed in the pre-set landing mode. The method further includes resuming the pre-set landing mode in response to the landing control signal being discontinued.Type: ApplicationFiled: September 29, 2020Publication date: January 14, 2021Inventor: Canlong LIN

Publication number: 20210009255Abstract: Disclosed herein is a system for actuating a flap coupled to a wing of an aircraft in a streamwise direction. The system comprises a geared rotary actuator comprising a drive gear that is rotatable about a first rotational axis. The system also comprises a crank shaft comprising a driven gear in gear meshing engagement with the drive gear of the geared rotary actuator to rotate the crank shaft about a second rotational axis. The second rotational axis is angled relative to the first rotational axis. The system further comprises a crank arm co-rotatably coupled to the crank shaft and configured to be coupled to the flap. Rotation of the crank shaft about the second rotational axis rotates the crank arm in a direction perpendicular to the second rotational axis.Type: ApplicationFiled: July 9, 2019Publication date: January 14, 2021Inventors: Bryan J. Gruner, Kevin Tsai

Publication number: 20210009257Abstract: High-lift systems and related methods are described. An example apparatus includes a fixed wing and a Krueger flap movably coupled to the fixed wing between a stowed position and a deployed position. The Krueger flap includes a first flap portion movably coupled to the fixed wing and a second flap portion movable coupled to the first flap portion. The first flap portion moves relative to the second flap portion between a retracted position and an extended position. The first flap is to move to the retracted position in response to the Krueger flap moving to the stowed position. The first flap is to move to the extended position to define an aerodynamic surface in response to the Krueger flap moving to the deployed position.Type: ApplicationFiled: July 10, 2019Publication date: January 14, 2021Inventors: Arvin Shmilovich, Eric David Dickey
