Abstract: An undercarriage for an aircraft, an aircraft and an aircraft landing method are disclosed. The undercarriage includes: at least three bendable mechanical arms, wherein each mechanical arm includes a mount, a first link and a second link located in a same plane, the mount is connected with the aircraft, the mount is rotatable about an axis perpendicular to a bottom surface of the aircraft, the other end of the first link is pivotably connected with one end of the second link, and the other end of the second link is connected with a rotating wheel; a force feedback device configured to detect whether or not the mechanical arms receive forces, respectively; and drive mechanisms configured to respectively drive the mechanical arms to move such that in an outspreading process of the undercarriage, the drive mechanisms drive any one of the mechanism arms to be maintained in a current state when the force feedback device detects that the one of the mechanism arms receives a force.
