Abstract
A landing gear system may include: a casing coupled to a fuselage of an aircraft, such as an urban air mobility vehicle; a steering, one side of which is inserted into the casing and the other side of which is connected to a tire; a magnetorheological (MR) damper including a cylinder coupled to the casing and a piston coupled to the steering rod; a sensor unit configured to measure a condition of the urban air mobility vehicle; and a controller configured to control damping force of the MR damper based on measurement data of the sensor unit. The sensor unit may include a first sensor for measuring a stroke of the MR damper and a second sensor for measuring an acceleration of the casing.
Claims15
A landing gear system, comprising:
- a casing configured to couple to a fuselage of an aircraft;
- a steering rod comprising a first side inserted into the casing and a second side connected to a tire;
- a magnetorheological (MR) damper, in the casing, that comprises a cylinder coupled to the casing and a piston coupled to the steering rod;
- a sensor unit configured to acquire measurement data of a state of the aircraft;
- and
- a controller configured to control, based on the measurement data, a damping force of the MR damper;
- wherein the sensor unit comprises a first sensor for measuring a stroke of the MR damper and a second sensor for measuring an acceleration of the casing.
A landing gear system comprising:
- a casing configured to couple to a fuselage of an aircraft;
- a magnetorheological (MR) damper, in the casing, that comprises a cylinder coupled to the casing, a piston configured to absorb an impact of the aircraft and reciprocate linearly inside the cylinder, and an MR fluid configured to move between the cylinder and the piston;
- a sensor unit configured to check a relative motion condition of the cylinder and the piston;
- and
- a controller configured to control a magnitude of a current applied to the MR damper based on measurement data of the sensor unit.
