  • Publication number: 20260084662
    Abstract: A motorized landing gear including: a motor housing that encloses a motor; a gearbox; a controller; and a power source powering the motor and the controller. The gearbox attaches to an axle having two ends, with a first end of the axle connecting to a first landing gear leg and a second end of the axle connecting to a second landing gear leg. The motor connects to said gearbox and the controller instructs the motor to rotate. The rotation of the motor transfers power to the gearbox, which rotates the axle. The rotation of the axle in a first direction simultaneously telescopes the landing gear first leg and the landing gear second leg; and the rotation of the axle in a second direction simultaneously retracts the landing gear first leg and the landing gear second leg.
