Distributed landing gear system architecture for electromechanical actuation

A landing gear system, comprising:

• a nose gear door motor;
• a nose gear motor drive unit in operable communication with the nose gear door motor;
• a nose gear retraction-extension motor in operable communication with the nose gear motor drive unit;
• an alternating current direct current converter electrically coupled to the nose gear motor drive unit;
• a controller in operable communication with the nose gear motor drive unit;
• and
• a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:
• receiving, by the controller, a pilot command;
• determining, by the controller, a nose landing gear power sequence for providing power to the nose gear door motor and the nose gear retraction-extension motor in response to receiving the pilot command;
• and
• outputting, by the controller, a first command to the nose gear motor drive unit, wherein the nose gear motor drive unit is configured to power either the nose gear door motor or the nose gear retraction-extension motor based on the first command from the controller.

A system for controlling landing gear subsystems, comprising:

• a controller;
• a first motor drive unit in operable communication with the controller;
• a first electric motor in operable communication with the first motor drive unit;
• a second electric motor in operable communication with the first motor drive unit;
• a second motor drive unit in operable communication with the controller;
• a third electric motor in operable communication with the second motor drive unit;
• a fourth electric motor in operable communication with the second motor drive unit;
• and
• an alternating current direct current converter electrically coupled to the first motor drive unit and the second motor drive unit.
