Latest Patents
Hagihara's latest patents include an EHA system for lifting and lowering landing gear. This system features a hydraulic circuit equipped with a hydraulic actuator designed to lift or lower the leg of an aircraft. It incorporates at least one electric hydraulic pump, a hydraulic path, a pressure sensor, a temperature sensor, and a control unit. The control unit is responsible for outputting a control signal to operate the electric hydraulic pump during the lifting or lowering process. Additionally, the hydraulic circuit includes a pressure-increasing element, allowing for effective health monitoring of the electric hydraulic pump based on various operational parameters.
Another significant patent is the landing gear lifting/lowering EHA system. This system consists of a hydraulic actuator, electrically operated hydraulic pumps, a hydraulic path, and a pressure sensor. The controller in this system outputs a control signal to the hydraulic pump, ensuring that if the hydraulic pressure exceeds a set limit for a specified duration, the pump will stop and only resume operation once the pressure drops to a safe level.
